John, My head isn't working it's usual lousy way this morning...

pps: Di you buy that, or build it? If you bought it; where do I need to go to get one? If you built it; are you planning on a production run? :shocked:
Bob,
I just assembled it from parts which can be found in most hardware stores except for the gauge. I ordered all the parts from McMaster Carr.
2pcs 6140A62 Locking Head Air Chuck, Angled, 1/4" Female NPT Connection 8.86 Each
1pc 8063K37 Brass Air Fill Valve, Straight, 1/4 NPT, 1-5/16" Overall Length 3.94 Each
1pc 50785K233 Medium-Pressure Brass Threaded Pipe Fitting, 1/4 Pipe Size, Cross 9.57 Each
2pcs 54075K18 Choose-A-Color Air and Water Hose, with Male X Male Fittings, 5' , 1/4" ID, 300 PSI, Blue 6.50 Each
1pc 4023K311 Brass-Case Dual-Scale Gauge, 3-1/2" Dial, 1/4 NPT Male Bottom, 0-30 PSI 29.65 Each
I would change the 90's to 45's and use this fitting instead of the ones I got from Homless Depot.
2pcs 50785K82 Med-Pressure Brass Threaded Pipe Fitting 1/4 Pipe Size, 45 Degree Female X Male Elbow 4.00 Each
Of course the gauge is optional and if you leave it off then you only need a Tee instead of the cross.
I doubt that I can build them for a price that people would pay... just add up what I spent for mine and then look at the
Chinlee one at Summit Racing for $73 plus shipping.
John
