Parker PPS1-1C3-RHM Frl Pressure Switch 1/4 in 250 Psi

Product Description

The PARKER PPS1-1C3-RHM is a brass FRL pressure switch designed for use in compressed air and pneumatic filter-regulator-lubricator assemblies. It monitors system pressure and provides a switching signal when pressure reaches a set threshold, making it a reliable sensing component for automated pneumatic control circuits. The port size is 1/4 inch NPT with a maximum working pressure rating of 250 psi. The unit is compact, with a height of 4.3 inches and a cross-section of 1.13 inches x 1.13 inches, and weighs 1 pound. Licensed plumbers, pipefitters, and pneumatic system technicians are the typical installers for this type of component.

This pressure switch is suited for industrial and commercial pneumatic systems where pressure monitoring at an FRL assembly is required. It is typically installed inline at the outlet of a filter or regulator to verify that downstream pressure remains within acceptable operating limits. The 1/4 inch NPT connection makes it compatible with standard quarter-inch pneumatic plumbing used widely across compressed air distribution systems in light manufacturing, HVAC equipment rooms, and process facilities. The DIN-rated 0-120 psi sensing range covers common shop air and instrumentation air applications.

Key Features

• Brass construction for corrosion resistance in pneumatic service environments
• 1/4 inch NPT port matches standard FRL and compressed air plumbing fittings
• 250 psi maximum working pressure supports a wide range of shop and instrumentation air systems
• 0-120 psi DIN sensing range suitable for typical compressed air control applications
• Compact form factor at 4.3 inches tall and 1.13 inches wide fits space-constrained panel and manifold installations

Compatibility

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

Installation Notes

Installation should be performed by a qualified pipefitter, pneumatic technician, or licensed plumber. Depressurize the system completely and lock out the compressed air supply before removing or installing any pressure switch. Use appropriate thread sealant on NPT connections and verify that the downstream system pressure does not exceed the 250 psi maximum working pressure rating of this switch. Verify electrical connections to the switch output comply with applicable NEC requirements for the control voltage being used.
