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- fixed leaking Big Blue #20
Fast shipping. Perfect fit at a great price. The airing fit perfectly and fixed the leak in my Big Blue. I also ordered a new filter. Highly recommend this product. I got three for what Home Depot would charge for one. Highly recommend seller.
