Watts R119-08CG-M2 Pneumatic Pressure Regulator

The Watts FluidAir R119-08CG-M2 Pneumatic Pressure Regulator is a 1 in. NPT relieving regulator with female NPT threaded connections that provides accurate, stable downstream pressure control in compressed air systems. It delivers an adjustable outlet range of 0–125 PSI from a maximum inlet of 300 PSI, with a high-flow capacity up to 400 SCFM to support demanding equipment, and uses a heavy-duty T-handle for precise, fast setting changes. The unit features a zinc body, an aluminum spring cage, and a Buna-N diaphragm, and it includes a CG-configured gauge with two 1/4 in. NPT ports for monitoring pressure. Designed for inline installation in industrial air-prep networks, common applications include manufacturing facilities, automation systems, process equipment, pneumatic control panels, and OEM machinery, where it protects downstream valves, cylinders, and actuators from pressure fluctuations. Operating temperature range is 40°F to 120°F (4°C to 49°C) and it is intended for service with clean, dry compressed air in industrial environments. Brand: Watts FluidAir / Parker.
