The term “copper line set” Seems clear-cut, but right here’s the capture: copper purity and manufacturing criteria differ wildly. affordable imports usually use recycled copper with impurities that weaken the tubing and ensure it is liable to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s produced to the highest HVAC field conventional for seamless copper tube. That translates into:
-
larger burst pressure tolerance (essential for contemporary high-pressure refrigerants like R-410A and R-32).
