Cascade Stem-Mounted Fire Apparatus Gauges
Cascade Stem-Mounted Fire Apparatus Gauges provide dependable pressure and vacuum readings for fire pump and apparatus applications. Their liquid-filled construction helps dampen pointer movement caused by vibration while providing clear, stable readings in demanding fire-service environments.
Available in 2-1/2 in. and 3-1/2 in. dial sizes, these gauges are offered in pressure, compound, and vacuum configurations for monitoring discharge pressure, intake conditions, and drafting operations.
