PTFE Envelope Gasket

PTFE Envelope Gasket

These gaskets are successfully used in chemical plants, glass lined equipment due to their high temperature, corrosion and ageing resistance. Envelope Gaskets are produced in two forms : - Milled and Slit forms. Milled type envelope is perhaps the better of the two since it is made it fit the insert and present a flat face to the flange. The slit type is perfectly arrogated for many applications where cost is a major consideration. The envelope in this variety does not present a full face to the flange. Solid gaskets can be made to order in different types of shapes and sizes.
