Value Brand 4CFU9 Pressure Gauge Liquid Filled 3-1/2 In

SKU CH-4647-H83MJ

A liquid-filled pressure gauge with a 304 stainless steel case measures up to 30 units and resists vibration through its liquid dampening system

  • Product typeElectronic
  • Liquid-filled design dampens vibration for stable readings
  • 304 stainless steel case resists corrosion in harsh environments
  • Center back NPT connection simplifies panel mounting
  • White dial with clear scale enables quick pressure checks
  • Accuracy within +/-3-2-3 percent supports reliable monitoring

3-1/2 Inch Liquid-Filled Pressure Gauge

This 3-1/2 inch liquid-filled pressure gauge measures pressure from 0 to 30. It suits technicians and operators who need a readable dial in vibrating environments. The liquid filling damps needle movement for steadier readings. It is built for general commercial pressure monitoring tasks.

304 Stainless Steel Case with Center Back Mount

The case and wetted parts use 304 stainless steel for corrosion resistance. A 1/4 inch male NPT connection at the center back allows direct panel or pipe mounting. The acrylic lens protects the white dial while keeping weight low. No field-fill option means the gauge stays sealed after installation.

Replaces Dry Gauges in High-Vibration Service

This unit replaces dry gauges where pulsation or vibration makes the pointer unreadable. The liquid-filled design extends service life in those conditions. It is not suited for applications requiring field refill capability or an IP-rated enclosure. The +/-3-2-3 percent accuracy fits general commercial specifications.

Questions about this item

What pressure range does the 30 psi gauge cover?

The gauge measures from 0 to 30 psi with an accuracy of ±3-2-3 percent across the scale.

What process connection does the centre-back mount require?

It uses a 1/4 inch male NPT thread that screws directly into a matching female port.

How should the liquid-filled gauge be oriented during installation?

Mount it with the centre-back connection pointing downward so the fill plug stays at the top and the glycerine dampens vibration correctly.
