How much pressure is in a water fire extinguisher? 100 psi is the green charged zone and the dial range goes from 0 to 200 psi (0 to 1380 kPa). The male thread is 1/8" NPT (outside diameter ~3/8") and the gauge diameter is 1-5/8" (41 mm). These gauges work with water, AFFF foam and loaded stream handheld extinguishers.

How Much Water Pressure Is Required for a Fire Sprinkler …
Without minimum water pressure and flow, fire sprinklers cannot work as intended. They won’t be able to put out enough water to suppress fires. If the pressure at a sprinkler head is below a bare minimum of 7 psi , the water won’t be able to push out the sprinkler cap when the heat-sensitive bulb breaks.
An extinguisher designed for use with a dry chemical only (ABC powder) like the one on the left in the figure is pressurized to 195 psi (1,344 kPa). Its gauge is in the green zone indicating that it is ready use. The clockwise red zone indicates an overcharged situation that could measure as much as 400 psi (2,758 kPa).
