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.
