Manufactured from Buna-N elastomer with a Shore hardness of 90 durometer, this o-ring provides extra-hard compression set resistance and strong tear and abrasion performance. It is rated for service from -40 degrees F to 250 degrees F and is compatible with petroleum-based fluids. Plumbers, HVAC technicians, and industrial maintenance mechanics install this type of seal in hydraulic fittings, fluid connectors, and mechanical assemblies where reliable static or dynamic face sealing is required.\u003c\/p\u003e\n\u003cp\u003eThis o-ring suits residential and commercial applications involving petroleum-product fluid systems, including hydraulic lines, fuel system fittings, and general-purpose pipe and valve connections. The Buna-N compound is the most widely used o-ring elastomer in HVAC, plumbing, and fluid-power trades. Each package contains 50 pieces, making it a practical stocking unit for service vans or shop inventory. The Dash 224 designation conforms to standard AS568 sizing, allowing straightforward cross-referencing with groove dimensions specified on system drawings or OEM service manuals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003e90 durometer Shore hardness rated Extra Hard for high-compression seal applications\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile; 0.125-inch (3.53 mm) thickness per Dash 224 AS568 standard\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 pieces per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based fluids and hydraulic media.

Depressurize and drain the system completely before removing the old seal or installing a new one. Lightly lubricate the o-ring with a compatible petroleum-based or system-approved lubricant before seating it in the groove to prevent twisting or nicking during assembly. Store unused o-rings away from direct sunlight, ozone sources, and electrical equipment that may generate ozone, as these conditions degrade Buna-N elastomer over time.\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: 224\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.75 inches (44.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 mm)\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: 90 Shore A (Extra 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\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: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.97 pounds\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: ZMSCH90224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723987714354,"sku":"ZMSCH90224","price":15.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_85fffcbc-8572-4689-b702-18a654e5f91a.jpg?v=1788611124","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90224-o-ring-dash-224-nbr-pack-50","provider":"Voomi Supply","version":"1.0","type":"link"}
