2-1/2" Pressure Gauge, Chrome Plated Steel Case, Dry, Compound Vacuum -30 Hg - 0-100 psi Lower Mount 1/4" NPT

I purchased this gauge to measure the pressure in an irrigation line. The line runs from a natural spring to my chicken coop and garden.The pressure in the line can not be greater than 9.5 PSI because the spring is only about 23 feet above the garden/coop.Before I installed the 0-30 psi gauge, it was reading 0 (ZERO).When installed, it gave a reading of 13... an impossible psi.When I removed the gauge, the needle went to the bottom of the gauge as in the picture. The gauge no longer reads any pressure.

I used this to make a pressure drop tester for small carburetors (trimmers, chainsaws, blowers). The most I pressurize to is approx. 10 psi. I like the versatility of also being able to use it as a vacuum gauge if needed. For my purpose this gauge works fine and it has a big enough dial so you can read what is actually going on. Good gauge for the money.

This dial has a 1/4” connection so I had to use an adapter. It has a great scale and is easy to read. I use it as a tire gauge.

easy to read; works as it should; and a fair price

Worked great

Works great for the money

Leaked from the gauge face out of the box.

The gauge did not work for measuring the water pressure in my irrigation system. I used a gauge from another manufacturer and it worked fine.
