PIC Gauges 202L-158R Center Back Mount Glycerine Filled Pressure Gauge w/ SS Case/Bezel, Brass Internals, PC Lens, 1.5" Dial, 0/5000 psi Range, 1/8" Male NPT

I like the stainless steel case and the liquid (glycerin?) fill. I also like the small size.

Got this gauge to replace one on regulator for argon tank for TIG welder. Noticed original gauge showed zero when still 400-500 PSI left in tank. This one seems more accurate. Quality seems good. Gave only 4 stars due to rather large bubble which does kind of impair vision of gauge. I rotated gauge so bottom on top so most of reading scale is submerged. This does not bother me too much as long as gauge reads accurately

fast shipping, good price, will use again for other pressures

This is a review of the 0 to 30 in Hg vacuum gauge. I thought this might be a handy thing to have installed under the hood, as I happened to have a 1/8 NPT port on the carburetor base that was not being used. Unfortunately, it was not really useful because as the engine warmed up, the indicated idle vacuum increased as well. When it got to a completely unrealistic level for this engine and cam, I shut down the engine and removed the gauge. Shut down (with obviously zero vacuum in the manifold) but still warm, the gauge read 12 in Hg. Then, as the gauge cooled off on the work bench, the needle went back to zero. So, I would not recommend this for under hood use.

For the money, it's not bad, but perhaps if you JUST WANT IT TO WORK, then spend a little more for a better one. Keep in mind, more expensive doesn't always mean better.Mine came statically at 15hg, but that may be expected. I build a vacuum pump by turning an old air compressor backwards, and the gauge I had on hand was a dry gauge. When it was new, it worked fairly well, but now that it's aged a bit, I have to tap the gauge to get a "current" reading which is really annoying. When the pump is turned off, sometimes it's stuck at some level so I never know what my vacuum pressure is, so I had to replace it with something better, oil filled. So, this gauge is WAY better than what it replaced.So, as described above, I no longer have to constantly tap the gauge to get a reading, which I'm happy with. However, when I turned on my pump with this new gauge for the first time, it started moving slow, which is expected, since the tank is a 30 gallon tank. Once it started dropping pressure, it started dropping fast. However, it seems this gauge is a little "sticky". It "pulse drops" by about 3-5hg at a time, but it isn't stuck.I also, I question the accuracy of this gauge. When I originally built my pump, I was able to pull about 28-30hg (based on the dry gauge I installed). Now, the same gauge only goes as low as 25hg. Now, only changing the gauge from a tired dry gauge to this new wet gauge, I'm able to easily reach 30hg, and even peg the needle in the max position, which I could imagine 35hg (which isn't possible).So, I might trust the accuracy of my old dry gauge, since it's easier to reach 25hg than to reach 30hg+. However, I'm just happy that I don't have to babysit the gauge while I'm using it.

1 of the 2 I ordered is very low on fluid inside the gauge. Would love if you could send me a new one and I can return defective gauge. I would happily update my review.

Bought this for a project that needed a small gauge and this has been working like a champ.

Very easy to use and install. I love the price. I'm using for a carpet cleaning extractor. Comparable product is $50. The readout doesn't match what I would expect. I suspect if I add 2 inHg to the readout the numbers make more sense. Provided for the offset adjustment, this gauge is a very useful tool.
