Wilkerson R18-03-F0G0B Compact Air Regulator 3/8 Npt 300 Psi

Product Description

The WILKERSON R18-03-F0G0B is a compact compressed air regulator designed to maintain consistent downstream pressure in pneumatic systems. Built from aluminum die cast, this Series 18 unit handles a maximum supply pressure of 300 psi and delivers up to 165 CFM of airflow through a 3/8 inch NPT port. A built-in relief function allows excess pressure to vent automatically, protecting downstream equipment. The included pressure gauge provides a direct visual readout of outlet pressure. This regulator is suited for use by industrial maintenance technicians, mechanical contractors, and automation professionals who need reliable pressure regulation in tight-space installations.

The R18-03-F0G0B fits inline compressed air distribution systems where space is limited and consistent pressure control is required. Its compact form factor makes it practical for panel-mounted assemblies and modular pneumatic circuits. The modular connection design supports integration into multi-component filter-regulator-lubricator setups. Typical applications include factory automation, production equipment, and compressed air tool supply lines where working pressure must be maintained within a defined range of 0 to 125 psi output.

Compatibility

Designed as an OEM-style replacement compact air regulator for 3/8 inch NPT compressed air systems. Compatible with modular pneumatic assemblies using Series 18 components.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems specialist. Depressurize the upstream air supply completely before removing or installing any inline regulator. Verify that all NPT threaded connections are sealed with appropriate thread sealant per applicable pneumatic system standards. Do not exceed the rated maximum supply pressure of 300 psi at the inlet port.
