The phrase “copper line set” Appears simple, but right here’s the capture: copper purity and production requirements change wildly. low-priced imports often use recycled copper with impurities that weaken the tubing and ensure it is at risk of pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s made to the highest HVAC industry conventional for seamless copper tube. That translates into:
-
better burst strain tolerance (vital for modern high-pressure refrigerants like R-410A and R-32).
-
