Watts R119-03C Air Reg

The Watts R119-03C is a professional-grade 3/8-inch pneumatic pressure regulator designed for high-demand industrial air service. This unit is the direct replacement for AL-487, offering a seamless crossover for technicians maintaining legacy systems. Engineered with a rugged zinc body and an aluminum spring cage, the R119-03C utilizes a diaphragm-operated balanced poppet design to ensure quick response and precise regulation, even during wide variations in flow. With a maximum supply pressure of 300 PSIG and a reduced pressure range of 2 to 125 PSIG, this relieving type regulator is ideal for installations requiring consistent downstream air pressure. The heavy-duty T-handle adjustment allows for easy field calibration, while the 110 SCFM flow capacity ensures your pneumatic tools and cylinders receive the volume required for peak performance. Featuring dual 1/4-inch NPT gauge ports, this standard air regulator provides versatile monitoring options for any contractor's setup.

• Precise Pressure Control: The balanced poppet design minimizes the effect of inlet pressure fluctuations on the set downstream pressure.
• High Flow Efficiency: Rated at 110 SCFM to support high-consumption pneumatic equipment without significant pressure drop.
• Durable Construction: Features a robust zinc body and Buna-N diaphragm for long-term reliability in harsh HVACR and industrial environments.
• System Protection: The relieving design allows for the venting of excess downstream pressure, protecting sensitive components.
• Installation Versatility: Direct 3/8" NPT ports and dual gauge tappings allow for convenient mounting in various configurations.

Is the Watts R119-03C compatible with water or oil service?
No, this regulator is specifically engineered for air service only. Using it with other media may damage the internal Buna-N seals.

Does this unit include a pressure gauge?
This model features two 1/4-inch NPT gauge ports, but the gauge itself is sold separately. We recommend using a standard GC230 gauge for accurate monitoring.

Can I use this to replace an older AL-487 regulator?
Yes, the R119-03C is the manufacturer-designated direct replacement for the AL-487 model, maintaining the same form and function for industrial applications.
