It is the seal between the tail piece and its mating union half.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnions let a pump, filter or valve be broken loose without cutting pipe, and the o-ring is what makes that joint watertight. It is listed among Waterway Crystal Water cartridge filter parts and the push pull DE valve parts, and it is the 2.5 inch size specifically.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing a leak\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA union that drips while the pump runs, or that draws air on the suction side, is almost always down to this seal. Rubber flattens, dries and picks up nicks from grit, and once it takes a set it will not seal again no matter how hard the collar is tightened. Overtightening a union to chase a leak usually cracks the collar, so change the o-ring instead. A light film of silicone lubricant rated for pool use helps it seat and makes the next disassembly easier.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48633784172756,"sku":"WWP-251-0232","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_b0f36dec-a38a-42fe-bafa-c7370c5d609f.png?v=1788816321","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-2-5-tail-piece","provider":"Active Pool Supply","version":"1.0","type":"link"}
