6. Ensure that the oil seal solidifies
Oil seals are made out of nitrile synthetic rubber with steel stiffener rings. Other rubbers such as viton, silicon, neoprene or poly acrylic can be used for specific applications. The stiffener rings may be stainless steel or brass where highly corrosive fluids are to be sealed. Springs are generally made of spring steel to IS: 4454:Gr.ll or from stainless steel or bronze for corrosion resistance


A wide range of sealing devices are used in various machines.
Sealing devices serve the following functions:
(peripheral speed)


d1, mm
When installed, the oil seal’s flexible lip is placed against the rotating shaft, and the casing is pushed into the housing for support. It is crucial that the sealing lip is lubricated to avoid overheating caused by friction.
Oil seals are used for essential applications in the oil, gas and petrochemical sectors. They are created to avoid leaks from the sealing lip and rotary shaft by forming a thin layer of oil between them. Oil seals could be developed using well-known sealing materials, involving NBR, EPDM, PolyTetraFluoroEthylene (PTFE), Silicone,and fluoroelastomer.
