It measures 2.375 inches inside diameter, 2.625 inches outside diameter, and 0.125 inches thick, with a round cross-section and a Shore A hardness of 70. Buna-N compound delivers excellent resistance to petroleum-based fluids, strong compression set recovery, and solid tear and abrasion resistance. This O-ring is installed by plumbers, HVAC technicians, hydraulic system mechanics, and industrial maintenance professionals wherever a reliable static or dynamic petroleum-fluid seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in hydraulic and pneumatic fittings, pump housings, valve bodies, and fluid line connections that handle petroleum products, oils, and fuels. It performs across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for both outdoor and heated-system environments. Sold in packages of 50, it is commonly stocked by shops running recurring preventive maintenance on compressors, pumps, and plumbing assemblies that use standard AN or SAE dash-size O-ring grooves.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound with excellent petroleum-product resistance\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 for reliable groove fill and compression set performance\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross-section, Dash 229 standard sizing per SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003eBlack color; package quantity of 50 units per order\u003c\/li\u003e\n\u003cli\u003eTear and abrasion resistant — suitable for dynamic as well as static sealing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit standard Dash 229 O-ring grooves per SAE and MIL-Spec dimensional standards.

Lightly lubricate the O-ring with a compatible petroleum-based or assembly lubricant before seating to prevent tearing during installation. Avoid rolling or twisting the O-ring into the groove; seat it evenly around the full circumference. Inspect the groove for burrs or corrosion before installation to avoid premature seal failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.625 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: 229\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: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70\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, oils, fuels\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\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: ZMSCH70229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699253641522,"sku":"ZMSCH70229","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5951ea1d7cd9082d32c4cd6e0be428c8.jpg?v=1788374188","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70229-buna-n-o-ring-dash-229","provider":"Voomi Supply","version":"1.0","type":"link"}
