{"product_id":"18-diameter-tank-o-ring","title":"Pentair Genuine OEM 18\" Diameter Tank O-Ring","description":"\u003cp\u003ePentair 152127 is the tank o-ring for filter tanks with an 18 inch diameter body. It is the genuine Pentair part, molded in rubber.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tank o-ring sits in the joint between the two halves of the filter body. Every bit of pressure the pump makes is trying to push that joint open, and the ring is the only thing holding water in. When it hardens, flattens or nicks, the filter starts weeping at the band and the tank will not hold pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMeasure the tank body and compare the ring you pulled out. Pentair uses several tank ring sizes across its filter lines, so the 18 inch measurement is the thing to confirm rather than the model name on the label. Wipe the groove clean and use a silicone based o-ring lubricant when you fit the new ring.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627701448916,"sku":"PAC-051-2801","price":59.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_75cbd535-156b-4235-8002-d12c279b0024.png?v=1788726760","url":"https:\/\/www.activepoolsupply.com\/products\/18-diameter-tank-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
