Measuring 3.375 inches inside diameter, 3.75 inches outside diameter, and 0.1875 inches thick, this round cross-section ring carries a Shore A hardness of 70. Viton compound delivers low compression set and low gas permeability, making it a dependable choice for demanding fluid and vacuum sealing environments. Each order includes a pack of 5 rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for HVAC, refrigeration, plumbing, and industrial fluid systems where petroleum-based media, high operating temperatures, or vacuum service conditions are present. Typical installations include pump seals, valve seats, flange joints, and fitting connections that see elevated temperatures or exposure to oils, fuels, and hydraulic fluids. The fluoroelastomer compound provides a wide spectrum of chemical compatibility, making this ring appropriate for both residential and commercial service applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) material rated for service from -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 70 Shore A hardness for reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eLow compression set maintains seal integrity over repeated thermal cycles\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability suited for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 5 for common replacement and stocking needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement Dash 340 O-ring for applications requiring a 3.375-inch ID fluoroelastomer seal compatible with petroleum products and high-temperature service conditions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance technicians. Shut off and depressurize the system before removing the old O-ring and seating the replacement. Inspect the groove for damage or debris before installation and apply a compatible lubricant to the ring to ease seating and prevent twisting. Do not overstretch the ring during installation, as distortion reduces sealing effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 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: -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\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: ZMSCV70340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699871416626,"sku":"ZMSCV70340","price":24.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70bb60828a8e60d5cbd89d248d969317.jpg?v=1788382321","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70340-viton-o-ring-dash-340-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
