It measures 1.625 inches inside diameter, 1.750 inches outside diameter, and 0.0625 inches thick. With a Shore A hardness of 70, this elastomer delivers firm compression set and solid resistance to petroleum-based fluids, hydraulic oils, and fuels. Rated for service from -40 degrees F to 250 degrees F, it holds its seal across a wide operating range. This is the most widely used O-ring elastomer in trade applications.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial service work involving petroleum products, hydraulic circuits, fuel lines, and general fluid sealing. Plumbers, HVAC technicians, and equipment service techs commonly use Dash 030 Buna-N O-rings when servicing valves, fittings, pumps, and compressor connections. The pack quantity of 100 units makes it practical for service vehicles and shop stock. Compatible with petroleum-based media. Not recommended for exposure to ozone-generating equipment or prolonged direct sunlight during storage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — excellent resistance to petroleum products, hydraulic fluids, and fuels\u003c\/li\u003e\n\u003cli\u003eDash 030 sizing: 1.625 inches ID, 1.750 inches OD, 0.0625 inches thick\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 — rated Hard for reliable compression set\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent sealing contact\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003ePack of 100 units for shop stock or field inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids.

Shut off all fluid supply and relieve system pressure completely before removing any fitting or valve seat. Inspect the O-ring groove for scoring or debris before seating the new ring. Do not store unused O-rings near motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade Buna-N over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 030\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.750 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\u003eShore A Hardness\u003c\/strong\u003e: 70 (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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\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: ZMSCH70030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699144655154,"sku":"ZMSCH70030","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20ea5530b0aefece16cccc3251804381.jpg?v=1788372714","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70030-nitrile-o-ring-dash-030-pack-100","provider":"Voomi Supply","version":"1.0","type":"link"}
