The
FEP/PFA Encapsulated o-rings are double-action sealing elements. The seal is provided by the FEP or PFA encapsulation; whereas,
the elastomer o-ring (fluorocarbon rubber, silicone, etc.), serves as an elastic pretension element exerting a permanent and uniform pressure against the mating surface. The FEP or PFA "jacket" encases the elastomer o-ring without seams.
The most important advantages of o-rings with FEP or PFA encapsulation as compared to conventional o-rings include:
- low friction, no stick slip effect, no adhesion tendency
- very good chemical resistance, compatible with most fluids and chemicals
- no contamination when used with food, pharmaceutical and medical products
- physiologically harmless, can be sterilized
- low steam permeability
- wide temperature ranges (varies based on o-ring compound)
