SKU CH-W8BM-49MR8

Measures pressure from 0 to 30 psi with a 2 in dial and 1/4 in NPT center-back connection

  • TypeElectronic
  • +/-3-2-3% accuracy ensures reliable readings
  • 304 stainless case resists corrosion in tough environments
  • 316 stainless sensor and socket handle aggressive media
  • 2 in dial with acrylic lens gives clear visibility
  • 1/4 in NPT center-back connection fits standard fittings

Application scope

This commercial pressure gauge measures from 0 to 30 psi and is intended for general-purpose monitoring on compatible equipment. Technicians and maintenance teams use it where a 2 in dial and 1/4 in NPT male connection fit the process requirements.

Installation check

Verify that the process port accepts a 1/4 in male NPT thread and that the center-back connection orientation suits the mounting location. The gauge is not panel-mountable and carries no IP or hazardous-location rating, so ensure the environment matches those limits. The 316 stainless steel sensor and socket contact the media directly.

Sustained operation

Accuracy follows a +/-3-2-3 percent specification across the scale, with 304 stainless steel case and acrylic lens providing the stated protection. California Proposition 65 notices apply because the product contains listed chemicals. No IP or NEMA rating is assigned for continuous exposure.

Questions about this item

What comes in the box with the Value Brand 4FMU7 pressure gauge and do I need to buy any fittings separately?

The gauge ships as a single unit with a 2 in dial, 1/4 in male NPT center-back connection, 304 stainless-steel case and acrylic lens. No extra fittings are included, so you will need compatible 1/4 in NPT pipe or hose fittings for installation.

The specs list accuracy as ±3-2-3 percent — which version should I choose for my application?

That single figure describes the gauge’s full-scale accuracy: ±3 % in the first and last quarters of the 0–30 psi range and ±2 % in the middle half. There are no alternative accuracy grades for this model, so select it if that tolerance meets your process requirements.

What does the 0 to 30 psi range mean when the gauge is installed on a live system?

The dial reads directly from 0 to 30 psi with the stated ±3-2-3 % accuracy across the span. The 316 stainless-steel sensor and socket handle the pressure media, while the IP/NEMA-not-rated case should be protected from wash-down or hazardous environments.
