FEP/PFA Encapsulated O-Rings

The most versatile grade when considering overall corrosion resistance, sealing capability, and temperature. Operational temperature ranges from -450℉ to +400℉ (-267℃ to +205℃)

A fluorocarbon copolymer offering greatly improved mechanical and creep properties at elevated operating temperatures. Operational temperature ranges from -450℉ to +500℉ (-267C to +260C)

This fluoroelastomer combines exceptional mechanical properties and compression set resistance. This core has a Shore A hardness of 75 with a suggested operating temperature range of -10°F to +300°F (-23°C to +150°C).

This elastomer possesses mechanical properties similar to Viton®, with the exception of its slightly lower compression set resistance. It is more suitable for sensitive applications where lighter compressive forces are applied. This core has a Shore A hardness of 70 but offers a broad operating temperature range of -80°F to +500°F (-62°C to +260°C).

Hollow core O-rings provide effective sealing properties in applications where lower compressive forces may limit the sealing ability of standard O-rings. The combination of a hollow core with a slightly lower hardness offers a more flexible O-ring requiring less energy to activate its sealing capability.
