Quick overview
- Genuine Pentair Factory part 072431Z, matched to the valve it seals.
- For 2 inch valves This is the 2 inch seal. The 1-1/2 inch valve takes a different Pentair seal.
- Positive diverter The seal that lets the diverter shut a port off rather than merely favor one side.
- Stops crossover A worn seal lets water past the diverter, so a port you thought was closed keeps flowing.
- Part of a valve service Worth changing alongside the valve o-rings while the valve is open.
- Seal only The diverter, shaft, cover and o-rings are separate parts.

Product details
The Pentair 072431Z is the positive diverter seal for 2 inch diverter valves. It is the genuine Pentair part.
What the seal does
A positive diverter is meant to close a port outright, not just bias flow toward one side. The seal is what makes that possible: it presses against the valve body so the shut side is genuinely shut. As the seal hardens with age and chemical exposure, water finds its way past, and a port that reads closed at the handle is still passing flow. That shows up as a spa that will not hold its return, or a suction line that keeps pulling when it should be isolated.
Before you order
Confirm the valve size. This is the 2 inch seal, and the 1-1/2 inch valve uses a different Pentair part. While the valve is apart it is worth looking at the shaft and the cover o-rings, since a valve that has been stiff to turn has usually taken its wear in more than one place.
