Silicone Core FEP-Encapsulated O-Rings (FDA compliant)
A specialty sealing solution designed for food, beverage, pharmaceutical, and chemical processing applications where extreme chemical resistance and product purity are critical. These O-rings combine an FDA-grade silicone core for elasticity with an FDA-compliant FEP fluoropolymer encapsulation, so the process fluid only contacts the chemically inert FEP surface.
In real-world use, Silicone core FEP-encapsulated O-rings excel in pumps, valves, fittings, and transfer systems exposed to aggressive chemicals, solvents, acids, and repeated CIP cleaning cycles. The FEP jacket delivers PTFE-like chemical resistance and cleanliness, while the silicone core provides better compression and sealing force than solid PTFE seals, reducing leaks and improving reliability.
They are an excellent choice when chemical compatibility, cleanability, and FDA food contact compliance matter together, especially in applications where standard elastomers cannot survive and full FFKM performance is not required.
