Copper Line established high-quality: Not All Copper Is produced Equal
The phrase “copper line set” Seems clear-cut, but right here’s the capture: copper purity and producing benchmarks range wildly. inexpensive imports often use recycled copper with impurities that weaken the tubing and enable it to be liable to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s built to the best HVAC business standard for seamless copper tube. That interprets into:
-
greater burst stress tolerance (essential for modern superior-stress refrigerants like R-410A and R-32).
-
far better corrosion resistance, especially in coastal or industrial regions.
