Review: Great Build Quality - Nice quality gauge with an easy to read dial and hefty weight. Nice that they included the 1/8NPT adapter.
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...:/
