FEP-/PFA-Encapsulated O-Rings – Elastic & Highly Chemically Resistant
Ideal for Chemistry, Pharma, and Food – Seamless, Reliable, Versatile
FEP- or PFA-encapsulated O-rings combine the elasticity of cores made from FKM, VMQ, or EPDM with the high chemical resistance of a seamless FEP or PFA jacket. The encapsulation protects against almost all common chemicals, making these seals the ideal choice for sensitive processes. They are used in industries such as chemical, pharmaceutical, and food technology. We offer numerous standard dimensions as well as special sizes with cord diameters from 1.5 to 31.7 mm – precisely tailored to your application.
