Shaft Seal, 20x42x7 – Part # 907001 – vacstellar

Description

This is a  replacement shaft seal, part number 907001. It measures 20 mm inside diameter, 42 mm outside diameter, and is 7 mm thick. This seal fits around the drive shaft where it enters the pump housing. It keeps oil from leaking out and prevents air from leaking in. If you see oil dripping from the shaft area, this is the part you need. This shaft seal has specific dimensions: 20 mm inside diameter, 42 mm outside diameter, and 7 mm thickness. Using the correct size is very important. If the seal is too loose, it will leak. If it is too tight, it can damage the shaft or cause the pump to run hot. This part is made to fit exactly where it is needed.
