  • Copper air supply system

    I decided to add a 5-6 drop air copper air supply system to my shop. I went to Home Depot tonight and picked up 80' of 3/4" L copper for the main distribution and 50' of 1/2" L copper for the drops. Lots of elbows, couplers, 3/4" to 1/2" tees, 1/2" pipe to 1/2" NPT, lots of 3/4" unions, 1/2" unions, etc. I haven't decided on how many ball valves and drain legs yet.

    I'll post some pictures when I get started.

    Smart move. When you finish put a garden hose on it and flush it all out with water.

      So I take it they got all your remaining mad money! And, by the way last time I did it was a section at a time on the ground. Put it up one section at a time using shark bite fittings. Made a tough job easy. Wish I would have done the whole job with them, but at $4-6 each it would got ugly fast.......... Best of luck!

        Wish you'd held off a bit longer until you could see the installation I'm working on in my shop.

        I finally decided that I'd do all my air lines in glass. Yep, GLASS!

        Absolutely beautiful to look at.

        There are no stupid questions. But there are lots of stupid answers. This is the internet.

                      Once the glass pipe gets dirty inside it won't look so pretty.

                        Did you use the shark bite fittings as unions? That's what I bought the unions for to build in sections and connect together with union joints. Are the shark bite fittings for copper pipe or for some type of PEX like pipe? I'm planning on soldering all connections on the copper pipe.

                            Do they work on both M and L copper pipe?
