Tetrafluoroethylene non-standard sealing gasket:

Select suspension polymerization teflon It is made of resin molding. Compared with other plastics, it has excellent chemical corrosion resistance and temperature resistance, and has been widely used as

Sealing material.

RF type gasket has no screw hole and is tightly installed on the flange face inside the screw hole.

The outer diameter of FF type gasket is the same as the outer diameter of flange and has correct screw holes.  

As a sealing material, polytetrafluoroethylene has many applications. Because of its high corrosion resistance, stable physical performance, high and low temperature resistance, it has achieved good sealing performance and has been widely used in the petroleum, chemical, pharmaceutical, power, and steel industries. Applicable media include water, oil, acid solution, alkali solution and almost all chemical components. Polytetrafluoroethylene is a macromolecular compound polymerized from tetrafluoroethylene, which has excellent chemical stability and corrosion resistance (it is one of the materials with good corrosion resistance in the world today. It can resist all other chemicals except molten metal sodium and liquid fluorine, and it does not change when boiled in aqua regia, and is widely used in various conditions requiring acid, alkali and organic solvent resistance), sealing High lubrication, non viscosity, electrical insulation, good anti lao property and large temperature resistance span. Its birth has solved many problems in the world's chemical, petroleum, pharmaceutical and other fields. It has been widely used as sealing material and filling material.
