evap coil box leak, liquid nails to seal it?

thahalibutJuly 9, 2011

Had to fix a plugged drain pipe & found some leaks.

Where the copper tube goes in the box its leaking small amount of cold air. The tube is warm when running, what should I use to seal that properly with a cold box & warm tube? I was going to use clear liquid nails.

Also what should I use to further insulate the top tube thats wrapped in sticky tar stuff the first 18" from the box. The rest of it is wrapped in normal pipe insulation, this gets very cold.

They make a hvac putty that would work good for the small copper line. Sometimes you can find it in the electrical section at the big box stores.. Some call it perma gum..

I would use pipe insulation on the other line...
