Copper Line established excellent: Not All Copper Is Created Equal
The term “copper line established” Seems straightforward, but below’s the capture: copper purity and producing benchmarks change wildly. low-priced imports generally use recycled copper with impurities that weaken the tubing and ensure it is susceptible to pinhole leaks.
Our copper is ASTM B280 compliant, meaning it’s made to the best HVAC business conventional for seamless copper tube. That translates into:
-
greater burst force tolerance (significant for contemporary significant-force refrigerants like R-410A and R-32).
-
much better corrosion resistance, especially in coastal or industrial parts.
