The o rings were the perfect size and fit. The only thing I would say is that it shows a box in the picture and they didn't come on a box. Also when I removed them from the plastic bag they were all stuck together. It wasn't much of a problem.

I have no idea what kind of filter we have, but it's definitely an old one! We've lived here for over a decade and it was here when we moved in. The filter started leaking and after some research I found that the O-Ring actually needs to be replaced from time to time. So, I bought these. They were cheap, and I figured if they didn't work I could find some other purpose for them. They work absolutely perfectly, though! It took less than 5 minutes to install them (and most of that time was spent trying to get the filter off in the first place), and no leaks since.

I ordered to fit an OmniFilter o-ring. Too smal, had to order from the factory. They look like they’ll work for something.

IF I COULD LEAVE A ZERO RATING I WOULD...These o-rings were purchased as a direct replacement for pentek 151120. These o-rings are supposed to fit inside a water filter cartridge housing. The company labeling says they are a direct replacement. Absolutely wrong...they are too thick and the circumference is smaller than the correct pentek o-ring. So, i attempted to make this so called direct replacement o-ring work and it caused water to spray all over the basement wall and floor because it was too small and bunched in the threads. I had to drive to a local water softener dealer to buy the correct o-rings. This is the problem with online sellers...no knowledge, inaccurately labeled products and waste of time when it is marketed as direct replacement. No one should ever buy this brand or seller. You will never know if you are getting the right product until it is too late. Then you are without water in your house until you can find the CORRECT replacement.

My two stage fresh water filter system was leaking so I decided to replace the o rings. These were a perfect fit and the problem was solved! No more leaks!
