Copper Line established high quality: Not All Copper Is established Equal
The expression “copper line set” Seems simple, but in this article’s the capture: copper purity and manufacturing specifications differ wildly. low-cost imports usually use recycled copper with impurities that weaken the tubing and ensure it is liable to pinhole leaks.
Our copper is ASTM B280 compliant, which means it’s built to the very best HVAC business standard for seamless copper tube. That translates into:
-
larger burst force tolerance (vital for modern higher-force refrigerants like R-410A and R-32).
-
far better corrosion resistance, particularly in coastal or industrial regions.

Smoother inside surfaces, which retain refrigerant circulation successful and oil return regular.
