PTFE Enveloped Steel Gaskets

Description

PTFE Encapsulated gaskets are FDA approved, pure virgin PTFE resin that is compression molded around and through a 304 stainless steel, perforated metal insert. After oven sintering, every gasket undergoes a 15,000-volt spark test to check for pinholes. The porous-free PTFE resin 100% encapsulates the stainless insert, isolating it from any fluid contact while in service.

PTFE encapsulated gaskets have a temperature range of cryogenic to 400°F and are chemically resistant to: all acids, all chlorides, all sulfates, all bleach solutions, all solvents, all phenols, all caustics, and all peroxides. PFTE encapsulated gaskets are leak-free and bubble-tight and can be used over and over without sacrificing sealing ability. These gaskets have zero corrosion rates which contribute to lower life-cycle costs when compared to envelope or solid gasket types.

The performance and longevity of PTFE encapsulated gaskets are unmatched. When installed between two flanges, the PTFE encapsulated metal insert restricts the PTFE from cold flow/creep while under load. The metal insert prevents radial flow of the gasket which eliminates bolt retorquing after installation, maintaining a tight seal even through repeated temperature cycles. The strength of the metal insert also provides critical, blowout-proof protection. Another benefit of these gaskets is the PTFE’s nonstick property which allows it to easily release from flanges during disassembly without any scraping.
