- For the Ultra-Flo pump Fits the Pentair American Products Ultra-Flo pool pump.
- Rubber seal Supplied in rubber, matching the original.
- Seals the volute Keeps the pump housing sealed so the pump holds prime and does not weep.
- Fit it during a rebuild Anytime the pump is opened far enough to reach the volute, the o-ring is worth replacing while you are in there.
- Cheap fix for a fussy pump A flattened or nicked o-ring pulls air, and an air leak reads on the gauge as a pump that will not prime.

Product details
The Pentair 39006000 is the volute o-ring for the American Products Ultra-Flo pool pump. It is the genuine Pentair part, in rubber.
What the volute o-ring seals
The volute is the housing that surrounds the impeller and directs water out of the pump. Its o-ring keeps that joint sealed. Because the pump is under suction on the intake side, a seal that has flattened, hardened or picked up a nick lets air in rather than water out, and the symptom an owner sees is a pump that struggles to prime, holds air in the basket or runs noisily.
Replace it while you are in there
Getting to the volute means the pump is already apart. That is the moment to fit a fresh o-ring, along with any other seals in the kit, rather than reusing an old one and opening the pump again in a month.
