Parker PR364-02CSS Air Regulator 1/4 Npt 300 Psi

Product Description

The PARKER PR364-02CSS is a miniature compressed air pressure regulator built for demanding pneumatic applications where precise downstream pressure control is required. Part of the PR364 series, this regulator features a stainless steel construction and handles a maximum supply pressure of 300 psi with an output range of 0 to 125 psi. It flows up to 12 CFM and connects via 1/4 inch NPT end connections. A built-in relief function vents excess downstream pressure when the set point is reduced, making it suitable for systems that require safe pressure bleed-off. Licensed trades and industrial maintenance technicians install this component in compressed air distribution and point-of-use pneumatic circuits.

The PR364-02CSS is suited for light industrial, instrumentation, and process pneumatic systems where a compact footprint is necessary. Its miniature form factor makes it a practical choice for panel-mounted assemblies, machine tool air circuits, and tight-space installations. The stainless steel body holds up in environments with moisture exposure or mild chemical contact. The 1/4 inch NPT porting is a standard size across a wide range of pneumatic fittings and manifolds, simplifying integration into existing compressed air systems.

Key Features

• Miniature PR364 series design suited for compact pneumatic installations
• Maximum supply pressure of 300 psi with a 0 to 125 psi adjustable output range
• 12 CFM maximum air flow capacity
• Stainless steel body for corrosion resistance in wet or mildly aggressive environments
• Built-in relief function for safe downstream pressure venting
• 1/4 inch NPT end connections compatible with standard pneumatic fittings

Compatibility

Designed as an OEM-style replacement or direct-fit component for miniature compressed air regulator applications using 1/4 inch NPT connections and requiring a maximum supply pressure of 300 psi.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system safety practices. Depressurize and lock out the air supply line before removing or installing the regulator. Ensure all NPT threads are properly sealed with thread tape or sealant rated for compressed air service. Verify that the upstream supply pressure does not exceed 300 psi and that downstream components are rated for the adjusted output pressure range.
