The time period “copper line set” Seems simple, but below’s the catch: copper purity and production requirements change wildly. low-cost imports generally use recycled copper with impurities that weaken the tubing and make it liable to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s manufactured to the best HVAC marketplace regular for seamless copper tube. That interprets into:
-
larger burst stress tolerance (significant for contemporary substantial-strain refrigerants like R-410A and R-32).
-
