It measures 0.875 inches inside diameter, 1.125 inches outside diameter, and 0.125 inches thick. The X cross section provides four sealing contact points instead of the two offered by a standard round cross section, reducing spiral twist and blow-out risk in dynamic and static sealing applications. It is rated for continuous service from -30 degrees F to 250 degrees F, making it suitable for petroleum-based fluid and hydraulic sealing tasks common in HVAC, plumbing, and mechanical systems.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and light commercial applications wherever a Dash 212 seal is required, including hydraulic fittings, refrigerant service ports, pump housings, valve stems, and fluid-transfer connections. The NBR compound performs well against petroleum oils, hydraulic fluids, fuels, and water. The X cross section is a common upgrade replacement for standard round cross section Dash 212 O-rings in gland seats already dimensioned for the 212 size. Sold in a package quantity of 100, making it practical for shop stock and recurring service use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eX-profile (quattro) cross section reduces spiral twist and improves stability in dynamic sealing grooves\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber compound provides strong resistance to petroleum oils, hydraulic fluids, and water\u003c\/li\u003e\n  \u003cli\u003e70 Shore A durometer provides firm hardness suitable for moderate-pressure sealing applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -30 degrees F to 250 degrees F covers a wide range of HVAC and mechanical service conditions\u003c\/li\u003e\n  \u003cli\u003eDash 212 standard dimensions allow direct fitment into glands designed for this industry-standard size\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 100 units supports shop stock and high-volume service operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-dimension replacement for any Dash 212 O-ring application where an X cross section profile is compatible with the existing gland geometry and NBR compound suits the media being sealed.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation is performed by plumbers, HVAC technicians, and hydraulic system mechanics as part of routine seal replacement. Before replacing an O-ring, shut off and depressurize the system completely. Lightly lubricate the O-ring with a compatible lubricant — use only lubricants compatible with NBR and the system fluid — to ease installation and reduce the risk of tearing. Never roll or force the O-ring over sharp threads or edges; use proper installation tools or a smooth-edged guide sleeve when needed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.8750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 212\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: X (Quattro)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurometer Shore A\u003c\/strong\u003e: 70\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: -30 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\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: ZMSCQH70212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692888555826,"sku":"ZMSCQH70212","price":37.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a886731714efd11588d802593d31ef56.jpg?v=1788304554","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscqh70212-o-ring-dash-212-nbr-70a","provider":"Voomi Supply","version":"1.0","type":"link"}
