Contoured Back-Up Rings | FKM Viton® 90
FKM Viton® 90 Contoured Back-Up Rings are designed to support O-Rings in high-pressure, high-temperature, and chemically aggressive sealing applications. Molded from 90 durometer FKM, these contoured back-ups provide the stiffness needed to prevent O-Ring extrusion while retaining enough elasticity to stretch over piston diameters and snap cleanly into the gland groove. Viton® offers excellent resistance to heat, fuels, oils, solvents, and harsh chemicals, making these back-up rings a strong choice for demanding hydraulic and pneumatic systems where failure is not an option.
