MEASUREMAN 2-1/2 Dial Size, Glycerin Filled Pressure Gauge, 0-100psi/kpa, 304 Stainless Steel Case, 1/4NPT Lower Mount

Used this gauge for fuel injection tests on a direct-injected marine outboard motor. The fluid-filled gauge was able to dampen the pressure fluctuations in the fuel and air headers that come with this type of fuel injection system (pressure control valves and injectors opening and closing). However, no paperwork came with the valves indicating the overall accuracy. A bench pressure test of the gauge against calibrated gauges showed the inaccuracy to be greater than 5% of full scale. I expected better. I had to produce an indication bias curve for each gauge purchased to ensure an accurate result.

Product leaked oil right out of the box. Top of the gauge has a plastic plug intended to contain the oil. If mounted straight vertical this gauge may work for you. Any other orientation or for an automotive application this gauge is useless.

A replacement for me,about a month ago I hooked it up. No problem so far, it looks great, and much easier to see than my old one. Really nice for the money.

test hyd pressure of tractor works great

I bought this gauge to replace a 14-year-old gauge on my well pump that had stopped working. This gauge appears to be well-built and I like that it is oil-filled. Just dont forget to remove and re-install the oil plug before putting the gauge into service to allow the internal pressure to normalize. I also installed a new pressure switch at the same time and when I turned the pump on the gauge went right up to 50 psi and the pump shut down as expected. I only gave it 4 stars for accuracy and value because I havent had it long enough to make a full assessment of these qualities. I hope this gauge lasts as long as the old one, but time will tell.

Arrived quickly and performed as expected. Using it to monitor the pressure of the plumbing in our camper, which uses an old SHURflo pump to which I added the accumulators shown in the picture, which greatly reduce the # of times the pump cycles on and off when the faucet valve is not open most of the way. Now that I have the pressure gauge, I can see whether the pump is working properly and what the on/off pressures are (the latter one being settable to some degree). I chose an oil-filled gauge to insure a smooth reading that does not jitter due to the pulses from the pump.

none

I used it to test a pressure pump that ranges from 0-10psi. It stuck the second time I used it.

Be sure this is what you want. The fitting won’t fit on your faucet, it’s 1/4” male. Wasted money for me but it might be a good gauge.

Received item broken and package opened liquid was all over the bubble wrap and smelled of a strong chemical or odor.
