0-300 Psi Glycerin Liquid Filled Pressure Gauge, 2.5" Dial Size, 1/4" NPT Lower Mount, Stainless Steel Case, for Air Gas Water Oil Hydraulic Pressure Test

I bought this to replace a broken pressure gauge on my Hayward swimming pool filter. I installed it using a T-fitting on the pressure gauge port to connect both this gauge and an electronic ADC sensor.The readings from this gauge match the electronic sensor exactly, so I trust that it’s accurate. The gauge itself feels well-built and of high quality. It was easy to install and is very easy to read.Great value and performance—five stars from me.

Seems to be well built and works perfectly for my application.

I bought this gauge to replace the pressure gauge on my Hayward sand filter. This gauge is professional level! The quality, feel, and accuracy is far superior to the cheap factory gauges that need frequent replacement (and for just $3 more). We will see how long this lasts, but it looks nice and functions great for the price.

Looks nice, I figured the stainless case would be better than a chromed steel case. Liquid filled is generally better than dry for reliability and longevity.But the bubble in the glycerin is rather large. So large that the upper part of the dial - in the 10-20 PSI range - isn't covered by the glycerin. I could live with that, the glycerin in the mechanism would still get me reliability. But once installed the inside of the glass (where there is the bubble and no glycerin) was covered with condensation, see photo. So it's not hard to read, see photo. And unfortunately this range (10-20 PSI) is the working range for a residential boiler.This is the second glycerin-filled gauge that has had the same problem. So I can't say if this one is unique or if all liquid-filled gauges have this issue. This range of gauge is typical for boiler systems, so one would expect that it would be OK with hot (but certainly not boiling) temperatures.

Stainless steel, beautiful and functional.

Looks great. Better material than the ones I usually buy. Haven’t installed it yet as I have been very busy.

Replacement for pool filter pressure gauge. No leaks. Seems to be of quality construction. Easy to read face of gauge.

Sturdy casing seems well-made and hasaccurate readings.
