Parker PPS1-1C3-RWL Frl Pressure Switch 250 Psi

Product Description

The PARKER PPS1-1C3-RWL is a brass FRL pressure switch designed for use in compressed air filter-regulator-lubricator systems. It monitors line pressure and signals downstream controls when pressure reaches a set threshold, making it a key component in pneumatic circuit protection and automation setups. The switch features a 1/4 inch NPT port, an adjustable sensing range of 20 to 120 psi, and a maximum working pressure rating of 250 psi. Its brass construction provides solid corrosion resistance in typical industrial air service. Licensed pneumatic system technicians and industrial maintenance professionals are the primary installers.

This pressure switch is suited for use on compressed air systems in light industrial, manufacturing, and process automation environments. It mounts directly to FRL assemblies or inline in pneumatic circuits where pressure monitoring and discrete switching output are required. The 1/4 inch NPT port size makes it compatible with standard quarter-inch pneumatic fittings and tubing commonly found in shop air and automation panel builds. Applications include machine interlocks, low-pressure alarms, and compressor control circuits.

Key Features

• Brass body construction for corrosion resistance in compressed air service
• 1/4 inch NPT port for direct integration with standard FRL assemblies and pneumatic lines
• Adjustable sensing range of 20 to 120 psi to suit varied system setpoints
• 250 psi maximum working pressure provides a safe operating margin above typical shop air pressures
• Compact form factor suitable for panel-mount and inline pneumatic circuit installations

Compatibility

Designed as an OEM-style replacement or add-on pressure switch for standard FRL assemblies and pneumatic systems using 1/4 inch NPT port connections.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems professional. Depressurize and lock out the air supply before installing or replacing the switch. Use appropriate thread sealant rated for pneumatic service on the NPT threads and avoid over-tightening the brass fittings. Verify the setpoint adjustment is within the 20 to 120 psi sensing range before returning the system to service.
