With a 4.25-inch inside diameter, 4.625-inch outside diameter, and a 0.1875-inch round cross section, this O-ring delivers a reliable seal across a wide temperature range of -15 degrees F to 400 degrees F. The fluoroelastomer compound provides low compression set and low gas permeability, making it well suited for vacuum service and high-temperature fluid containment. Licensed trades and maintenance professionals install this ring as an OEM-style replacement or new installation component wherever a Dash 347 dimension is specified.\u003c\/p\u003e\u003cp\u003eThis O-ring is used across residential and commercial HVAC, plumbing, pool, and industrial fluid-handling systems where petroleum-based fluids, hydraulic oils, or high-temperature gases are present. Its wide chemical compatibility makes it a common choice for pump housings, valve bodies, manifold connections, and refrigerant-side components requiring a hard 70-durometer seal. The round cross-section profile seats consistently in standard Dash 347 grooves, reducing installation errors during field service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound rated for continuous service from -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness (Hard rating) for reliable compression and low blowout risk\u003c\/li\u003e\n\u003cli\u003eLow compression set maintains sealing force over extended service intervals\u003c\/li\u003e\n\u003cli\u003eLow gas permeability suits vacuum service and pressurized fluid containment\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products and a wide spectrum of chemical compatibility\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile fits standard Dash 347 groove dimensions without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 347 O-ring replacement compatible with petroleum products and systems requiring fluoroelastomer sealing material.

Depressurize and de-energize the system fully before removing any existing seals or opening fluid circuits. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Inspect the groove for burrs or corrosion before installing the new ring to ensure a proper, leak-free seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 347\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.625 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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\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: 2\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZMSCV70347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689089073458,"sku":"ZMSCV70347","price":15.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/430c5d55bcfa4d1355e8c06f03c654d1.jpg?v=1788254611","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70347-viton-o-ring-dash-347","provider":"Voomi Supply","version":"1.0","type":"link"}
