CDV-CD8404 Copper Tube Access Valve 1/4 in 20 Pack

Product Description

The CDVALVECDVCD8404 C&DV-CD8404 is a braze-on copper tube access valve designed for use on 1/4-inch copper refrigerant lines. 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.

These 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.

Compatibility

Designed 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.

Installation Notes

Installation 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.
