Rubber Rings Manufacturer introduces PTFE O-type gaskets, including flat gaskets, V-shaped gaskets, piston rings, and ball valve gaskets that are mechanically turned or cut from PTFE rods, tubes, and plates. Has very good properties, such as conductivity.
The coating layer is mainly used for corrosion resistance and is usually made of polytetrafluoroethylene. The insert (filler) is a non-metallic sealing material with or without a metal reinforcement layer, usually an asbestos rubber sheet. According to different inner core structures, sealing gaskets are divided into V-shaped, U-shaped, and L-shaped. Petroleum, chemical industry, and certain containers, pipes, and valves in the industry are usually connected to high-temperature O-gaskets used for cleaning materials. The PTFE gasket has high mechanical strength and can be rotated. It has good performance and can be easily processed into various sealing products. The gasket will not cause the sealing stress to disappear due to the oxidation effect like graphite, and finally, lead to the sealing failure. It has a maximum temperature of 982°C (1800°F), which is very suitable for internal combustion engine exhaust systems, nitrogen fertilizer treatment, high-temperature steam generators, and many other high-temperature conditions.
PTFE gaskets are suitable for industries: chemical, petrochemical, oil refining, Chlor-alkali, acid, phosphate fertilizer, pharmaceuticals, organic synthesis, steel, atomic energy, and high-purity product manufacturing (such as ion exchange membrane electrolysis), transportation and operation of viscous materials, and Food and beverage processing and manufacturing sectors with strict hygiene requirements.
