Our copper is ASTM B280 compliant, this means it’s designed to the highest HVAC field common for seamless copper tube. That translates into:
-
bigger burst tension tolerance (essential for modern higher-tension refrigerants like R-410A and R-32).
-
far better corrosion resistance, particularly in coastal or industrial locations.
