Parker R46-02CK Miniature Air Regulator 150 Psi 1/4 Npt

Product Description

The PARKER R46-02CK is a miniature compressed air regulator designed to maintain consistent downstream pressure in pneumatic systems. Part of the R46 series, this regulator accepts a maximum supply pressure of 150 psi and delivers an output range of 0 to 125 psi through a 1/4 inch NPT port. Its compact plastic housing measures 2.06 inches wide by 3.43 inches high, making it well-suited for installations where panel space or inline clearance is limited. Fluid type is rated for water in addition to compressed air. Licensed HVAC techs, industrial maintenance technicians, and plumbers working with pneumatic control circuits are the typical installers.

The R46-02CK is intended for use in light-duty pneumatic and compressed air distribution systems operating within a temperature range of 40 degrees F to 125 degrees F. Its miniature form factor fits inline or panel-mount configurations where a full-size regulator would not be practical. The 1/4 inch NPT connections are common in residential and light commercial pneumatic circuits, process control lines, and compressed air tool supply networks. No integral pressure gauge is included, though a 1/4 inch gauge port thread is available for field installation of an external gauge.

Key Features

• Maximum supply pressure of 150 psi suits standard shop air and compressed air systems
• Output pressure range of 0 to 125 psi provides broad adjustment capability
• 1/4 inch NPT end connections for easy inline installation
• Compact miniature body: 2.06 inches wide by 3.43 inches high
• 1/4 inch gauge port thread allows optional external gauge installation
• Plastic construction keeps unit weight low at 0.38 pounds

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic systems requiring a miniature 1/4 inch NPT compressed air regulator rated to 150 psi maximum supply pressure.

Installation Notes

Installation is typically performed by an instrumentation or mechanical technician. Isolate and bleed all upstream air pressure before installing or removing the regulator. Apply thread sealant appropriate for pneumatic service to NPT fittings and do not overtighten plastic-bodied components. Verify the downstream pressure setting before returning the system to service.
