Oil seal is mainly used to seal media with pressure. It has advantages when sealing low viscosity and gaseous media.

TC type oil seal is double lip (one main lip and one auxiliary lip), one spring, and the steel framework is completely wrapped by rubber. It is used in the situation of low pressure, one side has sealing medium and the other side has slight dust. The maximum pressure is 0.03mpa (0.3kgf / cm2).

Nitrile rubber seals, with a service temperature of minus 40 ° to 125 °, is resistant to mineral oil and has good wear resistance. It is most used in oil seals, but it cannot be used in ketone and lipid polar solvents.

There are more than 5000 models of nitrile rubber (NBR) tc nbr oil seals, with sufficient inventory:
