Copper Line established high quality: Not All Copper Is established equivalent
The expression “copper line set” Appears straightforward, but below’s the capture: copper purity and production benchmarks range wildly. low-cost imports typically use recycled copper with impurities that weaken the tubing and ensure it is vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s created to the very best HVAC marketplace common for seamless copper tube. That interprets into:
-
bigger burst force tolerance (vital for modern significant-force refrigerants like R-410A and R-32).
