Air Jade Insulated Copper Aluminum Pipes Line Set for Ductless Mini Split Air Conditioning,Heat Pump System,1/4"&1/2" OD (25' Length)

Definitely not 100% copper like advertised. The ends and connections are copper but about 4 inches into the line it’s aluminum with a copper colored plastic cover. Very frustrating because I needed this ASAP and now I have to order another one.
