6 Pieces of Kinetic Wares 151122 O-Ring Compatible with Big Blue, Pentek and Pentair OEM Sizes

John M: They Fit! I have purchased several different O Rings for my Big Blue housing. Although most were acceptable, they were large enough that they did not fit neatly in the groove of the canister. These were exactly the right size and made installing the unit easy. Well worth the price. I just ordered a second set.

F. Lam: According to the specification listed, this O-ring is supposed to be good for both Pentek and AquaFlo Big Blue housing. I tried to install in the past weekend, and found that it was only good for the Pentek filter housing, but I have difficulty trying to use it on the AquaFlo 10" filter housing, as it kept leaking even with application of the silicone gel

Miker: This product is not the size as stated
They are too thin to seal my 20 inch big blue cannisters, so they won't seal and they leak. I twice requested a refund, but never heard back from them. I have nowrequested a formal refund via Amazon and now have to wait for 7 days to know if it is approved. Not recommended.

Ben S.: Changed the filter in my Big Blue 3/29/22. the existing O-ring had never been replaced through 10+years of filter changes. It was stretched enough to where it popped out of the groove. Wound up being a 1-hour struggle to get it back into the groove and tightened up.

Ordered these with PRIME one day delivery.

Items arrived as promised the next day. They come in a fairly sturdy zip bag. Knew the best course of action would be to replace old O-ring now and use new Oring because of the return time limits. (I get 12 - 16 months on each 20" filter)

For some reason the first try left unit with moderate leaking. So had to undo and reseat the O-ring. This time the magic happened and no leak.

The kit has 2 "ketchup packages" of lube. They are not resealable, so I used a binder clip to keep the package closed. The other 5 O-rings, the lubes and the pick are hung on a screw near the filter so will minimize the risk of losing the package.

Very much a good purchase, especially with it being 6 O-rings.

R.H.: Easy to see they are larger than the oem ones. Pentex 151122
I first I thought some cheap knock offs.
But I did finally install and try them. They are thicker / taller so they sit higher out of the groove. Is easier to take out since more rubber sits above the grove.
Hope they last and quality of rubber is as good as OEM. Time will tell. But being taller with more rubber they should end up being better with a actually better seal. Which would be my guess. And I do have quite a bit of general plumbing experience.
And should not even have to tighten as much as the oem ones for a good seal.
