Hardness is rated at 70 Shore A, placing it in the hard range for elastomers. NBR is the most widely used O-ring elastomer in trade applications, valued for its excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. Each order ships as a pack of 25 rings. This part is used by HVAC technicians, plumbers, and mechanical contractors working on fluid and gas sealing applications.\u003c\/p\u003e\n\u003cp\u003eThe ZMSCH70MD112 is suited for static and dynamic sealing applications in systems that handle petroleum products, oils, fuels, and hydraulic fluids. Typical install scenarios include pump fittings, valve bodies, compressor ports, and threaded connections in residential and light commercial mechanical systems. The -40 degrees F minimum working temperature and 250 degrees F maximum working temperature make this ring appropriate for a broad range of service conditions encountered in HVAC, plumbing, and refrigeration work. This O-ring is not FDA approved and should not be used in food-contact or medical applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitrile butadiene rubber construction provides excellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 70 Shore A hardness for reliable sealing under compression\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits most HVAC and plumbing service environments\u003c\/li\u003e\n  \u003cli\u003eStrong tear and abrasion resistance extends service life in dynamic sealing applications\u003c\/li\u003e\n  \u003cli\u003eStore away from direct sunlight, motors, and electrical equipment that may generate ozone to prevent premature degradation\u003c\/li\u003e\n  \u003cli\u003ePack of 25 rings per package supports service stock and batch repairs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service O-ring for applications requiring a Dash 112 NBR seal compatible with petroleum products and oils.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or pipefitters. Always depressurize and isolate the system before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid prior to installation to prevent pinching or rolling during assembly. Inspect the seating groove for damage or debris before installing the new ring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.487 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 112\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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 Fluid Types\u003c\/strong\u003e: Petroleum Products\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: 0.26 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6 inches L x 4 inches W x 1 inch H\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: ZMSCH70MD112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722588356914,"sku":"ZMSCH70MD112","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b1cb94bb9896405319b6425fa7183ce.jpg?v=1788593199","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70md112-o-ring-dash-112-nbr-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
