Review on CARBO Instruments Pressure Connection Assembly by Hector Smith

The first thing I did before using the tester was to make sure the meter itself could hold air pressure for 24 hours. I fitted one end with a 1" to 3/4" adapter and installed a 3/4" male into the adapter. I then added 15 pounds of air pressure. The pressure gauge showed good results and passed the test. I would recommend this one Recommend pressure gauges to anyone who needs a reliable tester for finding leaks in gas lines or for any project that requires a 15 pound tester.
