With a 3.625-inch inside diameter, a 4-inch outside diameter, and a 0.1875-inch round cross section, this O-ring seats into standard Dash 342 grooves without modification. A Shore hardness rating of 70 provides firm sealing force with low compression set, maintaining a reliable seal over extended service cycles. HVAC technicians, plumbers, and industrial maintenance professionals install this part wherever fluoroelastomer compatibility is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum products, hydraulic fluids, oils, and high-temperature process fluids. Its operating temperature range of -15 degrees F to 400 degrees F makes it appropriate for equipment exposed to wide thermal swings, including HVAC refrigerant circuits, fuel-handling assemblies, and vacuum service applications. The low gas permeability characteristic supports vacuum service where elastomer outgassing must be minimized. Each package contains 2 O-rings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) construction provides strong resistance to petroleum products and a wide spectrum of chemical exposure\u003c\/li\u003e\n  \u003cli\u003eOperating range of -15 degrees F to 400 degrees F suits high-temperature and thermal-cycling environments\u003c\/li\u003e\n  \u003cli\u003eShore 70 hardness rating delivers firm sealing with low compression set for long service life\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard Dash 342 groove dimensions\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes this O-ring suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eBlack color; sold in a 2-pack per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service O-ring for any application requiring a standard Dash 342 fluoroelastomer seal; compatible with petroleum products and equipment where Viton or fluoroelastomer material is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Always de-energize, depressurize, and isolate the fluid circuit before removing the existing O-ring. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant prior to seating to prevent pinching or tearing during installation. Do not stretch the O-ring beyond what is necessary to seat it in the groove, and inspect the groove surface for nicks or corrosion before reinstalling any fitting or component.\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: 342\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.625 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: 0.1875 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 (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: 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\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: ZMSCV70342\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694614020402,"sku":"ZMSCV70342","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abcdad91e1cae40bf99eafded0f11f6a.jpg?v=1788326297","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70342-viton-o-ring-dash-342-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
