The term “copper line set” Appears straightforward, but listed here’s the capture: copper purity and production expectations change wildly. affordable imports frequently use recycled copper with impurities that weaken the tubing and make it susceptible to pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s made to the highest HVAC industry typical for seamless copper tube. That interprets into:
-
Higher burst stress tolerance (vital for contemporary higher-tension refrigerants like R-410A and R-32).
-
much better corrosion resistance, particularly in coastal or industrial parts.
