Great kit for water filters.
Used this to replace the O-Ring in an Omnifilter. Worked perfect. No more leaks!

The O-Ring Worked!!!!!!!
I was a little disappointed that the package contained 8 O-Rings, and only 2 in the package were applicable to my water filter (Omni-Filter CBF1). So, I have 6 that are relatively useless. But, the O-Ring I needed worked and stopped the leak! Awesome! I don't mind having extras I can't use, so long as what was sent did work! Fantastic! I ordered another set of O-Rings from them, so I don't have to mess with this again in the future.

Right on Time
These O-Rings are for my under-the-sink water purifier. The package comes with different sizes to fit many types of filters.

Not applicable!
I am disappointed in the set of "O" rings, though it shows the CBF3 "O" ring; this one doesn't have a groove. "O" ring for CBF3 is square with a groove. The round "O" ring failed to seal. Can you supply me with the right "O" ring? Thank you, George
