Why does my compressor line get hot? - About Air Compressors…
18/1/2019· My air compressor has a copper line on it and after it had been running for a long period of time the copper line was very hot – melted my rubber air hose. Interesting question, Mr. Griffeth. I am working on the assumption, since you do not say so, that the copper line you refer to is the one running between the compressor pump head and into the compressor receiver?
