PTFE is a superior O-Ring material not affected by most chemicals.
It can be used at temperatures up to 500°F (260°C). It has the
lowest coefficient of friction of any solid material. Lubrication
is less critical and can sometimes be omitted.
O-rings can be made 100% from PTFE or elastomers silicone or
nitrile can be coated in a PTFE sheath for added chemical
resistance while maintaining maximum flexibility.
