Molded from a premium, heavy-duty synthetic rubber compound, this O-ring is specifically formulated to withstand continuous compression, extreme water temperatures, and prolonged exposure to harsh pool chemicals like chlorine and acid. Its primary structural role is to create an absolute watertight seal between the filter's internal plumbing elbow and the small bulkhead assembly, effectively preventing high-pressure external leaks and maintaining the system's hydraulic efficiency. Despite its robust elasticity and durable cross-sectional thickness, this small mechanical hardware component is exceptionally light, carrying a total product and shipping weight of approximately \u003cb\u003e0.02 pounds\u003c\/b\u003e (less than half an ounce), making it a simple yet critical replacement part for routine filter maintenance.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53322469441647,"sku":"35505-1429Z","price":8.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/1733539_1e22f881-3c36-4be5-b2c3-4b94bcd18734.webp?v=1782139554","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-drain-cap-sand-filter-1","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
