PIC Gauges 202L-158F Center Back Mount Glycerine Filled Pressure Gauge w/ SS Case/Bezel, Brass Internals, PC Lens, 1.5" Dial, 0/160 psi Range, 1/8" Male NPT

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.

This gauge is helpful because it mounts from the back of the case instead of the case's side. If space is a problem, this can be a useful feature. It was fully glycerin filled and the plug was intact. Used as a test gauge (temporarily installed, not permanent) to measure the suction side of residential pool equipment via the pump's threaded test port. Works as advertised.

Seems very accurate. Very good quality case and lens, I love the stainless and real glass. Guts and needle move steadily.-UPDATE: After a just a couple months in my toolbox and very light/infrequent use I noticed that every radiator cap I tested with it was failing the test, even new caps. Checked it against my old gauge and there was a four psi difference. That's a rather large difference on a 15 psi test. Maybe it was something I did; so I came here to buy another but it more than doubled in price, no thanks.

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.

I bought this gague just be where what happend to me .after installing the gague I noticed it was now sitting own 5hg and would not return to 0 it's very easy to bend while using a wrench .

Fantastic buy. Have had others no better but at twice to three times the cost. Unless it fails quickly in use, an excellent gauge. Also arrived in two days as expected with Prime.

I love this guage. It's much easier to read then the stock Ninja bottle guage. It was easy to install.

Good quality gauge, good value, good construction.

My car will look cooler. Dont know if it showed face down or 360° from the valvestem piston seal ;)
