The phrase “copper line set” sounds simple, but in this article’s the capture: copper purity and producing specifications differ wildly. affordable imports typically use recycled copper with impurities that weaken the tubing and allow pre charged line set it to be liable to pinhole leaks.
Our copper is ASTM B280 compliant, which means it’s manufactured to the highest HVAC industry standard for seamless copper tube. That translates into:
- 
        
larger burst force tolerance (critical for modern substantial-pressure refrigerants like R-410A and R-32).
 - 
        
greater corrosion resistance, specifically in coastal or industrial parts.
 -
