It measures 5.25 inches inside diameter, 5.375 inches outside diameter, and 0.0625 inches thick, conforming to the Dash 050 designation. With a durometer hardness of 70 Shore A, this ring holds its shape under compression while maintaining a reliable seal. Silicone compound provides strong resistance to dry heat and weathering, making it a practical choice wherever standard elastomers fall short. Licensed plumbers, HVAC technicians, and mechanical service professionals commonly specify this size for large-bore fittings, flanges, and equipment access panels.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications that demand a wide service temperature range. Its silicone material performs from -80 degrees F up to 450 degrees F, making it appropriate for high-heat HVAC equipment, pool heater plumbing, and general mechanical assemblies exposed to outdoor weather and ozone. It is sold in a package quantity of 10, making it convenient for service fleets and shop stock. Note that silicone offers limited oil resistance; verify fluid compatibility before installation in oil-wetted systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWide temperature range: -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 050 standard sizing\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor and exposed installations\u003c\/li\u003e\n  \u003cli\u003eWhite silicone compound with good dry heat resistance\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10 for efficient shop and fleet stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 050 silicone O-ring replacement for large-bore fittings, flanges, and equipment housings that require a 5.25-inch inside diameter seal in plumbing, HVAC, pool, and general mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down or shut off the system and relieve all pressure before replacing any O-ring. Clean the sealing groove thoroughly and inspect for nicks or corrosion that could compromise the seal. Silicone O-rings are generally installed dry or with a silicone-compatible lubricant; avoid petroleum-based greases, which can degrade silicone compounds. Verify that the replacement ring is compatible with the process fluid before returning the system to service.\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: 050\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCS70050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706751320370,"sku":"ZMSCS70050","price":17.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_6b38a824-66bc-4d83-b352-df447da05633.jpg?v=1788436444","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70050-silicone-o-ring-dash-050","provider":"Voomi Supply","version":"1.0","type":"link"}
