It features an 8.75-inch inside diameter, a 9-inch outside diameter, and a 0.125-inch round cross-section thickness. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. It is installed by plumbers, HVAC technicians, and industrial maintenance professionals wherever a dependable petroleum-resistant static or dynamic seal is required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic systems, pneumatic equipment, fluid transfer lines, and general plumbing assemblies where exposure to petroleum-based oils, fuels, and lubricants is expected. Its operating temperature range of -40 degrees F to 250 degrees F makes it appropriate for a wide range of residential and light commercial service environments. It is sold in a package of 5 units, making it practical for technicians who service multiple systems in a single call. NBR compounds should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (NBR) construction offers excellent resistance to petroleum products including oils, fuels, and lubricants\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides a firm, reliable seal with strong compression set resistance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile conforms to standard Dash 269 groove dimensions\u003c\/li\u003e\n  \u003cli\u003eOperating range of -40 degrees F to 250 degrees F suits a broad range of service conditions\u003c\/li\u003e\n  \u003cli\u003eTear and abrasion resistance extends service life in dynamic and static applications\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards for dimensional and material compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 269 O-ring replacement compatible with petroleum-based fluid systems including hydraulic, pneumatic, and general plumbing assemblies requiring an 8.75-inch ID sealing element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Relieve all system pressure and drain fluid before removing the old O-ring and installing the replacement. Lubricate the O-ring with a compatible petroleum-based or silicone grease to ease seating and reduce risk of tearing during installation. Avoid twisting or rolling the O-ring into the groove, as this can compromise the seal integrity under pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 8.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 269\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: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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\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: 5\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: ZMSCH70269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692667797810,"sku":"ZMSCH70269","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab22228f4e2cda8e2060986e92c1f1fb.jpg?v=1788300869","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70269-o-ring-dash-269-nbr-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
