It measures 2.188 inches inside diameter, 2.375 inches outside diameter, and 0.094 inches thick, with a round cross section. The 70 durometer hardness rating classifies it as a hard compound, which helps maintain low compression set under sustained load. Operating temperature range spans -15 degrees F to 400 degrees F, making it suitable for high-heat environments where standard nitrile or EPDM seals would fail.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is intended for use in applications that involve petroleum-based fluids, hydraulic oils, fuels, and a wide spectrum of chemicals. Its fluoroelastomer compound provides good resistance to petroleum products, low gas permeability, and suitability for vacuum service. Typical installation scenarios include pump housings, valve bodies, fittings, and fluid system components found in industrial, HVAC, plumbing, and mechanical maintenance settings. It is sold in packages of 10 units, with a minimum order quantity of 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) material for high-temperature and chemical resistance up to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness for low compression set under sustained clamping load\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 139 standard sizing for consistent fit in grooved hardware\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products, hydraulic fluids, and a wide range of chemicals\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes it suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eBlack color; sold in 10-piece packages\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 139 O-ring replacement for use in grooves and fittings that accept a 2.188-inch ID, 2.375-inch OD, 0.094-inch cross-section seal.

Depressurize and isolate the system completely before removing the old seal. Inspect the groove and mating surfaces for damage or debris before seating the new O-ring. Avoid rolling or twisting the O-ring during installation, and apply a compatible lubricant to ease seating without compromising the seal.\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\u003eInside Diameter\u003c\/strong\u003e: 2.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 139\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\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\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: ZMSCV70139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715862790450,"sku":"ZMSCV70139","price":15.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3c2b3176b5610c39333de1a4f00eb3f.jpg?v=1788519157","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70139-viton-o-ring-dash-139","provider":"Voomi Supply","version":"1.0","type":"link"}
