At $10.01 per foot, it's the correct size for connecting compressor heads to tank fittings where the discharge circuit runs copper tubing. Copper is mandatory on the hot discharge side — compressor discharge air can reach 200-350°F, which eliminates nylon, rubber, and most plastic tubing as options for these connections.\u003c\/p\u003e\n\n\u003ch3\u003eWhere 1\/2\" Copper Tubing Is Used on Compressor Systems\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge tubes:\u003c\/strong\u003e The run between the compressor head outlet and the tank check valve.
