7/8 to 5/8 Inch

Precision-engineered copper reducing coupling designed to transition seamlessly between 7/8-inch and 5/8-inch copper tubing lines in HVAC systems. Forged from high-purity seamless copper, it ensures excellent structural strength, high thermal conductivity, and superior resistance to system corrosion. The stepped interior profile facilitates a snug slip-on fit for both tube sizes, enabling uniform solder flow and a permanently leak-proof joint. Essential for adapting line sizes across different commercial and residential cooling configurations.
