Drinking Water Grade O-ring Materials

Seals in drinking water systems are continuously exposed to moisture, chlorine, ozone, biofilms, and temperature cycling, all of which can compromise elastomer integrity over time. Common issues include hardening, swelling, bacterial buildup, and loss of elasticity, which may lead to leaks or contamination. Canyon Components’ sealing materials are formulated to resist hydrolysis, oxidative degradation, and microbial growth. Compounds such as EPDM provide excellent resistance to hot water, steam, and chloramine disinfectants, while FKM and FFKM compounds handle higher temperatures and aggressive cleaning cycles in industrial water systems. Our materials are engineered to retain their compression properties and sealing force even after years of service, ensuring consistent performance and safety. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Material selection depends on temperature, pressure, and chemical conditions in the system, along with the individual requirements of the system that the seals will be going into. EPDM is the most common choice due to its superior resistance to water, steam, and common sanitizing agents. It offers excellent flexibility and is approved under both NSF 61 and WRAS standards. Silicone is preferred for low-temperature flexibility and applications requiring transparency or high elasticity. FKM and FFKM are ideal for systems that require resistance to aggressive chemicals, cleaning agents, or elevated temperatures, such as high-purity or industrial water systems. Canyon Components works with customers to match each application with the correct compound, ensuring a balance of compliance, performance, and longevity. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Every water-safe material supplied by Canyon Components undergoes independent testing and third-party certification to confirm compliance with NSF, WRAS, and related international standards. These tests assess both chemical leachability and mechanical durability, ensuring that seals do not introduce metals, plasticizers, or volatile compounds into the water supply. Our EPDM and FKM compounds are tested for tensile strength, elongation, hardness, and compression set retention after prolonged water immersion. Canyon Components also maintains detailed material traceability and provides documentation packages with Certificates of Conformance, compliance statements, and batch records. This ensures that each O-ring or gasket meets exact specifications and can be traced back through production and testing. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. Chlorine and chloramine are commonly used in water disinfection, but they can rapidly degrade standard elastomers. Canyon Components offers chloramine-resistant EPDM and FKM formulations that maintain integrity in both treated and recirculated water systems. Certain EPDM compounds are specifically engineered to resist oxidative damage and maintain elasticity after extended exposure to chlorinated water. These materials are ideal for use in filtration units, valve housings, and distribution components that experience continuous flow or stagnation under chlorinated conditions. For applications involving mixed oxidants or high-temperature sanitization, our FFKM and high-fluorine FKM materials provide superior chemical resistance and extended service life. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Certified seals are essential in virtually every component that handles potable water, including pumps, filters, valves, flow meters, storage tanks, and distribution fittings. They are also used in hot water systems, beverage dispensing units, and water purification assemblies where hygiene and compliance are critical. Canyon Components supplies both standard AS568 O-rings and custom-molded parts for these applications. We can manufacture large-diameter seals for flanged pipe joints or micro-sized O-rings for small valve assemblies. All parts are produced to tight tolerances and cleanroom packaged to prevent contamination during installation or storage. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. Our NSF 61 and WRAS certified compounds are rated for continuous operation in both hot and cold water service. EPDM materials provide reliable sealing from -71°F to 302°F (with some blends capable of 554°F steam exposure), making them suitable for both chilled and heated systems. FKM materials extend that temperature range up to 437°F, allowing use in hot water and steam systems without loss of elasticity. Silicone compounds perform exceptionally well in low-temperature applications, maintaining flexibility where other elastomers become brittle. Canyon Components ensures that every material retains its compression properties across the entire operating range, preventing leaks during temperature cycling and long-term service. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. In addition to NSF 61 and WRAS, our sealing materials can also meet KTW, ACS, and W270 standards depending on regional requirements. These certifications cover European and international potable water applications, verifying that seals are safe and durable across various water chemistries. Canyon Components regularly supports customers in obtaining multi-regional compliance for global projects, ensuring seamless approval for use in municipal, industrial, or residential systems. Our materials are tested for microbial resistance and non-toxicity to maintain universal safety in drinking water applications. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Absolutely. Many drinking water systems require unique seal geometries or dimensions for proprietary valves, manifolds, or housing designs. Canyon Components offers custom-molded, die-cut, and extruded seals made from NSF and WRAS certified materials. Our engineers can design seals optimized for groove compression, flow direction, and installation force. We also provide bonded metal-to-rubber assemblies and multi-material components that combine structural support with compliant sealing materials. Whether you need large-diameter gaskets for tank flanges or miniature seals for inline regulators, we deliver precision-molded parts with full compliance certification and traceable documentation. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!
