SENCTRL 0-200 Psi Glycerin Liquid Filled Pressure Gauge, 2.5" Dial Size, 1/4" NPT Back Mount, Stainless Steel Case, for Water Oil Pressure Test in Pipe Pool Pump Sand Filter Air Compressor

These gauges are so economical that I installed a gauge on either side of a new Big Blue water filter on my water line coming into my home. The Big Blue replacement filters cost about $25 each and the only way you can tell if they need to be replaced is when you notice a drop in water pressure in your home indicating that the filter is full. That's kind of a hit or miss way to monitor them. By using these gauges, I can see when the psi on the gauge after the filter is approaching 10 psi lower than the psi going into the filter and I will know it is time to change the filter cartridge. Over the years this will save a lot of money and keep the water pressure up to where it should be.

Works great thinks

I own a bunch of corny kegs that need to stay charged (under 30 psi) for my application. I have another gauge from Harbor F that was my initial one to verify pressure in my system. So this one is the newer one I added and it performed on par with other gauge at this price point. One thing that I thought was odd...the instructions tell you to open the little rubber cover at the top to level off the pressure inside it but trying to put the rubber cover back on snipped a piece of the rubber off as I tried fastening it back on. I thought the liquid integrity would be compromised but it held and didn't leak. I like this one enough, I'm going to try and get a few more. Recommended item!

Good quality good price. Works as it should.I reccomend thus gauge.

Nicely built and easy to read.
