Our copper is ASTM B280 compliant, meaning it’s produced to the best HVAC business standard for seamless copper tube. That interprets into:
-
larger burst pressure tolerance (crucial for contemporary substantial-force refrigerants like R-410A and R-32).
-
superior corrosion resistance, especially in coastal or industrial regions.
