Norgren 11-002-037 Air Pressure Regulator 3/8 Npt 400 Psi

Product Description

The NORGREN 11-002-037 is a compressed air pressure regulator designed for industrial and commercial pneumatic systems. Built in the Norgren Series 11 line, this regulator controls downstream air pressure up to 400 psi, protecting equipment and maintaining consistent system performance. It accepts a maximum air flow of 120 SCFM and handles temperatures up to 175 degrees F. The 3/8 inch PTF port connections and modular body design make it suitable for inline installation in compressed air distribution networks. A built-in pressure gauge and integrated relief function are included, reducing the need for additional fittings or separate relief valves.

This regulator fits residential, commercial, and light industrial pneumatic applications where reliable pressure regulation of compressed air is required. The modular connection design allows it to be combined with other Series 11 components such as filters and lubricators to form a filter-regulator-lubricator assembly. It is commonly installed at point-of-use drops, compressor outlets, or tool supply lines where stable downstream pressure is critical. Licensed industrial mechanics and experienced tradespeople handling compressed air systems are the typical installers.

Key Features

• Handles maximum working pressure of 400 psi for demanding compressed air systems
• 3/8 inch PTF port size with 1/8 inch gauge port thread for flexible plumbing configurations
• Integrated pressure gauge included — no separate gauge required
• Built-in relief function vents excess pressure to protect downstream equipment
• Modular connection design compatible with Series 11 filter and lubricator units
• Rated for air temperatures up to 175 degrees F

Compatibility

Designed for use with compressed air systems requiring 3/8 inch PTF port connections. Compatible with Norgren Series 11 modular pneumatic components for filter-regulator-lubricator assembly configurations.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician familiar with compressed air distribution. Always depressurize and lock out the air supply before installing or servicing this regulator. Ensure flow direction aligns with the inlet and outlet markings on the regulator body. Verify that all downstream components are rated for the working pressures applied through this unit.
