DMAG Best Quality NBR Oil Seal for Industry Use


An oil seal is a mechanical seal that is fitted in the space between two mating surfaces to create a seal. It is used for sealing and maintaining a desired pressure or vacuum.

The oil seal has been around since the late 1800s, when it was invented by Alanson Crane. It was initially used in industry and machinery but has now found its way into other applications like home appliances, automobiles, and even medical equipment.

The main function of an oil seal is to provide a barrier between two moving parts of machinery that are under pressure so that they do not leak or damage each other.
