It measures 0.796 inches inside diameter, 1.063 inches outside diameter, and 0.125 inches thick. Hardness is rated at 70 Shore A, placing it in the hard category. This O-ring seals against petroleum-based fluids and is used across a wide range of hydraulic, pneumatic, and fluid-handling systems. Licensed HVAC technicians, plumbers, and mechanical contractors install this type of seal during routine maintenance and equipment repair. It carries SAE and MIL-Spec standards compliance.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications where petroleum product resistance is required. Typical install scenarios include valve stems, pump shafts, fittings, and fluid connectors in HVAC, plumbing, and general mechanical assemblies. The Buna-N compound performs across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for most indoor and moderate outdoor service environments. The package contains 100 O-rings, supporting field stock and bulk replacement needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile butadiene rubber) compound offers excellent resistance to petroleum-based fluids and lubricants\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides reliable compression set performance in static and low-cycle dynamic applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F suits a broad range of service conditions\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 0.125 inches thickness conforms to standard Dash 211 groove dimensions\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards for dimensional and material consistency\u003c\/li\u003e\n  \u003cli\u003ePackage of 100 units supports inventory stocking and multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 211 replacement O-ring compatible with petroleum-product environments; suitable for use in HVAC, plumbing, and mechanical fluid-system applications requiring a 0.796 inches ID by 1.063 inches OD seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of O-rings in pressurized fluid systems should be performed by a qualified technician following applicable equipment manufacturer service procedures. Always depressurize and de-energize the system before disassembling any valve, pump, or fitting. Inspect the groove and mating surfaces for burrs or scoring before seating the new O-ring. Buna-N O-rings should not be stored in direct sunlight or near motors or electrical equipment that may generate ozone, as this degrades the elastomer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 211\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.796 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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 Material\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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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: 100\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: ZMSCH70211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716191486258,"sku":"ZMSCH70211","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddfb2317e6025cd59ad70d9effe34e1a.jpg?v=1788522925","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70211-o-ring-dash-211-nitrile-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
