Copper Line Set Quality: Not All Copper Is produced Equal
The term “copper line established” sounds simple, but in this article’s the catch: copper purity and manufacturing criteria differ wildly. inexpensive imports generally 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, that means it’s produced to the highest HVAC market common for seamless copper tube. That translates into:
-
bigger burst stress tolerance (critical for modern large-stress refrigerants like R-410A and R-32).
-
improved corrosion resistance, specifically in coastal or industrial locations.
