Oil seals have a flexible lip that rubs against a shaft or housing to prevent the leakage not only of lubricants, but also water, chemicals, and gas from equipment. Oil seals also serve to prevent the intrusion of dust, soil and sand from the outside air.
Oil seals are indispensable sealing devices and are used in various fields, including automobiles, aircraft, boats and ships, railroad vehicles, construction machinery, farm machinery, petrochemical plants, and electrical home appliances.
The most important consideration of oil seal is the elastomer material. We will help with selection by considering the working conditions and the functions of the seal as following:
– Good chemical resistance
– Good resistance to heat and low temperature
– Good resistance to ozone and weathering
– High resistance to water
– Low compression set
– Good elasticity
