How I ran compressed air lines through my shop: what parts I used, my thinking process along the way. The result is wonderful.
It's important to note that air hoses come in different sizes, and you will need fittings that match the size hose you use. The hose I used was 3/8". All the threaded fittings were 1/4". The hose barbs were 1/4" male to 3/8" barb.
