The phrase “copper line established” Appears easy, but listed here’s the capture: copper purity and production specifications fluctuate wildly. low cost imports normally use recycled copper with impurities that weaken the tubing and allow it to be at risk of pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s created to the very best HVAC marketplace regular for seamless copper tube. That interprets into:
-
greater burst stress tolerance (vital for contemporary high-strain refrigerants like R-410A and R-32).
