The term “copper line established” Seems uncomplicated, but below’s the catch: copper purity and manufacturing criteria differ wildly. low cost imports normally use recycled copper with impurities that weaken the tubing and allow it to be prone to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s manufactured to the best HVAC field standard for seamless copper tube. That interprets into:
-
larger burst force tolerance (important for modern substantial-force refrigerants like R-410A and R-32).
