Product details

The SuperPro O-440-9 is a replacement cover o-ring for diverter valves. It is listed as the cover seal for American 2 and 3 directional port valves, and also for Compool and Pac Fab port valve covers, the Polaris back up valve, Jandy valve covers and backwash valve covers and lids, and Waterway serviceable check valve and TruSeal covers.

Cover seal, not diverter seal

This is the o-ring that sits between the valve body and the cover you unscrew to get at the diverter. It is a different part from the seals on the diverter itself, so if the valve is passing water between ports rather than leaking to the outside, this is not the part you need.

The symptom it fixes

Water weeping out from under the valve cover. Once an o-ring hardens or takes a permanent set in its groove, no amount of tightening will stop the leak. Clean the groove and the mating face, fit the new o-ring with a thin film of silicone based lubricant, and tighten the cover down evenly.

Questions and answers

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

Which valves does this o-ring fit?
It is listed for American 2 and 3 directional port valves as the cover seal, and also for Compool and Pac Fab port valve covers, the Polaris back up valve, Jandy valve covers, backwash valve covers and lids, and Waterway serviceable check valve and TruSeal covers.
Is this the diverter seal or the cover seal?
The cover seal. It sits between the valve body and the cover you unscrew to reach the diverter. The diverter itself uses different seals.
My valve weeps around the cover, is this the fix?
That is the usual cause. A cover o-ring that has hardened or taken a set will weep under pressure no matter how tight the screws are.
Should I grease it?
A thin film of silicone based o-ring lubricant helps it seat and makes the cover easy to remove next time. Keep petroleum grease away from it.
