CDV-CD8428 Copper Tee Fitting 5/8 in Od Male Flare Access

Product Description

The CDV-CD8428 is a copper tee fitting designed for use in HVAC/R refrigerant line applications. It features a 1/4 inch male flare access port that provides a convenient service point for refrigerant charging, pressure testing, or system diagnostics without cutting into the main line. The tee body is built on 5/8 inch outer diameter (OD) copper tube stock measuring 3 inches in length. This type of fitting is typically installed by licensed HVAC/R technicians working on split systems, heat pumps, or commercial refrigeration circuits where periodic line access is required.

The CDV-CD8428 is suited for residential and light commercial HVAC/R systems that use 5/8 inch OD copper refrigerant tubing. The integrated 1/4 inch male flare access port follows standard flare fitting geometry, making it compatible with common service valves, hose manifolds, and gauge sets used in the field. It is appropriate for new installations and retrofit service situations where a permanent access point needs to be added to an existing refrigerant circuit.

Key Features

• 1/4 inch male flare access port for direct manifold gauge or service valve connection
• 5/8 inch OD copper tube construction for reliable, leak-resistant refrigerant line integration
• 3 inch tube length provides clearance for brazing without heat damage to the access port
• Tee configuration allows inline installation without interrupting the main refrigerant circuit
• Copper material is compatible with common refrigerants used in HVAC/R systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for HVAC/R systems using 5/8 inch OD copper refrigerant tubing with a 1/4 inch male flare service port requirement.

Installation Notes

Installation should be performed by a licensed HVAC/R technician in accordance with applicable mechanical codes. The refrigerant system must be recovered and the circuit depressurized before brazing or modifying any refrigerant line. Use appropriate brazing alloy and shield the flare access port fitting body from direct flame during the brazing process to protect the valve seat and seals. After installation, pressure-test the joint and verify for leaks before recharging the system.
