Jabsco 18753-0340 O-Ring for Cam Screw
The Jabsco 18753-0340 is a genuine Jabsco O-ring for the cam screw. It seals the cam screw where it passes through the pump body so the pump does not leak or draw air at that point. 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.
O-rings seal the joints between fixed parts of the pump. Once an O-ring has been compressed in service it takes a set and may not reseal, so fit a new one whenever the joint is opened. Check the groove is clean and undamaged, lubricate the O-ring lightly with a grease that suits the material, and make sure it is not twisted or pinched as the parts come together.

Frequently Asked Questions
Q: Why does a new O-ring still leak?
Check for a damaged groove, dirt on the sealing faces, or an O-ring that was twisted or pinched on assembly.
Q: Should I keep spares?
Yes. O-rings are small, inexpensive and easy to lose during a rebuild.
Q: Can I reuse the old O-ring?
It is not recommended. A used O-ring has taken a set and often leaks when the joint is reassembled.
Q: Should I lubricate it?
Yes, lightly, with a grease that is compatible with the O-ring material and the liquid being pumped.
