Pentair87300400 Body O-Ring Replacement Pool and Spa Filter

fits well

This came with a set of two but only needed one for my pentair filter. It was a snug fit but did work and solved the leaks that were coming from my old worn gasket.

Fixed my leaky filter.

Works well

This "O" ring is good quality and works well. Be sure to lubricate it well and it will seal just fine.

Great item, price and excellent delivery time. Thanks

Exactly as ordered, on time, great quality

This item is offered as a Pentair 87300400 Body O-Ring “Genuine Pentair Brand replacement part”. It is not.I am dubious of the high rating this item received. This o-ring does not work with the Pentair Clean & Clear 150 filter unit. Despite a generous application of Tube Lube on the o-ring and inside the cover, it was impossible to get the cover back on. We tried with two of us pushing down on the cover at the same time; we tried standing on a stool for more leverage to push down, and we even tried to get the cover on using a rubber mallet. The results were always the same - one side would slide over the o-ring, but the opposite side would not. Some of the reviewers mentioned it would be hard getting the cover back on so we kept trying without success. Finally, feeling defeated we gave up. I did not realize until later that my partner picked up another o-ring (*real* Pentair OEM part) when getting the lube from the pool store. As you can see from the photos, the packages are quite different. Compared side-to-side, this o-ring is noticeably larger than the Pentair version. When this o-ring was replaced with the Pentair version, the cover was quickly and easily placed and secured with the Locking Ring.Photos Attached: 1.) this o-ring item is packaged in a generic, unbranded, package. A Pentair barcode sticker, affixed to the package, covers some of the text; the word "Generic" is visible; 2.) full text under the barcode sticker; 3.) side-by-side comparison of this o-ring item package vs. an actual OEM Pentair o-ring package.
