{"product_id":"o-ring-6-1-2-id","title":"Pentair O-Ring, 6-1\/2\" ID for 2\" Multiport Valve","description":"\u003cp\u003eThis is the Pentair 275333 valve body o-ring, 6-1\/2\" on the inside diameter and 3\/16\" thick. It seals the multiport valve body on 2\" top mount and side mount valves, and it is one of the few parts in a filter valve that is guaranteed to need attention eventually.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA multiport valve holds pressure on the filter side of the system. The body o-ring is what keeps that pressure inside. When the ring hardens, flattens or takes a permanent set from years of compression, water finds the seam and the valve starts to seep, usually right after someone has opened it for the first time in a decade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMeasure the old ring before ordering: this one is 6-1\/2\" inside diameter, 3\/16\" thick. It also appears in the Pentair PacFab Tagelus sand filter parts listing, so Tagelus owners with a 2\" valve should check this size against theirs.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628854522068,"sku":"PAC-061-9577","price":13.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_73417a8c-da97-4731-bbea-5e370380ee2f.png?v=1788755404","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-6-1-2-id","provider":"Active Pool Supply","version":"1.0","type":"link"}
