It measures 3.75 inches inside diameter, 4 inches outside diameter, and 0.125 inches thick with a round cross-section profile. Rated hard at a Shore A hardness of 70, this O-ring maintains a low compression set and resists gas permeation, making it well-suited for demanding industrial and mechanical sealing work. Each package contains 5 rings. Licensed HVAC technicians, plumbers, and industrial mechanics regularly specify fluoroelastomer O-rings for high-heat and fluid-contact service points.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for sealing applications that involve petroleum products, hydraulic fluids, and a wide range of chemicals. Its operating temperature range spans from -15 degrees F to 400 degrees F, covering most high-temperature service conditions found in HVAC refrigerant circuits, plumbing connections, pump assemblies, and industrial fluid systems. The Dash 240 sizing designation is a standard AN\/AS568 callout, allowing direct cross-reference with OEM seal specifications. Vacuum service and low-gas-permeability applications are also within its rated capabilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton-type) material for broad chemical and petroleum compatibility\u003c\/li\u003e\n  \u003cli\u003eTemperature range: -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 with hard hardness rating and low compression set\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile per Dash 240 (AN\/AS568) standard sizing\u003c\/li\u003e\n  \u003cli\u003eSuitable for vacuum service and low gas permeability applications\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 rings per order\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 systems requiring a Dash 240 round-cross-section fluoroelastomer O-ring; rated compatible with petroleum products and a wide spectrum of industrial chemicals.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation should be performed by a qualified mechanic, plumber, or HVAC technician. Depressurize and drain the system completely before removing the old seal, and inspect the groove and mating surface for scoring or contamination. Apply a compatible O-ring lubricant sparingly before seating the ring to prevent rolling or nicking during assembly. Do not stretch the O-ring beyond the minimum required to seat it in the groove.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton-type)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 240\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4 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: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum products, wide-spectrum chemicals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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  \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: ZMSCV70240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689416720690,"sku":"ZMSCV70240","price":17.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48c498482f0f83ce3f73dfef7b6f5f5f.jpg?v=1788259143","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70240-viton-o-ring-dash-240-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
