It measures 3-1\/8 inches inside diameter and 3\/16 inches thick, with a durometer hardness of 70 Shore A. NBR compound provides reliable resistance to petroleum-based fluids, making this O-ring well suited for sealing applications in hydraulic, pneumatic, plumbing, and HVAC systems where oil and fuel exposure is common. Plumbers, HVAC technicians, and mechanical service professionals install this type of seal as a static or dynamic sealing element in fittings, valves, pumps, and manifolds.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for residential and light commercial maintenance and repair work wherever a Dash 338 inch-series O-ring is specified. Typical install scenarios include valve stem seals, pipe union joints, pump housings, and refrigeration service fittings. The NBR material performs across a broad service temperature range and maintains a consistent seal under moderate pressure, making it a practical replacement seal for general trade use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 338 inch-series O-ring for standardized replacement fitment\u003c\/li\u003e\n  \u003cli\u003e3-1\/8 inches inside diameter with 3\/16 inches cross-section thickness\u003c\/li\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (NBR) construction for petroleum-fluid resistance\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003e70 Shore A durometer for balanced flexibility and compression resistance\u003c\/li\u003e\n  \u003cli\u003eInch system of measurement for compatibility with standard U.S. trade fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 338 inch-series O-ring replacement for use in valves, fittings, pumps, and mechanical assemblies requiring a 3-1\/8 inches ID NBR seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical trade professional. Depressurize and isolate the system before removing the old seal, and inspect the O-ring groove for debris, burrs, or corrosion before seating the new ring. Apply a compatible lubricant to the O-ring before installation to prevent twisting or tearing during assembly. Do not overstretch the O-ring during installation, as deformation will compromise the seal.\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: 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 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\u003eDurometer\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage 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\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: BDNA--9994-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718634897714,"sku":"BDNA--9994-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff1c0c379ba7d85f4df42f5c0dede539.jpg?v=1788554707","url":"https:\/\/voomisupply.com\/products\/value-collection-bdna-9994-6-o-ring-dash-338-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
