{"product_id":"cover-o-ring-4","title":"SuperPro Cover O-Ring","description":"\u003cp\u003eSuperPro O-47-9 is a cover O-Ring measuring 9\/16 inch inside diameter with a 3\/32 inch cross section. It appears in two places worth knowing about: the 2 inch Pentair push-pull valve parts, and the Purex 4000 Series molded DE filter parts covering SM and SMBW models 4024, 4036 and 4048.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKnow the other numbers\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe same ring is cross referenced as 272406, as O-47, and as 90-423-5113. That matters when you are working from an old diagram or a distributor list, because the number printed there may not be the one on the box. All of them point at this seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCover seals fail quietly. They do not blow out, they harden, take a permanent set where the cover has been clamped on them, and start letting water past under pressure. The test is simple: flex the old ring between your fingers. If it is stiff, cracked or has a flat pressed into one side, it is finished. Clean the groove, fit the new one with a light film of silicone based O-Ring lubricant, and it will seat evenly and come apart cleanly next time.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48635042857172,"sku":"SPG-601-1210","price":2.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_817e72c3-00cf-4ec7-a571-76d3f3d1003b.jpg?v=1788840519","url":"https:\/\/www.activepoolsupply.com\/products\/cover-o-ring-4","provider":"Active Pool Supply","version":"1.0","type":"link"}
