Molded from a premium, high-density synthetic nitrile (Buna-N) rubber, this circular gasket features an internal diameter of 2.75 inches and a robust, custom quarter-inch cross-sectional thickness. Its primary structural role is to sit securely within the machined perimeter grooves of the internal plumbing elbow assemblies that connect the filter elements to the main bulkhead fittings. When the plumbing adapters are compressed, this custom O-ring establishes an absolute airtight and watertight seal capable of withstanding intense hydraulic operating pressures up to 50 PSI, preventing unfiltered water from bypassing the filter grid. Built to retain its elastic shape memory, resist compression set, and endure continuous exposure to fluctuating water temperatures and harsh pool chemicals like chlorine, bromine, and seasonal acid washes, this durable seal prevents pressure drop and internal weeping. Due to its thick-walled, custom elastomeric profile, this individual rubber O-ring carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"0\" data-index-in-node=\"1328\"\u003e0.04 pounds\u003c\/b\u003e (about 0.64 ounces).\u003cbr\u003e\u003c!----\u003e\n\u003c\/div\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53327096545391,"sku":"35505-7438Z","price":17.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/51OH0e3H7JL._AC_UF894_1000_QL80_b44e35e6-d8ae-4b6c-bace-5ea36e074291.jpg?v=1782229942","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-2-75-x-25-custom-elbow-o-ring","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
