{"product_id":"heavy-duty-clamp","title":"Hayward Heavy Duty Clamp","description":"\u003cp\u003eThe Hayward SX310N is the heavy duty ring flange clamp that joins the dome to the tank on Hayward sand filters. It is the genuine Hayward part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment and size\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt is listed for the S310S, S311SX, S311SXV and S360SX filters. The clamp measures 8 inches outside diameter with the ends touching, 3\/4 inch from top to bottom, and 5\/16 inch thick from inside to outside. If you are matching an unlabeled clamp, measure it with the ends brought together before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTreat it as a safety part\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhenever the pump is running, this clamp is holding a pressurised vessel closed. Rust scale, cracks around the bolt lug, or a band that has been sprung out of round all reduce how much it can hold. None of that is worth repairing. While the dome is off, check the o-ring under it too, because the clamp can only do its job if the gasket it presses on is still sound.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48628890206420,"sku":"HAY-051-8258","price":80.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_fcc9a97d-7049-4055-9b45-1e12223fa2ee.png?v=1788756996","url":"https:\/\/www.activepoolsupply.com\/products\/heavy-duty-clamp","provider":"Active Pool Supply","version":"1.0","type":"link"}
