Product Details

Chemical Resistant Encapsulated FKM O-ring

Silicone or fkm O-Rings encapsulated with FEP or PFA are designed to address the growing problem of sealing in the most hostile chemical and temperature environments. FEP or PFA on the outside with its chemical inertness and an elastomer on the inside for resilience. This unique combination forms a highly effective, long lasting seal for the most demanding applications. Encapsulated O-Rings are primarily used as a static seal (axial or radial).
