With a 4.75-inch inside diameter, 4.875-inch outside diameter, and 0.0625-inch thickness, this Dash 048 O-ring seats into standard AN\/AS568 dash-048 grooves. The fluoroelastomer compound delivers a 70-durometer hardness rating, providing a hard, resilient seal with low compression set. Its temperature range of -15 degrees F to 400 degrees F makes it suitable for high-heat service environments where standard nitrile compounds fall short.\u003c\/p\u003e\u003cp\u003eThis O-ring is commonly installed in petroleum fluid lines, hydraulic circuits, refrigeration service ports, pump housings, and valve bodies. Its wide chemical compatibility and low gas permeability make it a reliable choice in vacuum service applications. HVAC technicians, plumbers, and industrial maintenance professionals regularly use this size in large-bore fittings and flanged connections. The round cross-section profile provides uniform contact stress around the full seating surface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound with broad chemical resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003e70-durometer hardness rating with low compression set for long-term sealing integrity\u003c\/li\u003e\n\u003cli\u003eOperating temperature range from -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eSuitable for vacuum service with low gas permeability\u003c\/li\u003e\n\u003cli\u003eRound cross-section, Dash 048 profile fits standard AN\/AS568 groove specifications\u003c\/li\u003e\n\u003cli\u003eBlack color; sold in a package quantity of 2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 048 fluoroelastomer O-ring compatible with petroleum products, hydraulic fluids, and applications requiring high-temperature resistance.

Always depressurize and isolate the system before replacing any O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during assembly. Avoid twisting or rolling the O-ring into the groove, and inspect the groove surface for damage or contamination before installation.\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: 048\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 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 Durometer (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\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: ZMSCV70048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698519212338,"sku":"ZMSCV70048","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/870f9d4e1e537fc0e262f83315d56791.jpg?v=1788364124","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70048-viton-o-ring-dash-048","provider":"Voomi Supply","version":"1.0","type":"link"}
