FEP-/PFA-encapsulated O-rings combine the excellent chemical resistance of PTFE with the elastic behavior of an elastomer.
They are a top choice when the rubber-elastic quality of the seal is indispensable, but the application also requires better chemical resistance than traditional elastomers. The Gallagher Engineering Department can determine if an FEP-/PFA-encapsulated O-ring is right for your specific application.
In this blog post, our partners at Freudenberg Sealing Technologies outline some of the advantages of encapsulated O-rings.
