## Customer Reviews

### ⭐⭐⭐⭐⭐ As expected
*by C***T on May 19, 2025*

Works well. Used to pressure test black iron gas lines.

### ⭐⭐⭐⭐⭐ Well built
*by F***N on April 19, 2025*

Gauge and fittings are very well built. Already used it for a pressure test on a drain line. Held five pounds for 24 hours. Nice brass fitting. The 30 pound gauge is perfect for low pressure testing,much more exact than the usual 100 pound gauges

### ⭐ Seemed to work then broke
*by M***M on February 2, 2025*

I installed this on my black pipe and added 15 lbs of air. The system shows that It held the pressure after i checked in several days. I released the pressure slowly thru a valve down stream, then removed the guage to use on another line I needed to test. Unfortunately the guage now shows around 18 lbs even before I add air. I tried adding air and releasing it but it never goes below 18. I can't see where there is an adjustment...and of course the 30 day return window was 2 days ago...so it appears I'm stuck with this broken guage.
