ASME B16.21 PTFE Envelope Ss Asbestos Free Ss Corrugated Rubber Gasket

SpecificationsPTFE enveloped non asbestos gasket speical kinds ptfe gasket, use for clean condition sealingPolytetrafluoroethylene (PTFE) envelope gaskets provide excellent sealing in corrosive environments. Combining the low friction and chemical stability of PTFE with the mechanical strength of the gasket material, GINSEAL PTFE envelope gasket provides the user with a gasket that can be used confidently with aggressive media which would attack many other materials.Temperature:Up to +250oC (depending on the gasket material used).Applications:Glass lined pipe systems, distillation columns and reactor vessels whereNon-contamination is essential.GINSEAL PTFE envelope gaskets are available slit (v-type) or milled (square cut) with a variety of materials available for fillers.Type AItem No.: JSG-PT31Made in the material forming a "V" shape space for one filler. The pointOf the "V" protrudes slightly into the pipe causing slight flow turbulence.Type B& CItem No.: JSG-PT32 & JSG-PT33Material is milled or machined out between leaves to form a U or squareShaped space for the filler. The filler is flush with the envelope which isFlush with the pipe, permitting free flow.Larger size is also available. (Folded envelope)Material:Material for filler: Non-asbestos, EPDM, reinforced graphite, etc.
