Has anyone here tried this digital gauge from Aliexpress? Or perhaps one like it at a similar price? (Under $70)
Available in a wide range of thread sizes and pressure ratings. I am thinking the best option is the 40 MPA (5800 PSI) including 1/4 NPT and 1/8 NPT. They also list G 1/2 and G1/4 which would be G standard straight threads, but I am guessing NPT T fittings are going to be easier to find. I would imagine you would need to be more careful in handling the assembly with 1/8 NPT fittings so as to not damage them with such a large gauge attached at 90 degrees.
My plan is to have an inline, quick connect gauge on a T fitting with QD connectors on both ends, that I can use with my main compressor setup when filling tanks and guns so I have a more accurate pressure indication, but also for "calibrating" all the gauges I have on various guns and compressors. By calibrating I am talking about hooking the gun to a pressure source with the digital gauge between the two, then putting color coded paint marks at the max pressure point on the dial for each gun and marks at the most used pressures on the fill station and compressor gauges, such as 200, 250, 300 and 310 bar. None of the gauges on my guns, tanks or compressors read the same. Some are WAY off, usually in the lower pressure direction than most of the others. All but one of them which I will be replacing, give a consistent reading, just off from every other gauge.
Also looking for a source for a couple of stainless steel high pressure (6000 psi working pressure is preferred) T fittings and step up or down threaded adapters that aren't priced like they are made from gold if anyone has any suggestions.
