Product details

The Pentair 154005 is the genuine spacer o-ring for Triton C-3 side mount sand filters. It measures 4 1/8 inches on the outside diameter and 3 3/4 inches on the inside.

Two are required

The filter uses a pair of these o-rings. This listing covers one, so order two to do the job properly. Replacing only the one that failed almost always means opening the filter again before long, because both have spent the same years in the same conditions.

Before you fit it

Wipe the groove clean and check the sealing face for grit or scale. A new o-ring on a dirty seat still leaks, and the seat is easy to clean while the filter is apart.

Questions and answers

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

How many do I need?
Two. The filter calls for a pair of these spacer o-rings, and this listing is for a single o-ring.
What size is it?
4 1/8 inch outside diameter and 3 3/4 inch inside diameter.
Which filter does it fit?
It is listed for the Pentair Triton C-3 side mount sand filter.
Should I replace both at once?
Yes. Both o-rings age at the same rate, so changing only the one that leaked usually means going back in a season later for the other.
