Darley Fire Hydrant Pressure Gauge

The Darley Fire Hydrant Pressure Gauge is a mechanical gauge assembly designed to test static pressure in a fire hydrant or main. It connects directly to a 2-1/2" hydrant outlet and provides an instant pressure reading when the hydrant is turned on.

Features

• Instant Reading: Displays static pressure immediately when the hydrant is opened
• Gauge Size: 2-1/2" diameter gauge for clear visibility
• Pressure Options: Available in 100 PSI or 200 PSI ranges

Connection and Compatibility

• NST Compatibility: Made only for 2-1/2" NST connections
• Direct Installation: Screws on after removing the hydrant cap

Construction and Handling

• Bleed-Off Valve: Allows controlled pressure release
• Brass Cap: Chrome-plated brass cap for durability
• Rocker Lugs: Provide an easy grip when using a spanner wrench

How is it used

The gauge is installed by removing the hydrant cap and screwing the pressure gauge assembly onto the 2-1/2" outlet. Once the hydrant is turned on, the gauge instantly shows the static pressure. The bleed-off valve is used to release pressure as needed.

Who used it

This pressure gauge is used by personnel responsible for checking and verifying hydrant or main water pressure.

Maintenance information

The gauge assembly features a chrome-plated brass cap and mechanical components designed for repeated pressure testing applications.

Storage information

The compact gauge assembly can be stored with other hydrant testing tools when not in use.
