This O-ring measures 2.5 inches inside diameter, 2.688 inches outside diameter, and 0.0937 inches thick with a round cross section. It carries a hardness rating of 70 Shore A, placing it in the hard range for reliable compression set resistance. Plumbers, HVAC technicians, and mechanical contractors install this type of O-ring to seal hydraulic, pneumatic, and petroleum-fluid connections where consistent static or dynamic sealing is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, HVAC refrigerant and oil circuits, hydraulic assemblies, and general industrial fluid systems that use petroleum-based media. Its Buna-N compound delivers excellent resistance to petroleum products, fuels, and oils, making it a standard choice for pump seals, valve stems, pipe unions, and fitting connections. The part is sold in a package quantity of 50 units, supporting shop-stock replenishment and service fleet inventory. Minimum order quantity is 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum products, hydraulic oils, and fuels\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 0.0937-inch thickness for consistent gland fill and seal integrity\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness provides strong compression set and tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage of 50 units supports shop stock and multi-unit service work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids. Designed for use in standard AS568 Dash 144 O-ring gland dimensions. Do not use with ozone-generating equipment, direct sunlight exposure environments, or media incompatible with Nitrile rubber. This part is not FDA approved and is not intended for food-contact applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Shut off and depressurize the system fully before removing the old O-ring and inspecting the gland for wear or damage. Lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent pinching or tearing during installation. Do not store unused O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade Nitrile rubber 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: 144\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.688 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\u003eCross Section Shape\u003c\/strong\u003e: Round\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 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCH70144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690750476594,"sku":"ZMSCH70144","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/422714dfff1d53a139da71db819eb9fc.jpg?v=1788274952","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70144-o-ring-2-5-in-id-nitrile-dash-144","provider":"Voomi Supply","version":"1.0","type":"link"}
