{"product_id":"o-ring-5-16-i-d","title":"Pentair O-Ring, 5\/16 Inch I.D.","description":"\u003cp\u003eThis is a Pentair replacement o-ring measuring 5\/16 inch inside diameter with a 3\/32 inch cross section. It is a common small size used across a number of applications rather than dedicated to one assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatching by number\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe listing carries more than one identifier. O-628-9 is the manufacturer part number, 33455-1047 is given as the OEM number, and it is cross referenced to O-628, 5057-28 and 90-423-5109. Any of those numbers on an old parts list points at this same ring, which is worth knowing when working from an older diagram.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMatch the ring by measuring, not by appearance. Inside diameter and cross section together decide whether it seats. When you fit it, use a silicone based pool lubricant and never a petroleum grease, and replace the old ring rather than reusing it, since compressed rubber takes a set and leaks again within a season.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48634279002324,"sku":"SPG-601-1224","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_80319332-9adf-49d6-ade5-2dcfba5c1e64.jpg?v=1788828036","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-5-16-i-d","provider":"Active Pool Supply","version":"1.0","type":"link"}
