The time period “copper line set” Appears simple, but here’s the capture: copper purity and manufacturing specifications vary wildly. low-priced imports generally use recycled copper with impurities that weaken the tubing and make it liable to pinhole leaks.
Our copper is ASTM B280 compliant, meaning it’s designed to the highest HVAC marketplace typical here for seamless copper tube. That interprets into:
-
bigger burst force tolerance (vital for contemporary large-force refrigerants like R-410A and R-32).
-
much better corrosion resistance, especially in coastal or industrial areas.
