omega air tank pressure gauge broke off the fitting

[JasonW]

My air tank dropped and broke of the oil filled pressure gauge. I ordered a new one but it has the wrong copper fitting, the 1/4 npt is too big. Does anyone know what size the fitting is on the pressure gauge itself that goes into the valve?

Thanks!

If it is smaller than the 1/4 NPT it will be 1/8 NPT. Technically, 1/8-27 NPT.

It may be metric

If it's a U.S. made or an Omega tank it's 1/8" NPT. If it's a Chinese brand tank it's M10*1 thread. Most 5000 psi gauges that have a 2" or larger dial have 1/4" NPT thread. Gauges that are 1.5" or smaller use 1/8" NPT threads.

Where did you find one? I haven't been able to find one at all.

Look at a dive shop, but hydraulic shop suppliers carry them also or talk to Air Venturi at Pyramyd air
