Overview

Envelope gaskets

Envelope gaskets are made from PTFE and are built around the choice of an EPDM or FKM rubber core, improving the gaskets sealing characteristics. They are designed to achieve a smooth bore, contamination free fluid path under clamping compression.

These sanitary gaskets can be exposed to temperature extremes from -212 ºC to 232 ºC (-350 ºF to 450 ºF) and come in a range of sizes from ½ inch to 6 inches.
