Product details

This is the Pentair 39006600 diffuser gasket for American Products Ultra-Flow pool pumps, molded in rubber. It also appears under the references 2-231 and O-244.

What it seals

The diffuser sits over the impeller and directs water into the volute. The gasket between them is what stops water taking a short cut back around the diffuser instead of going out the discharge. A flattened or split gasket costs flow, and in a pump that struggles to hold prime it is one of the first cheap parts to rule out.

Rebuild part

Because it only comes out when the pump is already apart, most people fit a new one alongside the shaft seal and any o-rings rather than reusing a gasket that has already taken a set.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps does this fit?
Pentair American Products Ultra-Flow pumps.
Are 2-231 and O-244 the same gasket?
Yes. The gasket is listed under those references as well as the Pentair number 39006600.
What is it made of?
Rubber.
Should I replace it during a rebuild?
It is worth doing. Any gasket that has been compressed and heated for years does not seat the same way twice, and this one is inexpensive next to the labor of opening the pump again.
