Jabsco 59127-7004 Base Flapper Valve Gasket
The Jabsco 59127-7004 is a genuine replacement base flapper valve gasket for Jabsco 59128 series electric marine toilets. It seals the mating faces of two housing halves. Over time the sealing material takes a permanent compression set, hardens, or tears at a bolt hole, and the joint starts to weep instead of holding a dry seal.
It is supplied as a direct, drop-in replacement, made to the same material and dimensions as the original Jabsco part, so no fitting or modification is needed. Replacing it as a matched pair with its mating gasket or seal, rather than on its own, is the more reliable repair when the pump has been in service for several seasons.

Frequently Asked Questions
Q: Can I install this myself?
Yes. It is a like-for-like replacement for the original Jabsco part and needs no modification, though you should follow the torque and orientation of the part it replaces.
Q: Do you carry the rest of the service kit for this pump?
Yes, the related gaskets, seals and wear items for this pump family are stocked separately. Send us your pump data plate and we can point you to the full kit.
Q: Will this fit my pump?
It is the factory part for 59128 series toilets. If your pump carries a different model number, send us a picture of the data plate and we will confirm before you order.
Q: What else should I replace at the same time?
Since the pump is already open for this repair, inspect the nearby gasket, seal and fasteners and replace any that show wear so it does not need reopening soon after.
Not sure this is the right part? Send us a Picture of the Pump Plate on your pump and the CLR Marine team will confirm the correct gasket.
