You will probably want to buy some push to connect fittings at some point, you can get the from McMaster-Carr (

They are brass fittings that allow you to connect the pneumatic tubing to things such as, the compressor, regulators, tanks, pistons, and all your other brass fittings etc. And don't forget to use pipe thread tape on all your fittings, my team didn't use it our rookie year and our entire system leaked.
Hope this helped.
