Pro-source NR200-02N Miniature Air Regulator 170 Psi 1/4 Npt

Product Description

The PRO-SOURCE NR200-02N is a miniature compressed air regulator designed to control downstream air pressure in pneumatic systems. Built from aluminum, it accepts a 1/4 inch NPT port connection and handles a maximum supply pressure of 170 psi. The regulated output range spans 2 to 120 psi, making it well-suited for applications that require precise low-to-mid range pressure control. At 53 CFM flow capacity, it supports moderate pneumatic demand without creating a bottleneck in the supply line. The unit includes a built-in relief function to vent excess downstream pressure when the set point is exceeded. Its compact footprint makes it appropriate for installations where panel or manifold space is limited.

This regulator is intended for use with compressed air systems in industrial, maintenance, and light manufacturing environments. Its miniature form factor suits inline mounting on pneumatic tool feeds, small automation assemblies, and equipment panels. The 1/8 inch gauge port thread allows a pressure gauge to be added at installation if monitoring is required. Licensed trades and industrial maintenance technicians typically specify this type of regulator where space constraints or modular pneumatic circuit designs call for a reduced-size component.

Key Features

• Miniature regulator body sized at 2.87 inches tall and 1.57 inches wide by 1.57 inches deep
• 1/4 inch NPT port size for standard compressed air line connections
• Regulated pressure range of 2 to 120 psi with 170 psi maximum supply pressure
• 53 CFM airflow capacity for moderate pneumatic circuit demand
• Integrated relief function vents excess downstream pressure automatically
• 1/8 inch gauge port thread included for optional pressure gauge installation
• Aluminum body construction for lightweight, corrosion-resistant service

Compatibility

Designed for use with compressed air systems requiring a miniature inline regulator with a 1/4 inch NPT port and a maximum supply pressure up to 170 psi.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the air supply line completely before removing any existing regulator or installing this unit. Verify that upstream supply pressure does not exceed 170 psi and that the operating temperature remains within the rated minimum of 14 degrees F. Apply appropriate thread sealant to NPT connections per standard practice and confirm there are no leaks at all joints before returning the system to service.
