Stainless Pressure Gauge 150 PSI with fitting

Ordered several of these for my Reverse Osmosis maple syrup setup and they work fine. No leaks, pressure seems accurate.UPDATE: The gauges are 3 years old and I had my first problem - the rubber plug came out of the back. I am running my pump at 140PSI this year and it induced a vibration on the lines throughout the RO setup. I noticed there was liquid coming from the gauge, but could not see where as they were mounted to the board. I unconnected the gauge and saw the plug was out. If that was the problem or something else, I do not know, but it lasted three years.UPDATE 2: It has been 5 years and a second gauge stopped working. I figure something must have clogged it. I changed it out with a DIGITEN Water Pressure Gauge 2" size and will look in detail to see if I can find the problem.

Bought two gauges for a RO system. One for pressure into the system and the other to give pressure after the first three filters. After a period of time, the pressure difference of the two gauges would show deterioration in the filters. Pressure in gauge showed 74 PSi. The second gauge showed 84 PSI?? Swapped position of the two gauges and sure enough, the error of 10 PSI followed the gauges. That's a lot! I guess I will be looking around for much better gauges from someone else.

works as designed

good
