Wilkerson R03-02-000 Miniature Air Regulator 1/4 Npt

Product Description

The WILKERSON R03-02-000 is a miniature compressed air regulator designed to control downstream pressure in pneumatic systems. Built on the R03 series platform, it accepts supply pressures up to 300 psi and delivers a regulated output range of 2 to 125 psi. Maximum flow capacity is 15 CFM. The body is zinc construction, keeping the unit lightweight at 0.3 pounds while maintaining durability in industrial and commercial service environments. A licensed technician or pneumatic systems specialist typically handles installation in compressed air distribution lines, process control panels, and automated equipment assemblies.

This regulator is suited for applications where space is limited and precise pressure control is required. The miniature form factor fits into tight panel or manifold installations. Port size is 1/4 inch NPT, with a 1/8 inch gauge port thread for optional downstream pressure monitoring. The unit handles compressed air service and includes a built-in relief function, allowing excess downstream pressure to vent when supply is cut. Fluid type is compressed air only.

Key Features

• Miniature regulator body fits space-constrained pneumatic installations
• 1/4 inch NPT end connections for standard compressed air line integration
• 300 psi maximum supply pressure with regulated output from 2 to 125 psi
• 15 CFM maximum air flow capacity
• Built-in relief function vents excess downstream pressure
• 1/8 inch gauge port thread for optional pressure gauge addition
• Zinc body construction for lightweight durability

Compatibility

Designed as an OEM-style replacement or direct-fit component for miniature compressed air regulator applications using 1/4 inch NPT porting in industrial pneumatic and process control systems.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or pipefitter familiar with compressed air distribution codes. Depressurize and lock out the air supply before removing or installing any regulator. Use thread sealant rated for compressed air service on all NPT connections and verify all fittings are leak-free before returning the system to pressure. Do not exceed the 300 psi maximum supply pressure rating.
