Review: Good replacement for nitrogen - Bought this to replace broken gaige on my nitrogen regulator (HVACR). Worked like a charm. So much nicer than stock gauge. However I should have paid attention to size closer. Its held up well...through workers knocking my tank over...:/
Review: Glycerin kept leaking out all over the place. - First, this is actually a 3/8” gauge and they include a 1/4” adapter. After install you have to cut the top rubber for the gauge to breathe, but glycerin can also leak out. In my case glycerin kept leaking out all over the place
