Our ProductsFEP O-rings

FEP-coated O-rings have an elastic core of Viton® or silicone (Si). The respective Viton® or silicone O-ring is seamlessly enclosed by a thin-walled jacket made of FEP. The thickness of the FEP jacket depends on the inner diameter of the sealing ring and its cord thickness. These properties result in new additional application possibilities for the FEP-coated O-ring. While the O-ring made of silicone or Viton® is used to achieve the required elasticity, the FEP jacket ensures high chemical resistance of the sealing ring. The typical applications for the FEP-coated O-ring are in the chemical, petrochemical, pharmaceutical and food industries.

 

FEP-coated O-rings are available with a Viton® or silicone core. Basically all dimensions are available in the range 1,5-19,0mm cord thickness. The following rings are preferred as standard:
