It is the seal between the two halves of the filter body, held closed by the band clamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen it needs changing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe usual sign is water at the seam. A tank o-ring lives under constant compression and constant pressure cycling, and over a few seasons it takes a set, loses its spring and stops filling the groove. Once that happens the clamp can be torqued correctly and the tank will still weep. A nick from a stone or a ring pinched during a clumsy reassembly does the same thing much faster.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWipe the groove and the sealing face clean before the new ring goes in, since grit left behind will hold the joint open. Use a silicone lubricant, not a petroleum grease, and bring the clamp down evenly rather than tightening one side at a time.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48634985742548,"sku":"ALA-601-4604","price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/ALA-601-4604_1a.png?v=1788839298","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-hayward-c-250-f-tank","provider":"Active Pool Supply","version":"1.0","type":"link"}
