2 in Liquid-Filled Pressure Gauge 0-400

This commercial pressure gauge measures from 0 to 400 psi and is built for technicians who need a reliable, vibration-resistant instrument. The 2 in nominal dial size provides clear readings in hydraulic, pneumatic and industrial maintenance tasks.

Accuracy and Environmental Limits

Accuracy follows a +/-3-2-3 percent pattern across the scale, meaning the middle third is tighter than the ends. The acrylic lens and 304 stainless steel case are not IP or NEMA rated, so the gauge should be shielded from direct wash-down or prolonged outdoor exposure.

Upgrade from Dry Gauges on Vibrating Systems

The liquid-filled case replaces dry gauges where pump pulsation or machinery vibration makes the needle unreadable. The jump is worth it when pointer flutter prevents a confident reading, but it does not add field-fill capability or a higher pressure range.

Questions about this item

Which pressure range should I select for a 0-400 psi system?

Choose the 0 to 400 psi range; it matches the gauge's primary pressure range exactly.

What does the +/-3-2-3 percent accuracy mean for my readings?

Readings are within 3 percent of full scale at the ends and 2 percent in the middle third of the 0-400 psi dial.

Will the 1/4 in NPT male connection fit my existing port?

Yes, if your port accepts a 1/4 inch NPT male thread; the gauge's process connection is that exact type and size.
