It measures 1.313 inches inside diameter and 1.688 inches outside diameter with a 0.1875-inch (3\/16 inch) round cross-section thickness. Manufactured from Nitrile Butadiene Rubber (NBR) at a Shore A hardness of 70, this O-ring delivers reliable compression set resistance and strong resistance to petroleum-based fluids. Licensed plumbers, hydraulic technicians, and industrial mechanics install this type of seal to prevent fluid leakage at fittings, valves, and bore interfaces. Each package contains 25 pieces.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, hydraulic equipment, pneumatic tooling, and general industrial fluid-system maintenance where petroleum product exposure is expected. Its temperature rating spans -40 degrees F to 250 degrees F, making it appropriate for a wide range of service environments. The Buna-N compound is the most widely deployed O-ring elastomer in trade use due to its balance of cost, chemical compatibility, and mechanical durability. It is not intended for use with ozone-generating environments, strong solvents, or direct sunlight storage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (NBR) elastomer with excellent resistance to petroleum-based fluids and lubricants\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 rated Hard for reliable compression and leak-free sealing\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 for standard groove fitment per Dash 323 sizing\u003c\/li\u003e\n\u003cli\u003eGood tear and abrasion resistance for long service life in dynamic and static applications\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 323 replacement O-ring compatible with petroleum-based fluid systems including hydraulic, pneumatic, and plumbing assemblies that use AS568 standard groove dimensions for the 323 dash size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDe-pressurize and isolate the system before removing or installing any O-ring seal. Lightly lubricate the O-ring with a compatible petroleum-based or system-approved grease before seating to prevent rolling and tearing during assembly. Avoid storing Buna-N O-rings near electric motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade NBR over time. Installation is typically performed by licensed plumbers, hydraulic technicians, or qualified maintenance mechanics following applicable system service procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 323\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.688 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 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 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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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\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: ZMSCH70323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689549889842,"sku":"ZMSCH70323","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_fab0faed-b16c-40a4-a050-d6b63883a2f5.jpg?v=1788261195","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70323-o-ring-dash-323-nbr-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
