Copper Line established good quality: Not All Copper Is designed equivalent
The phrase “copper line established” Appears uncomplicated, but in this article’s the capture: copper purity and manufacturing expectations change wildly. low-cost imports normally use recycled copper with impurities that weaken the tubing and enable it to be prone to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s built to the highest HVAC industry conventional for seamless copper tube. That translates into:
-
larger burst tension tolerance (significant for contemporary superior-tension refrigerants like R-410A and R-32).
-
much better corrosion resistance, particularly in coastal or industrial parts.
