720*680*20 720-680-20 720x680x20 L2 FKM Oil Seal

1.Product Description:

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.

How do Oil seals work?

The common radial oil seals work by creating a thin layer of oil between the rubber sealing lip and the shaft which results in the oil lifting the sealing lip clear of the shaft. This thin layer of oil performs a barrier and prevents leakage of the oil past the sealing lip.
