Fabricated from a high-grade, chemical-resistant synthetic rubber compound, this large O-ring sits directly within the machined channel of the plumbing adapter flange to form an absolute watertight and airtight compression seal under extreme commercial flow rates. Its primary structural role is to prevent high-pressure external leaks at the critical junction where the heavy-duty multiport control valve or piping manifold mates to the fiberglass filter tank body. Built to retain its elasticity and resist degradation despite constant exposure to concentrated pool sanitizers, fluctuating water temperatures, and continuous hydraulic stress, this robust sealing ring is essential for maintaining proper system pressure. Because it is a streamlined rubber component with a specialized cross-sectional thickness, this individual O-ring carries a net product and shipping weight of approximately \u003cb\u003e0.06 pounds\u003c\/b\u003e (about 0.96 ounces), making it a crucial yet lightweight part for routine commercial filter maintenance.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53322493624431,"sku":"154004Z","price":13.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/1733539_1f63dfba-8023-43e0-9517-68ed3e1c2077.webp?v=1782140058","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-2-342-flange-adapter-o-ring-for-triton%c2%ae-c-3-sand-filter","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
