Copper Line Set high quality: Not All Copper Is made equivalent
The expression “copper line set” Seems clear-cut, but here’s the capture: copper purity and producing criteria change wildly. affordable imports usually use recycled copper with impurities that weaken the tubing and allow it to be vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s manufactured to the highest HVAC marketplace conventional for seamless copper tube. That interprets into:
-
bigger burst stress tolerance (important for contemporary significant-stress refrigerants like R-410A and R-32).
-
greater corrosion resistance, especially in coastal or industrial regions.
