Product details

The Pentair 272511 is the diverter shaft o-ring for PacFab top mount valves. It is the genuine Pentair part, listed with Sand Dollar sand filter parts and with PacFab top mount 1-1/2 inch valve parts for models 261124, 261130 and 262506.

The leak it fixes

The diverter shaft is the stem the handle turns to move between filter, backwash and the other positions. Where that shaft passes out of the valve body it is sealed by this o-ring. Over years of chlorine and handle movement the rubber hardens and takes a set, and water begins to weep or spray from around the handle whenever the pump runs.

Fitting

Work with the pump off and the system depressurized. Use a silicone based pool lubricant on the new o-ring so it slides into place without rolling or nicking on the shaft. If the valve is already apart, it is worth replacing the other seals in it at the same time.

Questions and answers

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

Where does this o-ring go?
On the diverter shaft, the stem the valve handle turns. It seals where that shaft passes through the valve body.
What does it fix?
Water weeping or spraying from around the valve handle while the pump runs. That leak path is the shaft seal.
Which valves and filters is it listed for?
Pentair PacFab Sand Dollar top mount sand filters and PacFab top mount 1-1/2 inch valves, listed against models 261124, 261130 and 262506.
Should I lubricate it?
Yes. A silicone based pool lubricant helps it slide into place without rolling or nicking, and it seals better seated properly.
