Pentair 35505-1275 O-Ring Cover Replacement for Sta-Rite 1-1/2-Inch Multiport Pool and Spa Valves

I used this to replace the gasket between the two halves of the multi-port valve on an ancient Sta-Rite Cristal-Flo model T-240BP-1 Sand Filter. The old gasket had begun leaking. This one fit perfectly and after 3 weeks there are no leaks. I was a little concerned as the old gasket had compressed to the point that it looked like it had a flat top, so I was thinking maybe a round gasket was not going to be what I needed, but when I actually removed the old gasket I could see that while the top and bottom had become flat, it clearly had originally been a round gasket like this one.

Replacement for my Sta-Rite multiport valve WC112-148A part 35505-1275 O-Ring. The valve is used on model T-240BP-1 sand filter.

Perfect fit. I had to remove the upper valve from the unit and while the 12 year old o-ring looked to be in good shape, I did not want to tear the unit down again. Its working flawlessly since replacement.

Fast shipping good product

100% recomended

It's an old ring people

Works as expected.

Perfect fit for my Sta Rite filter. Not much else to say about an oring. It either fits or it doesn't.
