Air conditioning and refrigeration (ACR) copper tube is a seamless, round copper tube specifically manufactured for refrigerant circuits in HVAC/R systems. The material is Phosphorus-Deoxidized High Residual Phosphorus (DHP) copper — designated as TP2 in Chinese standards and Cu-DHP / UNS C12200 internationally — which provides excellent brazeability, formability, and resistance to hydrogen embrittlement that would otherwise occur in oxygen-bearing copper during brazing
