It measures 4.5 inches inside diameter, 4.688 inches outside diameter, and 0.094 inches thick, with a round cross section and a 70 Shore A durometer hardness rating. The fluoroelastomer compound delivers low compression set and high temperature resistance, making it a reliable choice for hydraulic, pneumatic, and fluid-handling assemblies operated at elevated temperatures or in chemically aggressive environments. Plumbers, HVAC technicians, and industrial maintenance techs are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring fits sealing grooves sized for a Dash 157 standard cross section and is suited for residential and commercial applications where petroleum-based fluids or high operating temperatures are present. Its low gas permeability makes it a good choice for vacuum service as well. The -15 degrees F to 400 degrees F service temperature range covers most HVAC refrigerant-side and fuel-handling service conditions. It is sold in a package of two.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound resists petroleum products, fuels, and a wide spectrum of chemicals\u003c\/li\u003e\n  \u003cli\u003eService temperature range of -15 degrees F to 400 degrees F for high-heat applications\u003c\/li\u003e\n  \u003cli\u003e70 Shore A durometer hardness provides firm, reliable compression seal\u003c\/li\u003e\n  \u003cli\u003eLow compression set extends service life in static and dynamic sealing grooves\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes it suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 157 standard sizing for straightforward groove fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with petroleum products and compatible fluids in systems requiring a Dash 157 standard O-ring groove.

Always depressurize and de-energize the system and drain any fluid before removing or replacing seals. Lubricate the O-ring with a compatible fluid or grease before installation to prevent tearing during assembly. Do not use petroleum-based lubricants incompatible with the mating system fluid, and inspect the groove for burrs or damage before seating the new ring.\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: 157\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches (3\/32 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 and compatible 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: 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: ZMSCV70157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713852309810,"sku":"ZMSCV70157","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1232f0c8cecdf2d4a7b46d851465eba.jpg?v=1788495372","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70157-viton-o-ring-dash-157","provider":"Voomi Supply","version":"1.0","type":"link"}
