It features an inside diameter of 2.1875 inches, an outside diameter of 2.38 inches, and a thickness of 0.0937 inches. Manufactured from Viton fluoroelastic material, this O-ring delivers strong resistance to heat, fuels, hydraulic fluids, and a wide range of chemicals. It carries a hardness rating of 75 Shore A, placing it in the hard durometer range. Licensed tradespeople and maintenance technicians working with fluid handling, pneumatic, or mechanical sealing systems will find this a reliable replacement or service part.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications across HVAC, plumbing, industrial fluid systems, and hydraulic assemblies where elevated temperatures or chemical exposure are present. The Viton compound supports continuous service between -15 degrees F and 400 degrees F, making it appropriate for demanding environments where standard nitrile or EPDM compounds would degrade. It ships individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eViton fluoroelastic material resists fuels, oils, hydraulic fluids, and many solvents\u003c\/li\u003e\n\u003cli\u003eOperating temperature range from -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section profile for consistent sealing contact\u003c\/li\u003e\n\u003cli\u003e75 Shore A hardness for firm, reliable compression under load\u003c\/li\u003e\n\u003cli\u003eConforms to Dash 139 standard sizing for straightforward cross-referencing\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 139 O-ring replacement for grooves and fittings dimensioned to accept a 2.1875-inch ID by 2.38-inch OD by 0.0937-inch thick round-cross-section seal in Viton material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with the system being serviced. Depressurize and isolate the assembly before removing the old O-ring, and clean the groove thoroughly to remove debris or old sealing compound. Lightly lubricate the O-ring with a compatible fluid or grease before seating to avoid tearing during installation. Do not use petroleum-based lubricants on Viton O-rings unless confirmed compatible with the system media.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Viton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 139\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 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: 75 Shore A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: ZBD9500-139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716380950834,"sku":"ZBD9500-139","price":23.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d8384c3e8bd0f5376a76d59e67ba4e_473cf5e0-3588-4071-b678-02ce4eb7be3f.jpg?v=1788525199","url":"https:\/\/voomisupply.com\/products\/value-collection-zbd9500-139-viton-o-ring-dash-139","provider":"Voomi Supply","version":"1.0","type":"link"}
