Molded from premium, chemical-resistant synthetic rubber elastomers (such as Buna-N or EPDM nitrile rubber), this specialized circular gasket sits tightly within a machined groove just under the valve’s clear inspection cover or screw cap. Its primary purpose is to establish an airtight, watertight compression seal that maintains system priming, prevents high-pressure water leaks from spraying out of the top of the plumbing, and keeps external air from being drawn into the filtration line when the pool pump drops into a vacuum cycle.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\" id=\"p-rc_fd4c719295efa268-187\"\u003e\u003cspan class=\"citation-1566 citation-end-1566\"\u003eBecause it is a small, flexible rubber ring, its weight is virtually negligible:\u003csup class=\"superscript\" data-turn-source-index=\"1\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"2\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,0,0\"\u003e\u003cb data-path-to-node=\"2,0,0\" data-index-in-node=\"0\"\u003eActual Product Weight:\u003c\/b\u003e Approximately \u003cb data-path-to-node=\"2,0,0\" data-index-in-node=\"37\"\u003e0.01 to 0.02 pounds\u003c\/b\u003e (roughly 0.16 to 0.32 ounces).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,1,0\" id=\"p-rc_fd4c719295efa268-188\"\u003e\u003cb data-path-to-node=\"2,1,0\" data-index-in-node=\"0\"\u003ePackaged Shipping Weight:\u003c\/b\u003e\u003cspan class=\"citation-1565\"\u003e Usually listed around \u003c\/span\u003e\u003cb data-path-to-node=\"2,1,0\" data-index-in-node=\"48\"\u003e\u003cspan class=\"citation-1565\"\u003e0.05 pounds\u003c\/span\u003e\u003c\/b\u003e\u003cspan class=\"citation-1565 citation-end-1565\"\u003e (less than an ounce) when shipped in a standard mailer or protective plastic envelope.\u003csup class=\"superscript\" data-turn-source-index=\"2\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"4\"\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.youtube.com\/watch?v=Svi8nsQPf4w\" class=\"ng-star-inserted\" data-hveid=\"0\" data-ved=\"0CAAQ_4QMahgKEwjjyKyP7MCVAxUAAAAAHQAAAAAQ7Ag\" target=\"_blank\"\u003ePentair Filter Tank Bottom Replacement Tutorial\u003c\/a\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e provides a step-by-step visual demonstration on how to safely replace a damaged or leaking lower tank assembly on a Pentair cartridge filter system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\n\u003c\/div\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53722438402159,"sku":"R172451","price":2.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/s-l500__49763.jpg?v=1783439970","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-check-valve-o-ring","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
