[Shop-talk] Looking to buy a compressor

[old dirtbeard]

Hi Darrell,

Copper tubing with compression fittings should be fine. It will work
harden, but it should not break. The air gets hot enough to melt solder (I
had that happen).

You do not need a water trap or drain here, the water will be vaporized and
end up in the tank.

Also, you will want to isolate the cooler from the fan guard if the guard
is plastic, of course.

best,

doug
