Product details

Pentair 354053 is the valve top o-ring for PacFab filter valves. It measures 6" outside diameter, 5 5/8" inside diameter and 3/16" thick. It is the genuine Pentair part.

What it seals

This is the o-ring that sits between the valve top and the valve body. Every time the top comes off for rotor or spider gasket work, this seal is disturbed, and it takes a permanent set against the surfaces it has been clamped to for years.

Fitment

It is used on the PacFab 6-way 1-1/2 in. Hi-Flo multiport valve in models 261124, 261130 and 262506, and it is listed with the PacFab Sand Dollar SD35, SD40 and SD60 sand filters. Measure the old ring against the dimensions above if you are unsure which valve you have.

While you are in there

The spider gasket and the rotor assembly are the other wear items behind the same valve top, so it is worth looking at both before closing the valve back up.
