MEANLIN MEASURE 0~300Psi Stainless Steel 1/4" NPT 2.5" FACE DIAL with Reset Pointer Liquid Filled Pressure Gauge WOG Water Oil Air, Lower Mount, with 1/8" x 1/4" NPT and 1/8" x 3/8" NPT Hex Bushing

With the red hand on it you can come back the next day and see what the highest pressure has been

A) glycerin filled B) Most similar gauges with red indicators display 180 degrees different, the gauge on the others needs to be upside down to read. C) goes to 300# D) What I really like is the stiffness of the highest pressure indicator, the similar gauges you can buy that screw onto a hose thread the red needle moves easily, they're really loose. This one stays where it's been pushed to.

MEANLIN MEASURE 0~100Psi Stainless Steel 1/4" NPT 2.5" FACE DIAL with Reset Pointer Liquid Filled.I purchased this particular gauge because it is liquid-filled and has "recording" ability.This gauge is for my water pump, so that I can "record" and set my high-pressure shutoff.The gauge comes packed inside a plastic bag, with 2 bushings and tape packed inside a nicely sized cardboard box.The gauge is pretty easy to read and has a black PSI range and a blue KPAx100 range.It might be nice if the psi numbers were slightly bigger, but they are pretty much the size that you see on many 2.5" gauges.The pressure pointer is black.The "recording" pointer is red.The main psi numbered indications are in 20 psi increments (0, 20, 40, 60, 80, 100), with 10 psi markers, and smaller 2 psi markers.On the gauge that I got, the "recording" needle "latch" is bent forward, causing the "recorded" pressure to be about 3 psi lower than the actual pressure present. Readings are repeatable.This does not affect the performance of the gauge, as long as you keep that 3-psi differential in mind.The "pointer/recorder" needle is pretty stiff to adjust, but it does adjust with some force.The liquid is intact, with no leaks.The NPT threads are cut smoothly, with nice sharp edges.Teflon tape and bushings are enclosed so that you can adjust the size from 1/4" NPT, to either 3/8" or 1/2" NPT threads, making it very handy to install this gauge in many applications.I don't know what kind of oil and glass was used, but it does leave some "distortions" along the outside of the gauge and the oil doesn't seem to flow smoothly without bubbles and some distortion.This does not really affect the ability to view the gauge readings much, just something to note.The oil may "settle out", after it has been installed and has time to "settle".Some of these comments may sound negative, but all in all, it does seem like a pretty decent gauge.

Product came with the psi needle on 25psi. Thought it would go to zero when using but it did not. It goes up in psi but it always goes back down to 25 psi instead of zero.

I bought this to track water pressure at our home. It's accurate within quoted specs (it's 2psi low at 100psi).I really like the hold pointer. It shows me the max pressure reached overnight.

I used this to replace the gauge on an air pressure device. I doubt my usage is what it's intended for.....but I installed it, made sure it had a good seal and it worked just fine, with no issues. I like having the reference needle. If it forget where I should be looking for pressure, I can see where I left the reference needle, for comparison.

This gauge is great for saving pressure settings for tools.I added this gauge to save the pressure setting for my paint gun so I don't have to fiddle around with it every time I go to use it.This makes it very convenient and saves me a lot of time.The stainless steel body keeps it from rusting and it looks great.They have the adapter fitting sizes listed incorrectly in the title.The adapter sizes that actually come with this are 1/4" to 3/8" and 1/4" to 1/2" NPT.

Good value. Unknown if can handle up to maximum pressures.I'm not sure if I'd want to test this at high pressures. if i do, i'm definitely not standing with my face directly over the top of the gauge while the pressure builds.i use this as a test gauge to carry around and fit to lines where i need a spot reading.good value. oil-filled. standard threads.
