FEP Encapsulated O-Rings are ideal in static applications, but in many situations have also been used in dynamic applications like mechanical seals. In dynamic applications they do have good wear resistance. FEP O-Rings are FDA Compliant which can take Pressure in Vacuum application upto 10,000 psi
FEP Encapsulated O-Rings are coated with a sleeve of FEP which protected from chemical attack. The core is generally Viton or Silicone, which gives the o-ring the ability to recover it's shape after it has been compressed. Silicone cores are generally used in low temperature applications to -24°F. Viton has better compression set characteristics and is recommended in applications with constant temperature to +200°C .
FEP Encapsulated O-Rings are available in metric and imperial international standards sizes such as as AS568 , DIN ISO 3601 and JIS sizes , thus providing the quality assurance required to meet the world's most demanding applications of O-Rings
O-rings are made on order in wide range of materials: Nitrile (NBR), Viton (FKM), Silicone (VMQ), Neoprene (CR), Ethylene-propylene (EPM/EPDM), Polytetrafluoroethylene (PTFE)
