This is somewhat racing related (IMG:style_emoticons/default/smash.gif) I bought a new air pump for my old compressor but have to build a new manifold and re-plumb my air connections. Need some help. I'm using two lines, one is 1/2 steel and the other 1/4 copper. I'm using compression fittings on both. What tap size do I use on the 1/2" compression fitting to tap into my new manifold? On one side the compression fitting will be connected to the 1/2" pipe, the other side (minus the compression fitting) will be threaded into my new manifold. Both sides of the compression fitting are the same. Likewise for the 1/4" compression fitting, i.e., what tap size? Thanks. |

Ohjeeze.....plumbing 101
NPT= National Pipe Thread. Go to you hardware store. True Values are good for this.Grab a short piece of 1/2 in & 1/4 in threaded pipe. Find a reducer that fits each end......there's your check fixture, buy the reducer. Go to the tap section. Find a tap that fits each end.....buy those. Marked on the tap package will be a drill size for the hole to be tapped.....buy those. Go to a FLAPS. Find your required compression fitting that fits both ends of your check fixture *(your hardware store may have them)*. Take the check fixture back for a refund, ya cheepsumbitch. You're in biddness.
