Copper Line established high quality: Not All Copper Is developed equivalent
The term “copper line set” Appears clear-cut, but right here’s the catch: copper purity and producing requirements differ wildly. low-cost imports normally use recycled copper with impurities that weaken the tubing and ensure it is susceptible to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s created to the highest HVAC field conventional for seamless copper tube. That interprets into:
-
better burst stress tolerance (crucial for contemporary superior-pressure refrigerants like R-410A and R-32).
