Our copper is ASTM B280 compliant, indicating it’s produced to the highest HVAC market typical for seamless copper tube. That interprets into:
-
bigger burst stress tolerance (vital for contemporary higher-force refrigerants like R-410A and R-32).
-
far better corrosion resistance, specifically in coastal or industrial spots.
