Copper Line Set top quality: Not All Copper Is designed equivalent
The phrase “copper line established” Seems uncomplicated, but right here’s the capture: copper purity and production specifications change wildly. low cost imports usually use recycled copper with impurities that weaken the tubing and make it at risk of pinhole leaks.
Our copper is ASTM B280 compliant, which means it’s made to the best HVAC field conventional for seamless copper tube. That interprets into:
-
larger burst force tolerance (critical for modern substantial-tension refrigerants like R-410A and R-32).
