Insulated copper aluminum connection pipe for split air conditioners. Copper ends + aluminum middle with PE insulation. Cost-effective alternative to full copper. R410A/R32 compatible, 3-15m lengths.
Our Insulated Copper Aluminum Connection Pipe is a refrigerant piping solution for split AC units, heat pumps, and refrigeration systems. Copper ends + aluminum middle with pre-installed PE insulation. A cost-effective alternative to full copper pipes – same reliable performance, lower material cost. Pre-insulated design saves on-site labor and installation time.
