Yong Heng Gauge Position

[Chopper61]

Hey all, I am mechanical inclined I work on outboards and a diy guy. I’m new to these little powerful compressors. I’m short physically, my compressor is on a bench in my shop it’s hard for me to accurately set and see the gauge I would rather not standing directly over this machine. So I want to reposition the gauge I ordered a 4” nipple and a female to female elbow so I can just stand back and watch it it’ll be a lot easier for me to keep an eye on it. Does this reposition effect the schematics of the compressor? again it’s a Yong Heng thank you

Another option would be to replace the center back gauge with a lower mount gauge so it faces you. It would eliminate the extra fittings and potential leak points. I buy a lot of gauges from directmaterial.com. Check out their PB158L-KO5 0-5000 psi gauge for $8.52. You'll need a 1.5" gauge because anything larger will require a reduction adapter since they will be 1/4 NPT threaded instead of 1/8 NPT.

I am going to benefit from this question and answer thread.I too have the same aversion to standing over the top of the compressor.Easy solution.Thanks Humdinger!

The factory gauges are almost certain to fail. I'd recommend getting an oil filled gauge to replace it with. As for affecting schematics, that is a negative.

Great information I hate it when I have brain farts though! lol good grief I know that working on vaccine and fuel pressure gauges! I thought it would be different b/c of the high psi! Already ordered I’ll post a pic after install. Hopefully lol depending on if I’m here or not. Lol thanks to you both!

I am usually filling my 9L fireman tanks (I have two older and one newer tank) to a max when the auto shot-of turns it OFF about 4200ish psi, but I am trying to be extra careful.

I have an external Temp measuring unit and me myself monitoring not to exceed 55C neither on a compressor head also cylinder head, also I have an inline extra Huma digital gauge to monitor the line air pressure.

If I could weigh in. Can’t stand the quality control on these compressor temp probe. What I did was take a very small bit of epoxy right to the body on the inside. Coat the probe with grease actually I used thermal paste it’s very slippery. Stuck it in then pulled it out it made a cavity. Then when dried I simply put the probe back in. What you have to remember is high heat epoxy holds heat, so it takes longer to register however when u turn the compressor back on, it won’t register going higher till the temp exceeded the reading. I have found no rise in heat for 3-4 minutes no need to worry, just means it’s lower than temp it’s registered

Btw yes in installing a gauge to the pmv so yes good suggestions thanks again

 

[Chopper61]

Yeah got it n done thanks

Please keep in mind that if you are going to use an NPT threaded gauge you will need a metric to NPT bushing as the compressor threads are metric. I replaced my faulty stock gauge two years ago with a larger bottom entry gauge that is glycerin filled and easier to read.

Following this. I would love to put a better guage on my Yong Heng. That is my only gripe with it so far.
