Good To Know

Q: Does this seal fit both the impeller shaft and the pump housing bore? A: It is sized for the original impeller shaft oil seal location, so it seats into the standard bore on compatible models. Confirm against your machine before ordering.

Q: Can I reuse the old seal if it looks intact? A: Oil seals are wear items and are best replaced once removed, since the lip and spring can deform. Replacing it during pump service helps avoid repeat disassembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
