The clamp is the band that pulls them together and holds that seal against system pressure. It is a structural part, so a clamp that has cracked, stretched or corroded through is not something to keep tightening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChasing a seam leak\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhen water weeps from the seam, most people replace the tank o-ring, which is right most of the time. If the leak comes straight back, look at the clamp itself. A band that has lost its shape, a bolt that has rusted and will no longer draw evenly, or a lug that has started to split will all leave one section of the seam under less pressure than the rest, and the o-ring cannot make that up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAlways release system pressure and open the air relief before touching the clamp on a running filter. Draw the new clamp down evenly, and check that the tank halves are seated squarely before applying full torque.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48634156417236,"sku":"STA-051-3765","price":81.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_0a7f1268-501b-453f-b2b0-915d81b97637.jpg?v=1788825973","url":"https:\/\/www.activepoolsupply.com\/products\/top-clamp","provider":"Active Pool Supply","version":"1.0","type":"link"}
