Parker PS4038166CP Air Regulator 125 Psi Sandwich Manifold

Product Description

The PARKER PS4038166CP is a sandwich manifold compressed air regulator rated for a maximum supply pressure of 125 psi. Built from zinc, this regulator mounts inline within a manifold stack and controls downstream air pressure across pneumatic systems. It includes an integrated relief function and a 1/4-inch gauge port for direct pressure gauge attachment. The operating temperature range runs from -5 degrees F to 120 degrees F, making it suitable for standard industrial and facility compressed air applications. Licensed pneumatic technicians and industrial maintenance professionals are the primary installers of this component.

This regulator is designed for use in compressed air distribution systems where a sandwich or manifold-style mounting configuration is required. Its compact footprint of 4.5 inches wide by 10 inches high fits within modular pneumatic filter-regulator-lubricator assemblies commonly found in manufacturing, automation, and process control environments. The built-in relief function vents excess downstream pressure when the set point is exceeded, protecting sensitive downstream components.

Key Features

• Maximum supply pressure of 125 psi for standard compressed air service
• Sandwich manifold regulator type for inline manifold stack integration
• Built-in relief function for downstream overpressure protection
• Pressure gauge port included with 1/4-inch thread size
• Zinc construction for durability in industrial environments
• Operating temperature range of -5 degrees F to 120 degrees F

Compatibility

Designed as an OEM-style replacement or expansion component for modular sandwich manifold compressed air regulator assemblies using Series 1 configuration.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize and lock out the compressed air supply line completely before disassembling any manifold components or replacing this regulator. Verify downstream system pressure ratings are compatible with the regulator set point before returning the system to service. Follow applicable OSHA compressed air safety guidelines and local facility procedures during installation.
