Pressure Gauge for General Purpose Testing

The Value Brand 4FLW1 is a general purpose dial pressure gauge designed for commercial test and measurement applications. It features an ABS plastic case and an acrylic lens with a nominal dial size of 2 1/2 inches. The gauge uses a bronze sensor and brass socket for durability.

Installation Notes and Common Issues

The gauge connects via a 1/4 inch male NPT process connection located at the bottom of the unit. It is not panel-mountable, so plan for inline or surface mounting only. Accuracy follows a +/-3-2-3 percent specification across the scale.

Pre-Order Compatibility Checks

Verify that your system uses a 1/4 inch female NPT fitting to match the gauge connection. Confirm the media is compatible with bronze sensor and brass socket materials. Note this product carries a California Proposition 65 warning for cancer and reproductive harm and is not rated for hazardous locations or IP/NEMA environments.

Questions about this item

How can I confirm the gauge is reading within its stated accuracy after installation?

Apply a known reference pressure and verify the needle stays within the +/-3-2-3 percent accuracy band across the dial.

What comes in the box and what extra fittings might I need?

The gauge itself is supplied; you may need a 1/4 inch NPT male adapter or sealant if your process connection differs.

Which dial size should I choose for a panel that only fits a 2-1/2 inch face?

This model has a 2-1/2 inch nominal dial, so it matches that cut-out exactly.
