Perfect Fit. Sat in Blue Blue Filter Housing and Secured First Attempt. 5 Stars
Don’t believe the AI overview or negative comments. These are the real deal. I just tried one of the three o Rings last night and it fits literally perfect. These guys should have made the OEM O rings because my original one was stretched out and this replacement one was perfect. I have the Big Blue Pentek OPAQUE 10 x 4.5 inch system. It sat perfectly in the borders of the cylinder and I was able to secure it with minimal lubricant grease my first attempt refastenig the cynlinder. Could not be happier with these O rings please don’t hesitate it’s totally worth the 15 dollars to not struggle with a heavy filter system.

Perfect fit
Perfect fit into my water filter tank. My older ones tended to get distorted if used too many times. That leads to leaks. The price of these is just right to buy a new one for every six month replacement. No leaks the first time I used it., and I did not have to reinstall it. I will be buying these repeatedly.
