Copper Line established high quality: Not All Copper Is designed equivalent
The time mini split line set period “copper line set” Appears uncomplicated, but right here’s the catch: copper purity and production requirements vary wildly. low-cost imports usually use recycled copper with impurities that weaken the tubing and enable it to be vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s built to the best HVAC marketplace regular for seamless copper tube. That translates into:
-
greater burst stress tolerance (critical for contemporary substantial-stress refrigerants like R-410A and R-32).
