It measures 8 inches inside diameter, 8.375 inches outside diameter, and 0.1875 inches (3\/16 inches) thick with a round cross section. Hardness is rated at 70 Shore A, placing it in the hard range for reliable compression set performance. Buna-N compound delivers excellent resistance to petroleum-based fluids along with strong tear and abrasion resistance, making this O-ring a dependable choice for hydraulic, pneumatic, and fluid-handling sealing tasks. Each order ships in a pack of 5 pieces.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in hydraulic cylinders, pump housings, valve bodies, and fluid fittings where petroleum-product exposure is present. Typical applications include industrial machinery, plumbing assemblies, HVAC equipment, and other mechanical systems requiring a large-diameter face seal or piston seal. The operating temperature range of -40 degrees F to 250 degrees F covers most ambient and moderate-heat service conditions. It is not intended for use with ozone-generating environments, strong oxidizers, or ketone-based fluids.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — excellent petroleum product compatibility\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for reliable compression set and sealing force\u003c\/li\u003e\n  \u003cli\u003eRound cross section at 0.1875 inches thick for standard O-ring groove fitment\u003c\/li\u003e\n  \u003cli\u003eWide 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\u003ePack of 5 units per order with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Dash 369 replacement O-ring for any application requiring an 8-inch ID, 8.375-inch OD, 3\/16-inch cross section seal in systems compatible with Buna-N elastomer. Compatible with petroleum-based fluids and lubricants; not compatible with ozone, direct sunlight exposure during storage, or fluids that degrade nitrile compounds.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, hydraulic technician, or HVAC mechanic depending on the host system. Always depressurize and de-energize the system fully before removing the old seal. Lightly lubricate the O-ring with a compatible petroleum-based grease before seating it to prevent rolling or tearing during assembly. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as ozone exposure degrades nitrile compounds over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 369\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 8 inches (8.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8.375 inches (8-3\/8 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: 5 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\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: ZMSCH70369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698245959986,"sku":"ZMSCH70369","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68c3d63ce5241ac0e3ed02d2f8baa197.jpg?v=1788360009","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70369-o-ring-dash-369-nitrile-70a-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
