It measures 5 inches inside diameter, 5.188 inches outside diameter, and 0.094 inches thick. Rated at 70 durometer hardness, this O-ring handles operating temperatures from -15 degrees F to 400 degrees F. Viton compound provides low compression set, good vacuum service capability, low gas permeability, and broad chemical compatibility. Licensed technicians and journeymen across HVAC, plumbing, hydraulics, and industrial trades use this O-ring for static and dynamic sealing applications where petroleum-based fluids or elevated temperatures are present.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in fuel systems, oil circuits, hydraulic assemblies, refrigerant service fittings, and high-temperature plumbing connections. Its fluoroelastomer compound makes it appropriate for environments where standard nitrile or EPDM rings would degrade prematurely due to chemical exposure or heat. Typical installations include pump seals, valve bonnets, flange faces, and threaded fitting seats in residential and commercial mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eViton (fluoroelastomer) compound resists petroleum products, fuels, and a wide spectrum of chemicals\u003c\/li\u003e\n  \u003cli\u003eOperating range of -15 degrees F to 400 degrees F suits high-temperature service environments\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness rating classified as hard — reduces extrusion under pressure\u003c\/li\u003e\n  \u003cli\u003eLow compression set maintains sealing force over long service intervals\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability and good vacuum service performance\u003c\/li\u003e\n  \u003cli\u003eRound cross section in standard Dash 159 sizing for drop-in replacement use\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece package (minimum order quantity of 1 package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 159 O-ring replacement for any groove or port machined to Dash 159 dimensions in HVAC, plumbing, hydraulic, or industrial equipment.

Relieve all pressure and drain fluid from the circuit before removing the existing O-ring. Clean the groove thoroughly and inspect for burrs or damage before seating the new ring. Apply a thin film of compatible fluid or O-ring lubricant to ease installation and prevent nicking during assembly — avoid petroleum-based greases if the media is incompatible.\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: 159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.188 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 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\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 pieces\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: ZMSCV70159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717118099762,"sku":"ZMSCV70159","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8acf08be540c8c0fd77c17e684e7d911.jpg?v=1788535963","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70159-viton-o-ring-dash-159-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
