OMNIFilterOK25-S6-05 O-ring OK25,6 count(pack of 1)

Package included 2 rings, one 1/4 inch and one thicker which I didn’t measure. Both are slightly larger in circumference than the o-ring groove which I measured at 5-3/4 inches.I sat the thicker one on top of the edge of the filter base and just screwed the lid down tight and it sealed. It’ll be a miracle if it doesn’t leak eventually but it’s not worth returning.I’m offgrid and using a demand pump.

Bought the rings 2 years ago. On last filter change I had to reuse the ones I was using for 12 years, because the 4 different ones I bought at the time were too thin and would not seal. So I bought these and the biggest one still looks a micron too narrow but it is not leaking, however the second ring in the package is a completely different thickness and is unusable. Arrgh.

I had to measure the gasket thickness with a Vernier caliper to find the right one to fit the OMNIFilter OT-32, but installation was quick and easy.Package contains 4 different-sized gaskets and 1 small tube of medical-grade silicone lube.You will need TWO (2) packages for the Dual-Cartridge OMNIFilter OT-32. I knocked off 1 star because I had to buy 8 gaskets to get the 2 that were needed.

What a waste of money you buy this kit with all these gaskets in and you can only use one out of gaskets. I have at twin set up so I have to buy two of these kits so I throw away most of the gaskets which I couldn't use on anything else.

The picture shows 2 blue and 2 black "O" Rings. But the factory package contains 1 blue 2 black of the same size and 1 black larger "O" Ring. And of course I needed 2 blue "O" Rings for my Omni Filter. I called and the vendor made good on it and shipped another kit, but the 2nd pacakge contained exactly the same thing, so I have to assume the factory has changed what it includes in the kit. 4 stars is a balance between the package being incorrect, but excellent CS from the vendor.

I bought these for my well water cleaner.

The way this product is packaged is actually misleading. The product comes with two o-rings, one fits the BF7, and the other fits the BF35 housing. So if you don't have a BF7 and BF35 housing, then you're only going to get use out of one o-ring. It's a waste of money to buy two o-rings and have to throw the other one away.

My dad needed an OK25 ring when he changed the filter on the fridge this piece that was 20 years old broke off. He asked me to order one prime & it shipped in time for him to sell the house. He said it worked perfect.

They do not fit. The circumference is off.

Of the 5 rings in the package, only 1 fits the OK25 filter and the size measurement listed in the description.
