I started working on the air line plumbing for the new shop. Everything is going well, except I can't figure out how to get this one valve connected without leakage. I'm using 1/2" galvanized pipe, surface-mounted with UnitStrut. My initial plan is to have 3 outlet 'stations' with 3/8" and 1/4" outlets at each station. I'm also considering running an overhead line for a drop reel, but I haven't decided if that's really necessary yet.
The pipe goes underground for almost 20', which will cool the air nicely. I have a water trap and then a filter first thing for when the air gets into the garage. Once all the pipes are set, I'll adjust everything so it slopes back towards the compressor.
I'm having a problem getting the valve both tight and clocked correctly, which I'll probably have to solve by using a longer nipple so the valve doesn't bottom out on the elbow.
Any pointers would be appreciated!
