It provides a reliable seal and load-bearing surface under fastener heads in plumbing, hydraulic, and mechanical assemblies where leak prevention is required. The washer features a 0.375 inch inside diameter, a 0.5625 inch outside diameter, and a 0.0312 inch thickness. Copper construction offers natural corrosion resistance and soft conformability, allowing the washer to compress slightly against mating surfaces to form a fluid-tight seal. Sold in a 100-piece pack. Installers working on fluid lines or fittings that require a sealing washer will find this a straightforward drop-in component.\u003c\/p\u003e\u003cp\u003eThis washer is suited for use in low-pressure plumbing connections, hydraulic fittings, fuel line joints, and general mechanical assemblies where a soft metal sealing element is needed. The inch-dimensioned sizing makes it compatible with standard inch-series fasteners and fittings commonly found in residential and light commercial mechanical systems. Trade professionals including plumbers and HVAC technicians routinely use copper sealing washers at compression fittings, drain plugs, and banjo-style hydraulic connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCopper material provides corrosion resistance and soft-metal sealing compression\u003c\/li\u003e\n\u003cli\u003ePlain finish — no coating to interfere with sealing surface contact\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.375 inches fits standard 3\/8 inch screws and bolts\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.5625 inches provides adequate bearing surface\u003c\/li\u003e\n\u003cli\u003eThickness of 0.0312 inches allows controlled compression at mating surfaces\u003c\/li\u003e\n\u003cli\u003e100-piece pack supports service truck stocking and maintenance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sealing washer for use with 3\/8 inch inch-series fasteners in plumbing, hydraulic, and mechanical assembly applications requiring a soft copper sealing element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or qualified mechanical tradespeople. Shut off and depressurize the fluid system before replacing sealing washers. Inspect mating surfaces for nicks or burrs that could prevent a proper seal. Copper sealing washers are typically single-use components and should be replaced rather than reused once compressed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Sealing Flat Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\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: 31161807\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: C613705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692789760306,"sku":"C613705","price":75.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47a016aec3398662e9d23b66a2d172a9.jpg?v=1788302927","url":"https:\/\/voomisupply.com\/products\/value-collection-c613705-copper-sealing-flat-washer-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
