It provides a service port for refrigerant charging, evacuation, and system diagnostics without requiring a permanent line tap or Schrader-style piercing tool. The fitting includes a 1\/4-inch male flare access port and a copper tube extension for direct brazing onto the line. A brass cap and valve core are included with each piece. This listing covers a bulk pack of 20 valves, sold unpackaged.\u003c\/p\u003e\u003cp\u003eThese access valves are used in residential and light commercial HVAC and refrigeration service work. They are a standard field addition when a service technician needs a gauge port on a system that lacks one, or when an existing access fitting is damaged or missing. The braze-on design makes them suitable for permanent installation on suction or liquid lines where a secure, leak-free connection is required. Sold in a 20-piece bulk quantity, they are a practical stock item for service vans and shop inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBraze-on installation onto 1\/4-inch copper tubing for a permanent, leak-free service port\u003c\/li\u003e\n\u003cli\u003e1\/4-inch male flare access fitting for standard refrigerant hose connections\u003c\/li\u003e\n\u003cli\u003eCopper tube extension included for direct integration into the refrigerant line\u003c\/li\u003e\n\u003cli\u003eBrass cap included to protect the valve core and maintain system pressure when not in service\u003c\/li\u003e\n\u003cli\u003eValve core included — ready to install without sourcing additional hardware\u003c\/li\u003e\n\u003cli\u003eBulk pack of 20 pieces for service fleet and shop stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style braze-on access valve for 1\/4-inch copper refrigerant tubing commonly found in residential and light commercial HVAC and refrigeration systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians using standard brazing equipment. Recover all refrigerant and depressurize the system before brazing to avoid ignition risk and to meet EPA Section 608 requirements. Use nitrogen purge during brazing to prevent copper oxide scaling inside the line. After installation, leak-check all brazed joints before recharging the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 1\/4 inch Male Flare with Copper Tube Extension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Brass Cap, Valve Core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Purchase\u003c\/strong\u003e: 20 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Braze-On\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CDVALVECDVCD8404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C\u0026amp;DV-CD8404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"C\u0026D VALVE","offers":[{"title":"Default Title","offer_id":51524802347314,"sku":"C\u0026DV-CD8404","price":26.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99444bad670a2f8af3aeabf2a351fae1.jpg?v=1785458021","url":"https:\/\/voomisupply.com\/products\/cdv-cd8404-copper-tube-access-valve-1-4-in-20-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
