Copper Line Set Quality: Not All Copper Is established Equal
The time period “copper line established” Appears simple, but right here’s the catch: copper purity and production specifications change wildly. Cheap imports typically use recycled copper with impurities that weaken the tubing and ensure it is vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s built to the highest HVAC industry regular for seamless copper tube. That interprets into:
-
bigger burst strain tolerance (important for contemporary substantial-stress refrigerants like R-410A and R-32).
-
superior corrosion resistance, specifically in coastal or industrial places.
