Copper Line Set high quality: Not All Copper Is established Equal
The term “copper line set” sounds simple, but below’s the catch: copper purity and manufacturing benchmarks differ wildly. low-priced imports normally use recycled copper with impurities that weaken the tubing and enable it to be vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s produced to the highest HVAC sector normal for seamless copper tube. That interprets into:
-
better burst stress tolerance (crucial for contemporary high-strain refrigerants like R-410A and R-32).
-
much better corrosion resistance, specifically in coastal or industrial regions.
