Copper Line Set excellent: Not All Copper Is established equivalent
The term “copper line established” Seems simple, but in this article’s the catch: copper purity and production standards fluctuate wildly. inexpensive imports usually use recycled copper with impurities that weaken the tubing and enable it to be susceptible to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s designed to the very best HVAC marketplace typical for seamless copper tube. That translates into:
-
Higher burst force tolerance (essential for contemporary significant-force refrigerants like R-410A and R-32).
-
improved corrosion resistance, specifically in coastal or industrial areas.
