It features a round cross-section profile and a Shore A hardness of 70, placing it in the hard hardness range. NBR is the most widely used O-ring elastomer in trade applications, offering excellent resistance to petroleum-based fluids, strong compression set resistance, and good tear and abrasion resistance. This package contains 10 O-rings. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of seal in fluid-handling assemblies across residential and commercial systems.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in hydraulic, pneumatic, and plumbing assemblies where petroleum product exposure is a factor. It performs across a service temperature range of -40 degrees F to 250 degrees F, making it appropriate for a wide range of heating, cooling, and fluid transfer applications. The Dash 212 designation is a standard AN\/AS568 size, commonly found in fittings, valve bodies, pump housings, and pipe unions. NBR compound is not recommended for exposure to ozone-generating sources such as electric motors or direct sunlight during storage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 212 standard size: 7\/8 inch ID, 1-1\/8 inch OD, 1\/8 inch thick\u003c\/li\u003e\n\u003cli\u003eNitrile butadiene rubber construction with excellent petroleum fluid resistance\u003c\/li\u003e\n\u003cli\u003eShore A 70 hardness for reliable compression set in standard mechanical joints\u003c\/li\u003e\n\u003cli\u003eRated for service temperatures from -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for consistent sealing in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 10 for job-site and shop inventory use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AN\/AS568 Dash 212 O-ring replacement compatible with petroleum-based fluid systems.

Always depressurize and de-energize the system before replacing O-rings in any fluid or refrigerant circuit. Clean the groove and mating surfaces before seating the O-ring, and avoid twisting or pinching the ring during installation. Do not store NBR O-rings near electric motors, ozone-generating equipment, or in direct sunlight, as ozone exposure degrades the elastomer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 212\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\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 Fluids\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: 10\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: ZMSCH70MD212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694636335410,"sku":"ZMSCH70MD212","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_bab39514-3f13-4748-b541-8c0974acb86c.jpg?v=1788326571","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70md212-o-ring-dash-212-nbr-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
