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. Review: 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. ## Features - Replacement 151122 o-rings compatible with Pentair/Pentek style Big Blue Water Filter Housings (3 Pack) - Includes 3 replacement o-rings (also called seals or gaskets) to repair your leaking water filter housing [OEM UPC: 051678511220 , 885343762095] - 151122 OEM Size o-rings are approximately 5.5" Inside Diameter x 5.83" Outside Diameter x 0.165" Thickness.

Essentially, no. A little bit, but O-rings are not elastic like rubber bands. **Q: Anyone tried these on us water systems magna (grey housing) filters?** A: It's plumbing. There's no way to know whether a gasket or part will fit without buying it and trying it. **Q: is this the o ring for an Aqua Flow 26258?** A: The filter housing for this ring is for a 20" Big Blue filter which was installed by Culligan......my guess is the diameter is a standard size for any 20" housing.....but best to confirm with Aqua Flow **Q: Will these fit the eco pure epw4 filter** A: i dont believe so ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Fit.
