Our copper is ASTM B280 compliant, this means it’s designed to the highest HVAC market conventional for seamless copper tube. That interprets into:
-
increased burst strain tolerance (significant for contemporary significant-strain refrigerants like R-410A and R-32).
-
improved corrosion resistance, especially in coastal or industrial spots.
