5/8 to 3/8 Inch

High-quality copper reducing coupling engineered for reliable pipe size transitions between 5/8-inch and 3/8-inch copper tubing lines. Constructed from durable, premium-grade copper, it provides outstanding resistance to vibration fatigue and refrigerant-induced wear. The precise dual-diameter socket design ensures smooth tube insertion and even capillary attraction during torch brazing, creating a dependable, high-pressure seal. An indispensable component for contractors modifying or expanding refrigeration and air conditioning networks.
