It measures 3.63 inches inside diameter, 3.88 inches outside diameter, and 0.125 inches thick. With a durometer hardness of 70 Shore A and a working temperature range of -40 degrees F to 275 degrees F, this O-ring is built for reliable static and dynamic sealing in fluid and pneumatic systems. Licensed trades and maintenance professionals use NBR O-rings in HVAC equipment, plumbing assemblies, hydraulic fittings, and pneumatic components where petroleum-based fluids or water are present.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications where a Dash 239 standard-size seal is required. Typical install scenarios include pump housings, valve bodies, pipe unions, and fluid-handling manifolds. The NBR compound performs reliably in contact with oils, fuels, and water-based fluids across a broad service temperature range, making it a versatile replacement seal for general trade use. Minimum order quantity is 25 pieces; each package contains 1 unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (NBR) compound resists oils, fuels, and water-based fluids\u003c\/li\u003e\n  \u003cli\u003eDash 239 standard sizing for direct drop-in replacement\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent seating and even compression\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rated Hard for durable sealing under pressure\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 275 degrees F\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity of 25 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement seal for any application requiring a Dash 239 standard O-ring in NBR material, including pump housings, valve assemblies, and fluid-system fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance professionals. Always depressurize and drain the system before removing the old seal. Inspect the O-ring groove for nicks, burrs, or corrosion before seating the new ring. Apply a compatible, system-appropriate lubricant to ease installation and prevent twisting during assembly.\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 (NBR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 239\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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: 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ZBD9993-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709599744306,"sku":"ZBD9993-12","price":15.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a1c62941e840248bfe6472f0cd13461.jpg?v=1788458286","url":"https:\/\/voomisupply.com\/products\/value-collection-zbd9993-12-o-ring-dash-239-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
