Description

This is the exact replacement – Leybold part 23953124. It is made of tough Viton rubber. Viton stands up to hot oil, chemicals and long running times much better than ordinary rubber.

Changing it is not hard. During a repair you take out the old seal, clean the housing, and press the new one . Most people do it with a socket or a simple seal driver.
