It measures 0.239 inches inside diameter and 2.518 inches outside diameter with a 0.064-inch cross-section thickness. The compound is rated at 90 durometer, placing it in the extra-hard hardness range, and it maintains a reliable seal from -40 degrees F up to 250 degrees F. Its round cross-section profile and consistent dimensional tolerances make it a dependable replacement seal for trade professionals working on petroleum-fluid systems.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and light commercial applications involving petroleum-based fluids, hydraulic systems, fuel lines, and pneumatic fittings. HVAC technicians, plumbers, and fluid-systems mechanics will encounter this size in compressor fittings, valve bodies, and threaded port connections where a static or low-motion seal is required. The Buna-N compound offers excellent resistance to petroleum products, strong compression set performance, and solid tear and abrasion resistance under normal service conditions. It should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound delivers excellent resistance to petroleum-based fluids and lubricants\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating provides firm, stable sealing under compression\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F suits most HVAC and fluid-system environments\u003c\/li\u003e\n\u003cli\u003eDash 902 standard sizing ensures dimensional interchangeability with OEM and aftermarket components\u003c\/li\u003e\n\u003cli\u003eRound cross-section with 0.064-inch thickness fits standard O-ring grooves designed for this dash number\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards for sealing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 902 replacement O-ring for use in petroleum-product-compatible sealing applications including hydraulic, fuel, and pneumatic systems that call for a Buna-N elastomer with a 90 durometer hardness rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with sealing procedures for the applicable system. Always depressurize and isolate the line or component before removing the old O-ring or installing a replacement. Lightly lubricate the O-ring with a compatible petroleum-based or system-approved lubricant prior to seating to reduce the risk of tearing during assembly. Avoid using sharp tools that may nick the sealing surface or the O-ring itself.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.239 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.518 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 0.064 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 902\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\u003eCross-Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 90 durometer (Extra 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 Fluid Types\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\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: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: ZMSCH90902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709353525554,"sku":"ZMSCH90902","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63e5be40384736fb1f090e4d0cdd585_209b295e-06d9-4a23-9c2a-359df68bb6a3.jpg?v=1788455098","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90902-o-ring-dash-902-nitrile","provider":"Voomi Supply","version":"1.0","type":"link"}
