Product Introduction
HS855 PTFE coated gasket is made of turning PTFE as the coating material, lined with non-asbestos synthetic fiber, fluorine rubber, nitrile rubber, EPDM rubber and other soft materials, combined with the excellent corrosion resistance of PTFE and the good compression and rebound compensation performance of the lining material, reducing the required bolt pre-tightening pressure. It is an economical sealing gasket. It is mainly suitable for sealing flanges of pressure vessels with large diameter (such as heat exchangers, reactors, cast iron flanges, cylinder heads, boilers, etc.). All kinds of media pump, pipe valve, pipe and all kinds of equipment flange seal. Suitable for medium and low pressure conditions.
