Wilkerson R03-02-G00 Miniature Air Regulator 1/4 Npt

Product Description

The WILKERSON R03-02-G00 is a miniature compressed air regulator designed to maintain stable downstream pressure in pneumatic systems. Part of the R03 series, it accepts supply pressures up to 300 psi and regulates output across a range of 2 to 125 psi. Maximum airflow capacity is 15 CFM. The body is constructed from zinc for a balance of durability and compact weight. A built-in pressure gauge and relief function are included, making this unit a self-contained pressure management solution for technicians working on instrumentation, automation, and light industrial pneumatic circuits.

This regulator is suited for residential and light commercial pneumatic applications where space is limited and precise pressure control is required. The 1/4 inch NPT port size fits common compressed air line connections, and the 1/8 inch gauge port thread accommodates standard instrumentation fittings. Typical installation scenarios include pneumatic control panels, small actuator supply lines, and point-of-use pressure regulation on shop air systems. It handles compressed air service only and is rated for operating temperatures starting at 32 degrees F.

Key Features

• Miniature R03 series form factor for space-constrained installations
• 300 psi maximum supply pressure with 2 to 125 psi adjustable output range
• 15 CFM maximum airflow capacity
• Built-in pressure gauge included with 1/8 inch gauge port thread
• Integrated relief function for downstream pressure protection
• Zinc body construction for lightweight durability

Compatibility

Designed as an OEM-style replacement or direct-install miniature regulator for compressed air systems using 1/4 inch NPT connections and operating within the R03 series pressure and flow parameters.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician familiar with compressed air system safety practices. Depressurize and lock out the air supply before installing or servicing the regulator. Use thread sealant rated for compressed air service on all NPT connections and avoid over-tightening fittings into the zinc body. Verify downstream pressure with a calibrated gauge after startup to confirm the regulator is set within the required range.
