Copper Line Set high quality: Not All Copper Is produced Equal
The phrase “copper line established” Appears clear-cut, but in this article’s the catch: copper purity and manufacturing specifications vary wildly. low cost imports generally use recycled copper with impurities that weaken the tubing and enable it to be liable to pinhole leaks.
Our copper is ASTM B280 compliant, meaning it’s produced to the highest HVAC sector typical for seamless copper tube. That interprets into:
-
greater burst pressure tolerance (significant for modern large-strain refrigerants like R-410A and R-32).
-
Better corrosion resistance, specifically in coastal or industrial parts.
