Chemical Processing O-ring Materials

Most failures in chemical processing seals occur due to chemical incompatibility, thermal degradation, compression set, and extrusion damage. Incompatible materials can absorb chemicals, swell, or lose their mechanical properties, while thermal cycling leads to hardening or cracking. Improper gland design or excessive pressure can cause extrusion, tearing, or permanent deformation. Canyon Components prevents these issues by providing materials that meet specific chemical and thermal compatibility standards. We also assist customers with seal groove design optimization, ensuring uniform compression and avoiding overloading or under-filling of glands. Every seal is engineered to handle both static and dynamic stresses in high-pressure and high-temperature chemical systems. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Our most chemically resistant materials include FFKM compounds such as Canrez®, Kalrez®, and Chemraz®, which perform reliably in contact with virtually all process media including concentrated acids, caustics, hydrocarbons, and halogenated solvents. These materials are ideal for critical systems such as pumps, mechanical seals, and high-purity reactors. FKM (fluorocarbon) compounds are suitable for less extreme environments that involve hydrocarbons, oils, or mild acids, offering an economical balance between resistance and flexibility. EPDM provides excellent resistance to steam, hot water, and polar chemicals, while silicone performs well under extreme temperature variations. Canyon Components also offers Aflas® and HNBR compounds for applications requiring amine or sour gas resistance, extending service life under particularly aggressive chemical conditions. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

High temperatures accelerate chemical attack and oxidation, especially in systems with strong acids or oxidizers. Many elastomers lose their elasticity or break down when exposed to continuous heat. Certain blends of Canyon Components’ Canrez FFKM materials are specifically designed for thermal stability over to 600°F while maintaining low compression set and excellent resilience. These materials maintain sealing properties through repeated thermal cycling, which is critical for processes such as polymerization, distillation, and acid production. For lower temperature requirements, our FKM and silicone compounds provide a balance of heat resistance and flexibility. By matching the compound to the temperature profile of the process, Canyon Components ensures consistent sealing force and extended maintenance intervals. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. Many chemical plants use complex mixtures of solvents, acids, and cleaning agents that challenge traditional seal materials. Canyon Components offers multi-resistant elastomers that retain stability in mixed chemical environments without volume swell or property loss. Our FFKM compounds resist both polar and nonpolar solvents, including acetone, MEK, toluene, and concentrated acids such as nitric or sulfuric. In addition, our FKM and EPDM materials are tested for compatibility with a wide range of cleaning and sterilizing agents, making them suitable for multi-purpose systems. Most compounds undergo chemical immersion testing to verify performance under extended exposure to mixed media. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Purity is critical in chemical and pharmaceutical production, where even microscopic contamination can compromise a batch or corrode metal surfaces. Canyon Components manufactures and packages its high-purity materials in controlled environments to prevent contamination by oils, mold release agents, or particulates. We also provide plasma-cleaned, parylene-coated, or PTFE-coated seals to minimize surface reactivity and friction. These coatings reduce sticking, ease installation, and prevent material transfer in reactive environments. For high-purity chemical or semiconductor-grade applications, seals can be cleanroom-packaged and vacuum-sealed, ensuring that they arrive ready for immediate integration into clean systems. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Designing for reliability requires careful attention to gland geometry, compression ratio, and surface finish. Over-compression can lead to early seal failure, while insufficient compression can cause leakage. Canyon Components provides design consultation to help customers optimize groove dimensions, sealing pressure, and material hardness for each application. We also offer back-up rings and anti-extrusion devices for high-pressure systems to maintain seal shape under load. Our engineering team can evaluate your operating environment to recommend the most effective configuration for both static and dynamic seals, reducing downtime and maintenance costs over the equipment’s lifespan. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Yes. Many chemical processing systems require seals or components with non-standard dimensions or profiles to fit unique assemblies. Canyon Components manufactures custom-molded O-rings, diaphragms, gaskets, and bonded assemblies in chemically resistant materials. Our production capabilities include compression, injection, and transfer molding, allowing us to achieve precise tolerances for both small prototypes and large production runs. We also produce metal-to-elastomer bonded components and multi-material assemblies for valves, pumps, and mixers, combining the chemical resistance of elastomers with the strength of metals or thermoplastics. All custom parts are validated through dimensional inspection and material testing to ensure long-term reliability. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!

Absolutely. Our sealing materials and compounds meet or exceed key industry standards including ASTM D2000, ISO 3601, NACE TM0297, NORSOK M-710, FDA CFR 21.177.2600, and UL 157. We provide full Certificates of Conformance, material test reports, and batch traceability for every shipment. For systems that require clean or sanitary operation, Canyon Components also supplies USP Class VI and FDA-compliant materials that are safe for contact with food or pharmaceuticals. Every product is backed by our in-house quality assurance process, ensuring full compliance and traceable verification of both physical and chemical properties. If you have any questions or require design assistance, feel free to reach out to the Canyon Components engineering team!
