Watts R15-00C Pneumatic Air Pressure Regulator

The Watts FluidAir R15-00C Pneumatic Air Pressure Regulator is a compact 1/4 in NPT relieving regulator that automatically reduces incoming air pressure to a preset downstream level for reliable, stable control in compressed air systems. Built with a zinc die-cast body, it offers an adjustable outlet pressure via a control knob and dual gauge ports for monitoring inlet and outlet pressures, supporting up to 250 PSI maximum inlet pressure and inline or panel mounting. Designed for pneumatic automation, assembly lines, air-operated tools, process control panels, and OEM equipment, it helps protect downstream components and extend the life of valves, cylinders, and actuators by maintaining consistent downstream pressure. Common replacements include Watts FluidAir R10-02C, R119-02C, and R119-03C.
