It measures 2.5 inches inside diameter, 2.688 inches outside diameter, and 0.0937 inches thick. The silicone compound provides a wide service temperature range from -80 degrees F to 450 degrees F, making it well suited for applications that demand reliable sealing under both extreme cold and dry heat conditions. It carries a hardness rating of 70 Shore A, classified as hard. Licensed plumbers, HVAC technicians, and industrial maintenance trades use these O-rings when replacing worn or damaged seals in fluid and gas system connections.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for use in residential and light commercial plumbing, HVAC equipment, and general industrial assemblies where exposure to a wide temperature range is expected. Silicone material offers good resistance to weathering and ozone, making it a practical choice for outdoor or UV-exposed installations. It has limited oil resistance, so it is best deployed in systems handling water, air, mild chemicals, or solvents rather than petroleum-based fluids. Each package contains 10 O-rings, which supports both single-repair and routine stock replenishment needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 144 standard sizing: 2.5 inches ID, 2.688 inches OD, 0.0937 inches thick\u003c\/li\u003e\n  \u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for firm sealing in high-temperature dry environments\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor and exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, mild chemicals, and solvents; limited petroleum oil resistance\u003c\/li\u003e\n  \u003cli\u003eRound cross section for standard groove fitment across common seal housings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement O-ring for any application requiring a Dash 144 round cross-section silicone seal in plumbing, HVAC, or industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut down and depressurize the system before removing the existing O-ring. Clean the groove and mating surfaces of debris or old sealant before seating the new ring. Do not stretch the O-ring beyond what is needed for installation, as overstretching can reduce effective cross-section and compromise the seal. Consult applicable plumbing or mechanical codes such as IPC or ASME standards for pressure system service requirements in your jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 144\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\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\u003eHardness\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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\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: ZMSCS70144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715582034226,"sku":"ZMSCS70144","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_54351782-cdde-4ae6-9544-929bc6ae3694.jpg?v=1788515929","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70144-silicone-o-ring-dash-144","provider":"Voomi Supply","version":"1.0","type":"link"}
