Product details

Pentair 273090 is the o-ring used on 2 inch push-pull valves, nominal 1-1/2 inch inside diameter with a 3/16 inch cross section. Two are required, so it is a part to buy as a pair.

Where it goes

A push-pull valve seals on the o-rings carried on its shaft. Pulling and pushing the handle drags those rings across the valve body every time the pool is backwashed, and over a season or two they flatten, glaze over and lose their squeeze. The valve then bypasses, which shows up as water going down the waste line while the system is set to filter, or as filtered water finding its way back to the pump.

Fitting

Replace both o-rings at the same time. Fitting one new and one old ring leaves the worn one to fail first and puts you back where you started. Lubricate the new rings with a pool grade silicone lubricant before assembly, not a petroleum grease, which swells the rubber.

Other valves

The same o-ring is also listed against the Sta-Rite 2 inch PVC slide multiport valve, models 261047 and 261165.

Questions and answers

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

How many o-rings does the valve need?
Two. The part is listed as 2 required, so replace the pair together rather than one at a time.
Does this listing include both o-rings?
The source does not state a pack quantity, only that the valve requires two. Check the quantity in your cart before you check out.
What size is it?
Nominal 1-1/2 inch inside diameter with a 3/16 inch cross section.
Why is my push-pull valve leaking past?
The shaft o-rings take the wear. When they flatten, harden or split, the valve passes water between positions even when it is pushed fully home, and new o-rings are the fix.
