ACR copper straight coupling for refrigeration and HVAC pipe connections. High-purity C12200 copper, ASME B16.22 compliant. Sweat-end design for secure solder joints. Sizes 1/4″ to 4 1/8″ OD. Corrosion resistant, leak-proof.
Our Copper Straight Coupling is a precision-engineered pipe fitting designed to connect two lengths of copper tubing in a straight line for air conditioning, refrigeration, and heat pump systems. Manufactured from high-purity phosphorus-deoxidized copper (C12200), it provides a secure, leak-proof joint that withstands the pressure and temperature demands of ACR applications.
The coupling features a sweat-end (solder cup) design that allows for easy brazing or soldering during installation. Its seamless, one-piece construction eliminates potential leak paths found in welded or assembled fittings, ensuring reliable long-term performance in refrigerant circuits.
