Product Description

The MALCO CD8438 is a refrigerant access tee designed for HVAC service work on sealed refrigerant systems. It features a 1/4 inch male flare fitting mounted on a 3/8 inch OD tube body, with swaged ends on each side to accept 3/8 inch OD tubing. The valve core assembly uses a CD2250 brass wrench cap valve core, providing a reliable service port for system access during leak checks, evacuation, or refrigerant charging.
