1-3/8 to 1-1/2 Inch

Precision-crafted copper reducing coupling tailored for linking 1-3/8 inch and 1-1/2 inch copper lines in demanding cooling systems. Built from high-purity copper, it provides high resistance to thermal shock, corrosion, and continuous system working pressures. The exact socket fit simplifies on-site torch brazing, helping technicians achieve a clean, permanent, and hermetic seal quickly. Ideal for professional service work and custom heavy-duty piping configurations.
