One of my neighbors was asking me how to delete the AC system from his late 1960's GM sedan and it had those style claps on the AC lines. I was confused when I saw them because they were not the crimped-on style that I am used to. Until I saw this, I thought someone used PEX clamps to home-make the AC hoses.
