The expression “copper line established” Appears clear-cut, but right here’s the capture: copper purity and producing specifications range wildly. inexpensive imports frequently use recycled copper with impurities that weaken the tubing and help it become vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s built to the best HVAC market regular for seamless copper tube. That translates into:
-
larger burst force tolerance (vital for contemporary superior-tension refrigerants like R-410A and R-32).
-
improved corrosion resistance, particularly in coastal or industrial locations.
