With a 0.739-inch inside diameter, 0.875-inch outside diameter, and a 0.0625-inch thick round cross section, this O-ring meets standard Dash 018 dimensional specifications. Rated for service from -40 degrees F to 250 degrees F, it is compatible with petroleum-based fluids and offers reliable compression set resistance, tear resistance, and abrasion resistance. Each package contains 25 O-rings. Installation is performed by licensed plumbers, HVAC technicians, or mechanical service professionals.\u003c\/p\u003e\u003cp\u003eBuna-N O-rings in the Dash 018 size are commonly used in residential and commercial applications wherever a 3\/4-inch ID seal is required. Typical uses include refrigerant service fittings, hydraulic line connections, pump seals, valve bodies, and fluid-handling assemblies. This O-ring is suited for use with petroleum products and mineral-based oils but should not be used in applications involving ozone-rich environments, direct sunlight exposure, or proximity to motors and other electrical equipment that may generate ozone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 018 standard sizing: 0.739 inches ID, 0.875 inches OD, 0.0625 inches thick\u003c\/li\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) material — the most widely used O-ring elastomer\u003c\/li\u003e\n\u003cli\u003eRated -40 degrees F to 250 degrees F operating temperature range\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to petroleum products, mineral oils, and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eRound cross section with hard (70 durometer) hardness rating for reliable compression set\u003c\/li\u003e\n\u003cli\u003eBlack color; sold in a package of 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and mineral-based fluid systems.

Shut off and depressurize the system completely before removing or installing any O-ring seal. Inspect the mating groove and sealing surface for damage or contamination before installing the new O-ring. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this will degrade the Buna-N material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.739 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.875 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: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 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: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.188 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH70MD018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690742513970,"sku":"ZMSCH70MD018","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51f0714b7cb258624cd767d42faa837.jpg?v=1788274789","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70md018-o-ring-dash-018-nbr-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
