Teflon® (PTFE) Encapsulated FKM (Viton®) O-Rings

PTFE (Teflon) Encapsulated FKM (Viton®) is known for long service life in aggressive chemical duty with a non-stick sealing surface that resists fouling and leakage. Expect good resistance to steam, nearly all process chemicals, and strong acids and solvents. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). It is not the right choice where service requiring tight-radius dynamic flexing. It's also important to note that installation over sharp edges should be done with care as not to damage it.
