Meet Your Most Critical Sealing Application Needs

Encapsulated O-rings are regularly used in the semiconductor industry and other high-performance applications due to their specialized sealing properties.

These O-rings consist of a traditional O-ring made from a resilient elastomer, like silicone, fluoroelastomer, or ethylene propylene diene monomer (EPDM), that is encapsulated within a thin layer of fluorinated ethylene propylene (FEP) or perfluoroalkoxy (PFA) fluoropolymer.

These sealing solutions are ideal for applications where purity, chemical resistance, and reliability are critical. Talk to North Coast Seal about how we can meet your needs.

Encapsulated O-Ring Materials

Excellent Sealing Properties With FKM, EPDM, and More

The core of an encapsulated O-ring is made from elastomers with superior sealing capabilities. Common core materials are silicone, fluoroelastomers (FKM), and EPDM—the choice of material depends on temperature, chemical compatibility, application requirements, and other factors. The encapsulated layer is made from FEP or PFA fluoropolymers.

Encapsulation provides exceptional resistance to a wide range of aggressive chemicals, which protects the core O-ring material and extends the life of the seal in corrosive environments. Encapsulated O-rings can contribute to increased process efficiency, reduced contamination risks, and improved product quality: They will benefit your semiconductor manufacturing applications.
