Kinetic Wares 151122 Oring Compatible with Big Blue, Pentek, Pentair O-Ring OEM Size 6 Pieces

My local well tech was impressed with the price.When I asked the company a question, the response quick and the clarity was GREAT.

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.

These o-rings are the right size for GE whole house water filter canister; as new o-rings, they fit perfectly into the seal groove. Other brands that I bought are too large and difficult to keep in the groove while fitting into place and tightening the canister.

Good price , good quality , good value.Good fit.

These were perfect replacements for the original O-rings in out Pentair Big Blue filters

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.

My big blue has no indication of manufacturer and was already at this property when I got it. I put i a new filter and of course the canister leaked. I took a shot on this product and it fit perfect and no more leaks. Its nice to have on hand. Of note in a previous review it states o-rong grease is included. It was not included in my kit. No problem, but be aware. I used petroleum jelly. I've not had issues using petroleum jelly on other o-ring in the past s I used it here as well. It is necessary to lube these so they stand up to torquing without deforming the o-ring.

Try to use it for my big blue but it too narrow.

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

Was getting quoted $110 for one of these and got 6 for a fraction of the price, so so happy, thank you so so much, now hope it doesn't leak

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.
