The phrase “copper line set” Appears clear-cut, but here’s the catch: copper purity and producing benchmarks differ wildly. low-priced 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, that means it’s created to the highest HVAC industry regular for seamless copper tube. That interprets into:
-
increased burst strain tolerance (essential for contemporary superior-strain refrigerants like R-410A and R-32).
