Watts R119-04C General Purpose Pneumatic Regulator

The Watts R119-04C General Purpose Air Regulator delivers precise 2–125 PSIG downstream pressure for industrial compressed-air systems, with a 1/2 in NPT inlet and two 1/4 in NPT gauge ports for monitoring. As a relieving, diaphragm-operated regulator in the R119 series, it uses a spring-loaded T-handle to set pressure and features a zinc body with a brass bottom plug and an aluminum spring cage, designed for inline or panel mounting in industrial environments. Capable of withstanding up to 300 PSIG maximum inlet pressure and delivering up to 150 SCFM, it operates across 40°F to 120°F and suits manufacturing equipment, pneumatic tools, assembly lines, and packaging machinery where stable outlet pressure and high airflow are required. Optional GC230 gauge compatibility and common replacements Watts R119-04CG, Watts R119-03C, or Parker R119-04CG are available.
