{"product_id":"h-series-valve-body-o-ring","title":"Pentair H-Series Valve Body O-Ring","description":"\u003cp\u003eThe Pentair 71427 is the H-Series valve body o-ring. It is the genuine factory seal for the valve body, and it turns up on several older valve families.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it is used\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair lists it for the American Products 2 in. H and M Series multiport valves, and for the Purex 2000 Series backwash valves fitted to SM and SMBW filters. It also appears in the QuietFlo and Aquatron pump parts listings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it fails\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eO-rings do not wear out so much as they harden. Years of heat, chlorine and compression take the spring out of the rubber, it takes a permanent set, and the seal starts weeping at the body. The leak looks like a failed valve, which is how a five dollar part ends up costing someone a whole multiport.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you are in there\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe union o-ring and the rotor shaft o-ring are separate parts. If the valve is coming apart anyway, it is worth having all three on hand rather than opening it twice.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627968147668,"sku":"PUR-061-3402","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_2f472804-174c-454f-aa78-b3d370486660.png?v=1788731926","url":"https:\/\/www.activepoolsupply.com\/products\/h-series-valve-body-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
