Bottom mount vacuum/pressure gauges are often attached to monitor system or vessel pressure. Because gauge needle does not have a zero stop, a no-pressure reading can be +/- 1-2 PSI.
We recommend either a teflon tape or more permanent liquid to seal the gauge.

DETAILS
- -30hg to 150 PSI
- AISI 304 Stainless-Steel Casing
- AISI 316 Stainless-Steel Bottom Mount Connection
- 1/4" Male NPT Fitting
- 2.5" Face
- Shatter Resistent Acrylic Gauge Lens
- +/- 3-2-3% Accuracy
Notes & Installation Instructions
To return gauge to zero after shipping, equalize the pressure using the rubber glycerin cap. This cap can either be pushed to the side to break the seal temporarily and allow the gauge to take in air, or leak some glycerin to return to zero. Or you can snip the tip of the cap per the instruction on the sticker when it is permanently installed so it will maintain zero. Gauge zero will move up and down with the local atmospheric pressure, so if cap is left un-trimmed, zeroing may need to be done periodically. The stainless steel case is filled with glycerine to protect the internals against vibration and pulsation. This prevents needle chatter and it is normal for a bubble to be in the fluid.
Gauge accuracy is maintained only in a temperature range of -40 to 140°F (-40 to 60°C), any measurement made outside of this range cannot be guaranteed accurate and may lead to malfunction. Gauges that have a +/- 3-2-3% accuracy are categorized as ASME B40.100 Grade B, meaning that the lower and upper 1/4 of the scale has 3% accuracy and the middle 1/2 is 2% accurate.
