Jabsco 18753-0630 Oil Lip Seal
The Jabsco 18753-0630 is a genuine Jabsco oil lip seal, which keeps oil in and dirt out where the shaft leaves an oil lubricated housing. Jabsco uses this part number on specific models only, so match it against the parts list for the model number on your pump plate before ordering.
Lip seals ride on the turning shaft to keep liquid in and dirt or water out of the bearings. A worn lip lets water reach the bearings, which then fail quickly. Replace lip seals whenever the pump is rebuilt, fit them facing the right way, and check the shaft surface where the lip runs for wear grooves.

Frequently Asked Questions
Q: Which way does the lip face?
The lip normally faces the liquid it is holding back. Note the direction of the old seal before removing it.
Q: Should I replace the bearings at the same time?
Check them. If water has got past the seal, the bearings are often already damaged.
Q: Why does a new seal leak?
A worn groove on the shaft where the old lip ran is the usual cause.
Q: Should I lubricate the lip?
Yes, a light film of compatible grease helps it seat without damage.
