Industry Overview

The flexible metal hose industry is highly fragmented and diverse, with more than eight companies producing flexible metal hose in the U.S., and at least that many in Europe and Asia. Because of its simple and ubiquitous nature, flexible metal hose has been applied to a number of different applications across a broad range of industries.

The major market categories for flexible metal hose include (1) automotive, (2) aerospace, (3) residential, commercial, and institutional construction, and (4) general industrial. Omega Flex participates in the latter two markets for flexible metal hose. The residential and commercial construction market utilizes corrugated stainless steel tubing (CSST) primarily for flexible gas piping and double containment piping for conveying diesel fuel and gasoline from a storage tank to a dispenser or back-up generator. The Company produces corrugated copper tubing for medical gases in medical care facilities, including hospitals, clinics, dental and veterinary offices, and long-term care facilities. The general industrial market includes all the processing industries, the most important of which include primary steel, petrochemical, pharmaceutical, and specialty applications for the transfer of fluids at both extremely low and high temperatures, (such as the conveying of cryogenic liquids) and a highly fragmented OEM market, as well as the maintenance and repair market.

None of our competitors appears to be dominant in more than one market. We believe that we are a leading supplier of flexible metal hose in each of the U.S. markets in which we participate. Our assessment of our overall competitive position is based on several factors. The flexible gas piping market in the U.S. is currently concentrated in the residential housing market. Based on the reports issued by the national trade groups on housing construction, the level of acceptance of flexible gas piping in the construction market, and the average usage of flexible gas piping in a residential building, we believe that we can estimate with a reasonable level of accuracy the size of the total gas piping market. Based on our sales, the Company believes it can estimate its position within that market. For other applications, industry trade groups collect, and report data related to these markets, and we can then compare and estimate our status within that group as a whole. In addition, the customer base for the products that we sell, and the identity of the manufacturers aligned with those customers is fairly well known, which again allows the Company to extract information and estimate its market position. Lastly, the term “leading” implies a host of factors other than sales volume and market share position. It includes the range and capability of the product line, history of product development and new product launches, all of which information is in the public domain. Based on all this information, the Company is reasonably confident that it is indeed a leader in the major U.S. market segments in which it participates.

Development of Business

Incorporated as a Pennsylvania corporation in 1975 under the name of Tofle America, Inc., the Company was originally established as the subsidiary of a Japanese manufacturer of flexible metal hose. For a number of years, the Company was a manufacturer of flexible metal hose that was sold primarily to customers using the hose for incorporation into finished assemblies for industrial applications. The Company later changed its name to Omega Flex, Inc., and in 1996, the Company was acquired by Mestek, Inc. (Mestek).

In 2005, Mestek distributed its equity ownership in our common stock to Mestek shareholders and the shares of our common stock started trading on The NASDAQ Stock Market LLC under the stock symbol “OFLX.”

Over the years, most of the Company’s business has been concentrated in North America, but the Company also has foreign subsidiaries located in the U.K. and France, which are largely focused on European and other international markets. The Company also has a U.S. subsidiary which owns the Company’s Exton, Pennsylvania real estate and, in October 2024, formed a new U.S. subsidiary, Flex-Trac, Inc., for its MediTrac®corrugated medical gas tubing products.

Overview of Current Business

Strategy

The Company’s strategy has been, and continues to be, focused on its core strengths in the development, manufacture, and sale of flexible metal hose for use in a variety of applications. We believe the Company is uniquely situated to exploit its capabilities in this area due to its long experience in engineering and bringing new products to market, and its proprietary rotary process, which permits the Company to manufacture flexible metal hose with superior quality and efficiency as compared to its competitors. The Company’s strategy is to develop flexible metal products in new and developing markets that would recognize and compensate for the value-added propositions that each product brings to that industry. Typically, this would involve a new flexible metal hose that replaces traditional rigid products, and thereby improves the quality of the installed product, increases installation efficiency, and provides an overall cost and time savings. Examples of such products are our flexible gas piping sold under the TracPipe®CounterStrike®trademarks, our MediTrac®corrugated medical gas tubing, our DoubleTrac®double-containment piping, and DEF-Trac®flexible piping. In each instance, we believe that the products we bring to market offer customers superior quality, expanded applications due to the products’ flexibility, and reduced total costs. The Company seeks to protect its investments in product development by obtaining patent protection for new and unique features of its products.

Sales, Products and Customers

We sell our products to customers scattered across a wide and diverse set of industries ranging from construction to pharmaceutical. These sales channels include sales through independent sales representatives, distributors, OEM, and direct sales. We utilize various distribution companies in the sale of our TracPipe® and Counterstrike®CSST, and these distribution customers in the aggregate represent a significant portion of our business. In particular, the Company has one significant distribution customer, whose various branches had sales in the range of 13% to 15% of total sales during the years of 2025 to 2024 and were 22% and 23% of the Company’s accounts receivable balance as of December 31, 2025 and 2024, respectively. All of this business is done on a purchase order basis for immediate resale commitments or stocking, and there are no long-term purchase commitments. In the event we were to lose an account, we would not expect any long-term reduction in our sales due to the broad end-user acceptance of our products. We would anticipate that in the event of a loss of any one or more distributors, that after an initial transition period, the sales of our products would resume at or near their historical levels. Furthermore, in the case of certain national distribution chains, which is the case regarding the Company’s largest customer noted above, and other distributors, it is possible that there would continue to be purchasing activity from one or more regional or branch distribution customers. We sell our products within North America, primarily in the U.S. and Canada, and we also sell our products internationally, primarily in Europe through our manufacturing facility located in Banbury, U.K. Our sales outside of North America were about 3% of our total sales during the last two years, with most of the sales occurring in the U.K. and elsewhere in Europe.

TracPipe®CSST

The Company has had the most success within the residential construction industry with its flexible gas piping products, TracPipe®CSST, which was introduced in 1997, and its more robust counterpart TracPipe®CounterStrike® CSST, which came to market in 2004. Partnered with the development of our AutoFlare® and AutoSnap®fittings and accessories, both have enjoyed wide acceptance due to their reliability and durability. In late 2023, we discontinued the AutoSnap® fitting, due to overwhelming market acceptance of the AutoFlare® fitting. Within the residential construction industry, the flexible gas piping products that we offer, and similar products offered by our competitors have sought to overcome the use of black iron pipe that has traditionally been used by the construction industry in the U.S. and Canada for the piping of fuel gases within a building. Prior to the introduction of the first CSST system in 1989, nearly all construction in the U.S. and Canada used traditional black iron pipe for gas piping. However, the advantages of CSST in areas subject to high incidence and likelihood of seismic events had been first demonstrated in Japan. In seismic testing, the CSST was shown to withstand the stresses on a piping system created by the shifting and movement of an earthquake better than rigid pipe. The advantages of CSST over the traditional black iron pipe also include lower overall installation costs because it can be installed in long uninterrupted lines within the building.

The flexibility of the tube allows it to be bent by hand without any tools when a change in direction in the line is required. In contrast, black iron pipe requires that each bend in the pipe have a separate fitting attached. This requires the installer to thread the ends of the black iron pipe, apply an adhesive to the threads, and then screw on the fitting, all of which is labor intensive and costly, including testing and rework if the work is not done properly. As a result of these advantages, the Company estimates that CSST now commands over one-half of the market for fuel gas piping in new and remodeled residential construction in the U.S., and the use of rigid iron pipe, and to a lesser degree copper tubing, accounts for the remainder of the market. The Company plans to continue its growth trend by demonstrating its advantages against other technologies, in both the residential and commercial markets, in both the U.S. and overseas in geographic areas that have access to natural gas distribution systems.

CounterStrike® CSST

As previously mentioned, in 2004, the Company introduced a new brand of flexible gas piping sold under the registered trademark “CounterStrike®”. CounterStrike® CSST is designed to be more resistant to damage from transient electrical arcing. In a lightning strike, the electrical energy of the lightning can energize all metal systems and components in a building. This electrical energy, in attempting to reach ground, may arc between metal systems that have different electrical resistance, and arcing can cause damage to the metal systems. In standard CSST systems, an electrical bond between the CSST and the building’s grounding electrode would address this issue, but lightning is an extremely powerful and unpredictable force. CounterStrike®CSST is designed to be electrically conductive and therefore disperse the energy of any electrical charge over the entire surface of the CounterStrike®line. In 2007, the Company introduced a new version of CounterStrike®CSST that was tested to be even more resistant to damage from electrical arcing than the original version, and substantially more effective than standard CSST products. As a result of its robust performance, the new version of CounterStrike® CSST has been widely accepted in the market, and thus during 2011, the Company made the decision to sell exclusively CounterStrike® CSST within the U.S. This move demonstrated the Company’s commitment to innovation and safety and further enhanced its leadership in the marketplace.

DoubleTrac® Piping

In 2008, the Company introduced its first double containment piping product – DoubleTrac®. DoubleTrac® double containment piping has earned stringent industry certifications for its ability to safely contain and convey liquid fuels. DoubleTrac®piping received certification from Underwriters Laboratory, the testing and approval agency, that our product is fully compliant with UL 971A, which is the product standard in the U.S. for metallic underground fuel piping, ULc S679 which is the product standard in Canada for metallic underground fuel piping, as well as approvals from other relevant state agencies that have more stringent testing procedures for the product. Additionally, DoubleTrac® is fully compliant with UL 1369, which is the bi-national U.S. and Canada standard for aboveground piping for flammable and combustible liquids. DoubleTrac® piping is one of a select few piping systems having listings and approvals for both belowground and aboveground piping systems. Similar to our flexible gas piping, DoubleTrac® piping provides advantages over older rigid pipe technologies. DoubleTrac® piping is made and can be installed in long continuous runs, eliminating the need for manually assembling rigid pipe junctions at the end of a pipe or at a turn in direction. In addition, DoubleTrac® piping has superior performance in terms of its ability to safely convey fuel from the storage tank to the dispenser, primarily because DoubleTrac® piping is essentially a zero permeation piping system, far exceeding the most stringent government regulations. Originally designed for applications involving automotive fueling stations running from the storage tank to the fuel dispenser, the ability of DoubleTrac® piping to handle a variety of installation challenges has broadened its applications to include refueling at marinas, fuel lines for back-up generators, and corrosive liquids at waste treatment plants. In short, in applications where double containment piping is required to handle potentially contaminating fluids or corrosive fluids, DoubleTrac® piping is engineered to handle those demanding applications.

DEF-Trac® Piping

DEF-Trac® piping, a complementary product which is very similar to DoubleTrac® piping, was brought to the marketplace in 2011. DEF-Trac®piping is specifically engineered to handle the demanding requirements for diesel emissions fluid (DEF). Federal regulations require all diesel engines to use DEF to reduce the particulate contaminants from the diesel combustion process. However, DEF is highly corrosive and cannot be pre-mixed with diesel fuel. This requires that new diesel trucks and automobiles must have separate tanks built into the vehicle so that the diesel emissions fluid can be injected into the catalytic converter after the point of combustion. Similarly, a large portion of fueling stations carrying diesel fuel are now also selling DEF through a separate dispenser. In addition to being highly corrosive, DEF also has a high freezing temperature, requiring a heat trace in the piping in applications in northern areas of the U.S. DEF-Trac®flexible piping is uniquely suited to handle all of these challenges, as the stainless steel inner core is corrosion resistant, and DEF-Trac®piping also comes with options for heat trace that is extruded directly into the wall of the product. In summary, DEF-Trac®piping provides a complete solution to the demanding requirements of this unique application, as such, DEF-Trac® piping has been met with wide acceptance from the industry that was searching for a solution to the new environmental requirement. The advantageous market position of DEF-Trac®has leveraged the penetration of DoubleTrac® piping into the broader market for automotive fueling applications.

MediTrac® Corrugated Medical Tubing

In 2019, the Company commercialized MediTrac® corrugated medical tubing (“CMT”), following its 2018 launch with several beta sites. Developed for the healthcare industry, the product can be used in hospitals, ambulatory care centers, dental, physician and veterinary clinics, laboratories, and any facility that uses medical gases (oxygen, nitrogen, carbon dioxide, etc.). Made from a copper alloy with an exterior fire-retardant jacket, MediTrac® is made and sold in long continuous-length rolls. MediTrac®CMT’s flexible nature and storage in rolls allows it to be transported to and installed in health care facilities much more easily and quickly than traditional medical grade rigid copper pipe, which generally comes in 20 foot long sections. MediTrac® CMT is unrolled from a spool and installed in a medical facility in one long continuous length and is bent by hand when a change in direction is needed. The long lengths and ability to change direction with ease eliminates labor that would otherwise be needed to braze connections to straight sections of copper pipe or elbows or tees for changes in direction, while increasing installation efficiency and operational safety and minimizing downtime for healthcare facilities. Easy to assemble axial swaged brass fittings connect with all K, L and DWV medical tubing that is sized from ½” to 2” in diameter and provides a leak-tight seal using ordinary hand tools. The patented fitting also prevents tampering or disassembly using a tamper-proof sleeve that is required by the Health Care Facilities Code (NFPA 99 – 2018 edition). Rated at 185 psig, MediTrac® CMT can deliver the necessary volume of gas wherever it is needed across a facility. A recent case study comparing the installation of rigid copper pipe and MediTrac® CMT showed that MediTrac® CMT increases installation efficiency by a factor of five (i.e., a 500% increase in efficiency). By reducing the number of joints and brazed connections, MediTrac® CMT also reduces possible contamination into the medical gas system along with the fire risk associated with brazing. MediTrac® CMT is currently listed at UL 1365 and has an ASTM E84 rating of 25/50 and meets all 2018 requirements of the Health Care Facilities Code (NFPA 99 – 2018). MediTrac® CMT also meets Canadian standard Z7396.1, Medical Gas Pipeline Systems.

In 2020, the MediTrac® product line experienced increased sales in use and acceptance in the marketplace resulting from its ability to be quickly and safely installed to meet the unprecedented crisis caused by the COVID-19 pandemic. Numerous medical institutions and emergency medical centers used MediTrac® CMT to quickly install medical gas lines in tent hospitals or in converted facilities to handle the surging demand. For example, MediTrac® medical gas piping was installed in a City of New York temporary hospital located in Central Park and in the Cleveland Clinic for patients with COVID-19 infections and in need of supplemental oxygen treatments. On September 25, 2020, the Centers for Medicare & Medicaid Services (CMS) issued a waiver allowing the use of CMT in new and existing healthcare facilities based on the provisions in NFPA 99 – 2018, allowing MediTrac® CMT to be installed in all facilities in the U.S.

In 2024, the Company formed a new U.S. subsidiary, Flex-Trac, Inc., for the MediTrac®CMT product line.

Additional Market Applications

In addition to the flexible gas piping and other previously described markets, our flexible metal hose is used in a wide variety of other applications. Our involvement in these markets is important because just as the flexible gas piping applications have sprung from our expertise in manufacturing metal hose, other applications may also evolve from our participation in the industry. Flexible metal hose is used in a wide variety of industrial and processing applications where the characteristics of the flexible hose in terms of its flexibility, and its ability to absorb vibration and thermal expansion and contraction, have substantial benefits over rigid piping. For example, in certain pharmaceutical processing applications, the process of developing the specific pharmaceutical may require rapid freezing of various compounds through the use of liquefied gases, such as liquefied nitrogen, helium or hydrofluorocarbons. The use of flexible metal tubing is particularly appropriate in these types of applications. Flexible metal hose can accommodate the thermal expansion caused by the liquefied gases carried through the hose, and the total length of the hose will not significantly vary. In contrast, fixed or rigid metal pipe would expand and contract along its length as the liquid gases passed through it, causing stress on the pipe junctions that would over time cause fatigue and failure. Alternatively, within certain industrial or commercial applications using steam, either as a heat source or in the industrial process itself, the pumps used to transfer the liquid or steam within the system are subject to varying degrees of vibration. Additionally, flexible metal hoses can also be used as connections between the pump and the intake of the fluids being transferred to eliminate the vibration effects of the pumps on the piping transfer system. All of these areas provide opportunities for the flexible metal hose arena, and thus the Company continues to participate in these markets, as it seeks new innovative solutions which will generate additional revenue streams for the future.

In each instance, whether the application is for CSST for fuel gases, flexible metal hose for handling specialty chemicals or gases, flexible double containment piping, unique industrial applications requiring the ability to withstand wide variations in temperature and vibration, or copper alloyed CMT for medical facilities, all of our success rests on our metal hose. Most of our flexible metal hoses range in diameter from 1/4” to 2” while certain applications require diameters of up to 16”. All of our smaller diameter pipe (2” inner diameter and smaller) are made by a proprietary process that is known as the rotary process. The proprietary process that we use to manufacture our annular hose is the result of a long-term development effort begun in 1995. Through continuous improvement over the years, we have developed and fine-tuned the process so that we can manufacture annular flexible metal hose on a high speed, continuous process. We believe that our own rotary process for manufacturing annular corrugated metal hose is the most cost efficient method in the industry, and that our rotary process provides us with a significant advantage in many of the industries in which we participate. As a result, we can generally provide our product on a demand basis. Over the years, the Company has had great success in achieving on-time delivery performance to the scheduled ship date. The quick inventory turnover reduces our costs for in-process inventory and further contributes to our gross profit levels.

Markets and Competition

There are approximately eight manufacturers or importers of flexible metal hose in the U.S., and at least that many in Europe and Asia. The U.S. manufacturers and importers include Titeflex Corporation, ASC Engineered Solutions, Pro-Flex, Microflex Inc., Hose Master, Pennflex, and several smaller privately held companies. No one manufacturer or importer, as a general rule, participates in more than two of the major market categories, automotive, aerospace, residential and commercial construction, and general industrial, with most concentrating on just one. We estimate that we are at or near the top position of the two major categories in which we participate regarding U.S. market share. In the flexible gas piping market, the U.S. market is currently concentrated in the residential housing market. Based on the reports issued by the national trade groups on housing construction, the level of acceptance of flexible gas piping in the construction market, and the average usage of flexible gas piping in a residential building, as well as through our sales position within that market, we can estimate with a high level of accuracy the size of the total gas piping market. For other applications, industry trade groups collect and report on the size of the relevant market, and we can estimate our percentage of the relevant market based on our sales as compared to the market as a whole. The larger of our two markets, the construction industry, has seen a modest decrease in the number of residential housing starts in 2025, as compared to the previous year. As discussed elsewhere, black iron pipe or copper tubing was historically used by all builders of commercial and residential buildings until the advent of flexible gas piping and changes in the relevant building codes. Since that time, flexible gas piping has taken an increasing share of the total amount of fuel gas piping used in construction.

Due to the number of applications in which flexible metal hose may be used, and the number of companies engaged in the manufacture, import and sale of flexible metal hose, the general industrial market is very fragmented, and we estimate that no one company has a predominant market share of the business over other competitors. In the market for double containment piping, we compete primarily against rigid pipe systems that are more costly to install than DoubleTrac® double containment piping. For medical tubing applications, the main competitor is medical grade (Type K or Type L) rigid copper pipe. MediTrac® CMT is the only corrugated medical tubing in the U.S. that is approved to the stringent requirements of UL 1365. The general industrial markets within Europe are very mature and tend to offer opportunities that are interesting to us in niche markets or during periods in which a weak dollar increases the demand for our products on a competitive basis. Currently, we are not heavily engaged in the manufacture of flexible metal hose for the aerospace or automotive markets, but we continue to review opportunities in all markets for our products to determine appropriate applications that will provide growth potential and high margins. In some cases, where the product offering is considered a commodity, price is the overriding competing factor. In other cases, a proprietary product offering, or superior performance will be the major factors with pricing being secondary, and in some cases, an even lesser factor. Most of our sales are to distributors and wholesalers, and our relationships with these customers are on an arms-length basis in that neither we nor the customers are so dependent on the other to yield any significant business advantage. See Note 2, Significant Accounting Policies — Significant Concentrations, to the Consolidated Financial Statements included in this report for additional details. From our perspective, we can maintain a steady demand for our products due to broad acceptance of our products by end users, regardless of which distributor or wholesaler sells the product.

Resources and Raw Materials

We use various materials in the manufacture of our products, primarily stainless steel for our flexible metal hose and plastics for our jacketing material on TracPipe® CounterStrike®CSST and DoubleTrac® double containment piping, as well as a copper alloy for our MediTrac®CMT. We also purchase all of our proprietary fittings for use with the TracPipe® and CounterStrike®CSST, DoubleTrac® double containment piping, and MediTrac®CMT. We have multiple sources qualified for all of our major raw materials and components. Nickel is a prime material in stainless steel which the Company utilizes to manufacture CSST, and copper is a key component of the Company’s brass fittings and our MediTrac® CMT. Fortunately, the Company was able to maintain reasonably stable margins during 2025 even though the cost of copper, along with the impact of tariffs upon stainless steel, increased towards the end of the year. We believe that with our purchase commitments for stainless steel, polyethylene and for our proprietary fittings, we have adequate sources of supply for these raw materials and components. Like most other manufacturers, we had sporadic supply chain issues in 2025, but we believe our multiple suppliers have sufficient raw materials and capacity minimizing any potential disruption. We believe that the supply sufficiency of stainless steel will continue until there is a reduction in global capacity, such as mine closures, which would then cause constriction. Volatility in the commodities marketplace, tariffs, and competitive conditions in the sale of our products could potentially restrict us from passing along raw materials or component part price increases to our customers.

Government Regulations, Including Environmental Regulations

The Company believes that its businesses and operations, including its manufacturing plants and equipment, are in substantial compliance with all applicable government laws and regulations, including those related to environmental, consumer protection, international trade, labor and employment, human rights, tax, anti-bribery, and competition matters. Any additional measures to maintain compliance are not expected to materially affect the Company’s capital expenditures (including expenditures for environmental control facilities), competitive position, financial position, or results of operations.

Various legislative and administrative regulations applicable to the Company in the matters noted above have become effective or are under consideration in many parts of the world. To date, such developments have not had a substantial adverse impact on the Company. However, if new or amended laws or regulations impose significant operational restrictions and compliance requirements upon the Company or its products, the Company’s business, capital expenditures, results of operations, financial condition and competitive position could be negatively impacted. Refer to Item 1A. Risk Factors for further information.

Human Capital

As of December 31, 2025, the Company and its subsidiaries had approximately 172 full-time employees and no part-time employees.
