I've got some heat shrink tubing for sale. It slips over SS air lines and shrinks flush when exposed to a heat source (like a heat gun or an electric burner). I got a whole bunch of this in bulk for my own guns, and now I'm trying to sell off the excess.
It's $3/foot or $10 for four feet shipped.
This is my first post here, but I've been on automags.org for about five years and have great feedback
