It measures 2.875 inches inside diameter and 3.0 inches outside diameter, with a wall thickness of 0.0625 inches. The 70-durometer hardness rating places it in the hard range, providing solid compression resistance under load. Rated for continuous service from -80 degrees F to 450 degrees F, this O-ring is suited for sealing applications that demand wide thermal range capability and good dry heat resistance. HVAC technicians, plumbers, and industrial service professionals install this type of seal in fluid and gas handling assemblies where elevated or sub-ambient temperatures are routine.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is commonly used in applications involving oils, chemicals, and solvents where a flexible yet durable seal is required. Its silicone compound delivers good weather and ozone resistance, making it a practical choice for outdoor or exposed mechanical assemblies. It is suitable for use in HVAC equipment, plumbing fittings, pump housings, and general fluid-system sealing tasks. The white color aids in visual inspection during installation. Note that oil resistance is limited with this compound; verify fluid compatibility before installation in heavy-oil environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 040 standard sizing: 2.875 inches ID, 3.0 inches OD, 0.0625 inches thick\u003c\/li\u003e\n  \u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F operating range\u003c\/li\u003e\n  \u003cli\u003e70-durometer hardness for firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed service environments\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in moderate-exposure applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service seal for fluid and gas handling assemblies requiring a Dash 040 silicone O-ring with a round cross section and 70-durometer hardness rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always depressurize and isolate the system before removing or installing seals. Inspect the O-ring groove for burrs, scoring, or debris before seating the new ring. Avoid using petroleum-based lubricants during installation, as they may degrade silicone compounds; use a silicone-compatible assembly lubricant instead.\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\u003eInside Diameter\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 040\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 durometer (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 Media\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  \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: ZMSCS70040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67915239555378,"sku":"ZMSCS70040","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f304bd67e6999157072f2ffc991acde.jpg?v=1791252808","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70040-silicone-o-ring-dash-040","provider":"Voomi Supply","version":"1.0","type":"link"}
