The expression “copper line set” Seems easy, but in this article’s the capture: copper purity and producing expectations fluctuate wildly. Cheap imports typically use recycled copper with impurities that weaken the tubing and allow it to be at risk of pinhole leaks.
Our copper is ASTM B280 compliant, which means it’s built to the best HVAC field common for seamless copper tube. That translates into:
-
greater burst strain tolerance (essential for modern large-force refrigerants like R-410A and R-32).
-
far better corrosion resistance, particularly in coastal or industrial places.
