It measures 3.75 inches inside diameter and 3.938 inches outside diameter, with a thickness of 0.094 inches. The 70-durometer silicone compound delivers a working temperature range of -80 degrees F to 450 degrees F, making it well suited for sealing applications that demand wide thermal tolerance and dry heat resistance. HVAC technicians, plumbers, and mechanical service professionals use this O-ring where a reliable, heat-stable seal is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for use in HVAC systems, plumbing assemblies, pool and spa equipment, and general mechanical applications where exposure to wide temperature swings, weathering, or ozone is a concern. The silicone material offers good weather and ozone resistance and limited oil resistance. It is suitable for contact with certain oils, chemicals, and solvents in appropriate concentrations. Each package contains 10 O-rings, and the minimum order quantity is 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone compound with a working range of -80 degrees F to 450 degrees F for wide thermal tolerance\u003c\/li\u003e\n  \u003cli\u003e70-durometer hardness rating for firm sealing in standard groove applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section ensures consistent contact and reliable sealing force\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 appropriate service conditions\u003c\/li\u003e\n  \u003cli\u003ePack of 10 units with a minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 154 O-ring replacement for use in grooves and ports sized for a 3.75-inch inside diameter round-cross-section seal across HVAC, plumbing, pool, and general mechanical equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, plumber, or qualified mechanical technician. Always de-energize or shut off the system and relieve all pressure before replacing an O-ring. Inspect the groove and mating surfaces for nicks or contamination before seating the new O-ring, and apply a compatible lubricant to ease installation without damaging the sealing surface. Confirm that silicone is appropriate for the specific fluid and pressure conditions in the application before installation.\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\u003eDash Number\u003c\/strong\u003e: 154\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.9380 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 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 (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 Materials\u003c\/strong\u003e: Oils, Chemicals, Solvents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\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: 10\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: ZMSCS70154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723133419826,"sku":"ZMSCS70154","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_7cb1ba97-91bd-45fe-a0f0-6748fdb73725.jpg?v=1788601062","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70154-silicone-o-ring-dash-154","provider":"Voomi Supply","version":"1.0","type":"link"}
