Parker R119-02B Regulator

The Parker R119-02B Regulator is a heavy-duty, standard series pneumatic pressure regulator engineered for high-flow industrial air preparation. Designed with a robust zinc body and a balanced poppet design, this unit ensures quick response and accurate pressure regulation even during wide variations in flow. This 1/4" NPT compressed air regulator features a substantial 300 PSI maximum inlet pressure and a 0-60 PSI reduced pressure range, making it ideal for precision control in HVACR and pneumatic systems. It utilizes a 100 SCFM flow capacity to maintain consistent downstream pressure. As a direct crossover, the R119-02B is identical to 0497281, allowing for seamless integration into existing assemblies. The relieving diaphragm design and heavy-duty T-handle adjustment provide the durability required for demanding contractor environments. Whether you are managing primary shop air or localized equipment headers, this Parker Watts R119 series component delivers reliable, non-drifting performance for critical process applications.

• High Flow Performance: Delivers up to 100 SCFM, ensuring adequate air volume for high-demand pneumatic tools and HVAC actuators.
• Precision Pressure Control: The 0-60 PSI range is specifically tuned for applications requiring lower setpoints with high accuracy.
• Rugged Construction: Built with a die-cast zinc body and Buna-N seals for extended service life in harsh mechanical rooms.
• Balanced Poppet Design: Minimizes the effects of inlet pressure fluctuations to provide a stable, constant outlet pressure.
• Simplified Maintenance: Fully compatible with the RK119B repair kit, allowing for efficient field servicing without removing the body from the line.

What is the difference between R119-02B and model 0497281?
These are identical units. The 0497281 is an alternative part number often used in specific OEM inventories, but the technical specifications and physical dimensions are exactly the same as the Parker R119-02B.

Can this regulator be used with bottled gases like CO2 or Nitrogen?
No. This regulator is designed exclusively for compressed air systems. Connecting this unit to high-pressure bottled gas exceeds its 300 PSI primary pressure rating and may result in equipment failure.

Does this unit include a pressure gauge?
The R119-02B features two 1/4" NPT gauge ports for flexible installation, but the gauge is typically sold separately unless specified as a "G" suffix model (e.g., R119-02BG).
