Wilkerson R19-03-FA00B Air Regulator 3/8 Npt 300 Psi

Product Description

The WILKERSON R19-03-FA00B is a Common-P1 compressed air regulator designed to control downstream pressure in pneumatic systems. Built on the Series 19 platform with an aluminum die cast body, it accepts supply pressures up to 300 psi and delivers a regulated output range of 0 to 125 psi through a 3/8 inches NPT port. Maximum flow capacity is 64 CFM. The unit includes a built-in relief function and a 1/4 inches gauge port thread, making it compatible with modular manifold assemblies. Installation is performed by licensed pipefitters, pneumatic system technicians, or qualified maintenance mechanics.

This regulator is suited for use in industrial and commercial compressed air distribution systems where consistent downstream pressure is required. The modular connection feature allows it to integrate into filter-regulator-lubricator (FRL) assemblies or standalone pneumatic circuits. The Series 19 design is a common choice in manufacturing, MRO, and process environments where reliable pressure control of compressed air lines is a routine service requirement. No gauge is included, but the 1/4 inches gauge port allows field installation of a monitoring device if needed.

Key Features

• Common-P1 regulator type with 0 to 125 psi output range
• Handles maximum supply pressure of 300 psi
• 3/8 inches NPT end connections for standard compressed air piping
• 64 CFM maximum air flow capacity
• Built-in relief function for downstream pressure protection
• Modular connection support for FRL assembly integration
• Aluminum die cast body for durability and weight reduction

Compatibility

Designed as an OEM-style replacement or new-installation regulator for compressed air systems using 3/8 inches NPT porting and Series 19 modular pneumatic assemblies.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply completely before removing or installing any pressure regulator. Verify that upstream supply pressure does not exceed 300 psi and that all thread connections are sealed with appropriate thread sealant per applicable codes. Do not exceed the rated output pressure range during commissioning.
