Copper Line established top quality: Not All Copper Is made Equal
The time period “copper line set” Seems clear-cut, but right here’s the capture: copper purity and producing specifications fluctuate wildly. affordable imports usually use recycled copper with impurities that weaken the tubing and enable it to be susceptible to pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s made to the highest HVAC sector normal for seamless copper tube. That translates into:
-
bigger burst strain tolerance (significant for contemporary superior-pressure refrigerants like R-410A and R-32).
-
Better corrosion resistance, especially in coastal or industrial areas.
