CAZ PE670 PTFE Envelope Gasket consists of rubber-asbestos, non-asbestos, rubber, corrugated stainless steel etc. cushion material encased in PTFE envelope, resulting in a gasket with the excellent corrosion resistance of PTFE and the strength and resilience of core material. It can be produced in several types to meet the most demanding applications.
670V-- V type, Slit in center from outside, An economical solution for lower pressure applications.
670L-- L type, Cut PTFE into square form, For use with medium and higher pressure.
670U-- U type, Heated & welded at one joint, Normal for DN≥200mm.
◆Virtually 100% chemically resistant.
◆Temperature range from- 200~+250oC depending on the core.
◆Mechanical strength dependent on core selection.
◆Pressure≤4 Mpa
