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. Review: Perfect fit replacement parts - Perfect fit on water filter housing. Best practices are to replace o-ring on filter housing with each filter change. I put a light coat of 100% silicone on the o-ring before putting in housing channel to prevent any binding when tightening. ## 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.
