O Ring Viton
O-rings are mainly used for static clearance sealing of fluids (such as water, oil, air, chemical solvents, chemicals, etc.) The long-term service temperature is - 60 ℃ to 220 ℃. Depending on the material, the static service pressure is less than 20MPa. Sometimes it can also be used for dynamic, and the service pressure in dynamic is less than 5MPa. And semiconductor vacuum seal. The commonly used materials are: nitrile rubber, silicone rubber, fluororubber, EPDM fluororubber. The service temperature is minus 20 ° to 250 °, which has good heat resistance, excellent oil resistance and chemical resistance. Among all kinds of rubber, the oil seal has the material with the best rubber performance balance.
There are more than 5000 models of fluororubber materials, with sufficient inventory:
