The expression “copper line set” sounds straightforward, but listed here’s the capture: copper purity and manufacturing expectations differ wildly. affordable imports usually use recycled copper with impurities that weaken the tubing and help it become at risk of pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s designed to the highest HVAC market normal for seamless copper tube. That translates into:
-
increased burst tension tolerance (essential for contemporary superior-force refrigerants like R-410A and R-32).
