The expression “copper line established” Seems uncomplicated, but right here’s the capture: copper purity and production criteria range wildly. inexpensive imports usually use recycled copper with impurities that weaken the tubing and help it become vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, meaning it’s built to the best HVAC sector regular for seamless copper tube. That translates into:
-
Higher burst tension tolerance (crucial for contemporary high-strain refrigerants like R-410A and R-32).
-
Better corrosion resistance, especially in coastal or industrial areas.
