Jabsco 1189-0000 End Cover Gasket
The Jabsco 1189-0000 is a genuine replacement end cover gasket for Jabsco flexible impeller pumps. It seals the end cover to the front of the pump body so the pump holds its prime and does not weep, and its thickness is part of the internal clearance between the end cover and the impeller, which is why the factory gasket should be used rather than one cut from sheet material. It is listed for Jabsco 2760 series bronze pedestal pumps.
Gaskets compress in service and take the shape of the cover they were fitted to, so a used gasket rarely seals a second time. Fit a new one every time the end cover comes off for an impeller change, and clean both faces completely before fitting it.

Frequently Asked Questions
Q: Can I reuse the old gasket?
It is not recommended. A used gasket has taken a set and will often leak or let the pump draw air when refitted.
Q: Should I use sealant on the gasket?
No. The gasket is designed to seal dry against clean faces. Sealant can squeeze into the pump chamber and change the clearance.
Q: Why is my pump losing prime after an impeller change?
An old or pinched gasket is a common cause. Air drawn in at the end cover stops the pump from pulling a vacuum on the suction side.
Q: Can I cut a gasket from sheet material?
Only as a temporary repair. The factory gasket thickness is part of the impeller end clearance, and the wrong thickness costs output or wears the impeller.
