Product details

The Jandy R0446300 is the backplate o-ring used across the Jandy pump range. It is the genuine Jandy part.

What it seals

The back plate closes the rear of the wet end and carries the shaft seal. This o-ring is what keeps that joint tight. When it hardens and flattens, water weeps out at the seam and the pump can start to pull air on the suction side, which shows up as a low or unsteady water level in the strainer pot.

Which pumps

PlusHP PHPF and PHPM, MaxHP MHPM, Stealth SHPF and SHPM, ePump JEP variable speed, WaterFeature WFTR and WaterFall SWF series pumps.

Fitting

Clean the groove before the new ring goes in and give it a thin coat of silicone o-ring lubricant. That helps it seat evenly and stops it pinching as the housing is drawn back together.

Questions and answers

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

Which Jandy pumps use this o-ring?
The PlusHP PHPF and PHPM, MaxHP MHPM, Stealth SHPF and SHPM, ePump JEP variable speed, WaterFeature WFTR and WaterFall SWF series pumps.
Where does it sit in the pump?
Between the back plate and the pump housing. It is the seal for that joint, not the lid o-ring on top of the strainer pot.
Why does my pump leak at the back plate?
The o-ring hardens and takes a set over time, so the joint no longer closes. A fresh ring is the first thing to try.
Should I lubricate it?
Yes. A light coat of silicone based o-ring lubricant helps it seat evenly and stops it pinching as the housing goes back together.
