Well made gauge

Appears to be a well made gauge. I use it on a large air compressor. I can't speak to its durability as I've only had it a month, but I see no reason why it's going to fail any time soon.

Pros
  • Check, measure and inspect
Cons
  • Slightly torn

Good quality. Output 1/4 MNPT accurate.

1/4 MNPT gauge outlet odd size. It should be 1/4" but too big to fit in my 1/4 FNPT air filter. I'm going to re-tread with a 1/4" NPT die. Here I hope. Two stars. One for her, one for me. UPDATE: Air cleaner gauge intake turned out to be abnormally large. Probably a meth. So it was my fault that the 1/4 MNPT fitting didn't fit. This is a very good quality liquid filled pressure gauge at a very good price. So I changed my rating to 5 stars. Sorry for my mistake.

Pros
  • Gauge
Cons
