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 1201, although higher in cost, is machined to provide unobstructed media flow necessary in high pressure, high flow applications. Our inventory includes Style 1201 envelopes for standard flange sizes to 20", and in special sizes as well.
