What is FEP Encapsulated O Ring?
PTFE FEP O RING combines the rubber's elasticity and scalability with the chemical resistance of Teflon.
It is composed of a silicone or fluoroelastomer core and a relatively thin Teflon FEP (polytetrafluoroethylene).
This is a combination of propylene or Teflon FPA (soluble Teflon) outer covering. This rubber Teflon seal has excellent sealing properties.
Rubber O-rings are subject to wear, chemical and gas-permeability resistances, and the high hardness of pure Teflon O-rings can give compression but poor elasticity.
The friction coefficient of the outer cover Teflon FEP/Teflon FPA is very small (only 0.1~0.2), and it has excellent resistance to gas permeability.
These properties make the sealing ring can really be used in harsh environments.
The PTFE-coated O-ring replaces the Australian-based perfluoro elastomer O-ring.
