The time period “copper line established” Seems easy, but in this article’s the capture: copper purity and producing requirements change wildly. low-priced imports typically use recycled copper with impurities that weaken the tubing and enable it to be liable to pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s made to the very best HVAC business normal for seamless copper tube. That translates into:
-
better burst strain tolerance (important for contemporary high-strain refrigerants like R-410A and R-32).
-
improved corrosion resistance, particularly in coastal or industrial areas.
