The expression “copper line established” Seems clear-cut, but in this article’s the catch: copper purity and manufacturing requirements range wildly. low-cost imports generally use recycled copper with impurities that weaken the tubing and help it become liable to pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s manufactured to the highest HVAC field standard for seamless copper tube. That interprets into:
-
larger burst force tolerance (essential for modern substantial-stress refrigerants like R-410A and R-32).
-
Better corrosion resistance, especially in coastal or industrial locations.
