Copper Line Set excellent: Not All Copper Is produced equivalent
The term “copper line set” Appears straightforward, but below’s the catch: copper purity and producing specifications change wildly. low-cost imports normally use recycled copper with impurities that weaken the tubing and ensure it is at risk of pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s made to the very best HVAC field typical for seamless copper tube. That interprets into:
-
bigger burst strain tolerance (vital for modern high-pressure refrigerants like R-410A and R-32).
-
Better corrosion resistance, especially in coastal or industrial places.
