This ring measures 3.625 inches inside diameter, 3.875 inches outside diameter, and 0.125 inches thick. With a Shore A hardness of 70, it holds its shape under compression while remaining pliable enough for consistent sealing. Silicone construction gives this O-ring good dry heat resistance, weather resistance, and ozone resistance, making it a dependable choice for HVAC, plumbing, pool, and light industrial service work. Each package contains 5 rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial sealing applications where exposure to wide temperature swings, outdoor weathering, or ozone is a concern. Common install scenarios include pump housings, valve stems, filter housings, and equipment access covers in HVAC and pool systems. It is compatible with oils, chemicals, and solvents at moderate concentrations. Limited oil resistance should be factored into any high-oil-exposure application. Trade installers typically select this ring as a field replacement or service-kit component when working on equipment with Dash 239 groove specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone material rated from -80 degrees F to 450 degrees F for wide temperature service\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 (hard rating) for reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross section at 0.125 inches thick for standard Dash 239 groove fitment\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in low-to-moderate concentrations\u003c\/li\u003e\n  \u003cli\u003ePackaged in a quantity of 5 rings per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 239 O-ring replacement for any groove dimensioned to accept a 3.625 inches ID by 3.875 inches OD by 0.125 inches cross-section seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring replacement is typically performed by licensed plumbers, HVAC technicians, or pool service professionals. Always de-energize equipment and relieve system pressure before disassembling any fitting or housing. Inspect the groove for nicks or corrosion before seating the new ring, and avoid stretching the ring beyond its natural diameter during installation. Lubricants compatible with silicone compounds may be used to aid installation where the application allows.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 239\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70 (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -80 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible With\u003c\/strong\u003e: Oils, Chemicals, Solvents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCS70239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709904290098,"sku":"ZMSCS70239","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfe6c7a6e9c955a67ba03545e195c64e.jpg?v=1788462072","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70239-silicone-o-ring-dash-239-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
