Product details

Jacuzzi 47038047R is the OEM tank o-ring for Sherlock filters. It seals the joint between the two halves of the filter tank, which is the one place on a filter that has to hold pressure every minute the pump runs.

Sizing

The ring measures 11-3/4" across the outside, 11-3/8" across the inside, and 3/16" thick, in rubber. Those three numbers matter more than they look: an o-ring a fraction too thin will not fill the groove under clamp load, and one a fraction too large rolls out of the groove as the tank closes.

When to replace it

Water weeping from the tank seam is the classic symptom. Rubber that has gone hard, taken a flat set in the groove, or picked up a nick from a screwdriver will not seal again however tight the clamp is drawn, and overtightening to chase the leak only damages the clamp. Fit a fresh ring instead, and make a habit of replacing it whenever the tank is opened for a filter service.

Questions and answers

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

What size is this o-ring?
It measures 11-3/4" on the outside diameter, 11-3/8" on the inside diameter, and 3/16" thick.
Which filter does it fit?
It is the OEM tank o-ring for Jacuzzi Sherlock filters, Jacuzzi part 47038047R.
My filter drips at the seam after cleaning. Is this the fix?
Usually. Once the o-ring takes a permanent set or picks up a nick, it will not seal again no matter how tight the clamp goes, and a new ring is the correct repair.
Do I get more than one?
No. This is a single o-ring, not a seal kit.
