PTFE Protected Gaskets
Style 1200 - PTFE Envelopes - Split Type
The use of PTFE envelopes provides maximum economy for sealing all acid and caustic media pH 0-14, with most gasket material being able to be utilized as a filler gasket. Removal of used PTFE envelopes is easily accomplished due to the non-stick properties of PTFE. These envelopes are available with or without filler gaskets. Special fillers for glass or ceramic lined pipes are also available
Style 1200, being more economic, is an ideally suited gasket for standard pipe flanges locating itself within the bolt circle. Our inventory includes Style 1200 envelopes for standard flange sizes to 20", and in special sizes as well.
