"3/8 Service Port"

The 3/8″ Copper Access Valve is a high-flow service port designed for larger refrigeration systems and commercial HVAC applications. Featuring a larger 3/8″ SAE Flare connection, this valve allows for significantly faster vacuum pull-downs and refrigerant charging compared to standard 1/4″ valves. The 4-inch high-purity copper stem provides ample space for secure brazing into suction lines or large evaporator coils, making it an essential component for heavy-duty cooling maintenance.
