{"product_id":"filter-tank-o-ring","title":"Jacuzzi OEM Filter Tank O-Ring for Sherlock Filter","description":"\u003cp\u003eJacuzzi 47038047R is the OEM tank o-ring for Sherlock filters. It seals the joint between the two halves of the filter tank, which is the one place on a filter that has to hold pressure every minute the pump runs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSizing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe ring measures 11-3\/4\" across the outside, 11-3\/8\" across the inside, and 3\/16\" thick, in rubber. Those three numbers matter more than they look: an o-ring a fraction too thin will not fill the groove under clamp load, and one a fraction too large rolls out of the groove as the tank closes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater weeping from the tank seam is the classic symptom. Rubber that has gone hard, taken a flat set in the groove, or picked up a nick from a screwdriver will not seal again however tight the clamp is drawn, and overtightening to chase the leak only damages the clamp. Fit a fresh ring instead, and make a habit of replacing it whenever the tank is opened for a filter service.\u003c\/p\u003e","brand":"Jacuzzi Bros.","offers":[{"title":"Default Title","offer_id":48627954450644,"sku":"JAC-051-6420","price":32.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d2c21bc8-e80a-4bc8-a77f-899bbd3e7793.png?v=1788730903","url":"https:\/\/www.activepoolsupply.com\/products\/filter-tank-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
