["O-Ring Part Number: 27001-0061S (270010061S)","Compatible with Pentair / Sta-Rite System 2 PLM and PLD Series Filters: PLM100, PLM125, PLM150, PLM175, PLM200, PLM300, PLD50-DE, PLD70-DE, PLDE36, PLDE48 (Not compatible with filter tanks manufactured before February 1997).","O-Ring measures about 15-1/2” diameter across and about 3/8” Thickness. An exact match to the OEM o-ring seal that came with your filter when it was brand new. Molded from OEM spec synthetic rubber for long lasting performance and durability.","The 27001-0061S o-ring gasket is the large o-ring that seals between the top and bottom half of the compatible filter models listed above. This o-ring eventually wears out from being compressed in service for a long period of time. If you notice your filter dripping from the seam/band between the two halves, it’s time to replace your o-ring to restore your filter to peak performance.","Manufactured and warrantied by Captain O-Ring LLC. Proudly assembled in the USA!"]
