4" (101.6 mm) Steel Air/Water Pressure Gauge is a durable, UL-listed and FM-approved gauge for pressurized air and water-based systems, including fire sprinkler systems. The 1/4” (6.35 mm) male National Pipe Thread (NPT) pressure connection threads quickly to a pitot tube, fire hydrant test cap, or trim kit to measure air and water pressure between 0 PSI and 300 PSI.
Each 4" (101.6 mm) Steel Air/Water Pressure Gauge is designed for use in ambient temperatures of -40F to 140F (-40C to 60C). Displays pressure readings accurate to +/-3/2/3% of span in accordance with NFPA 25.
This 4" (101.6 mm) Steel Air/Water Pressure Gauge is made with a painted black steel back and corrosion-resistant copper alloy components. This gauge is suitable for use with any substance that will not obstruct the pressure system or attack copper alloy parts.
