Parker P04427 30 Psi Spring 05 Re Series Frl

Product Description

The PARKER P04427 is a replacement pressure spring rated at 30 psi maximum working pressure, designed for use within Parker FRL (Filter-Regulator-Lubricator) assemblies. FRL springs set and maintain the regulated outlet pressure in pneumatic systems by resisting the diaphragm against downstream air demand. This spring is a direct service part intended for field replacement when the original spring loses calibration, fatigues, or is damaged during maintenance. Licensed pneumatic technicians and industrial maintenance professionals typically handle this type of repair. At 0.1 pounds, the part is lightweight and easy to stock as a service spare.

This spring is specifically designated for use with Parker 05 RE Series FRL units. It is suited for light-duty pneumatic control circuits, instrument air systems, and compressed-air tool circuits where regulated pressure must be held at or below 30 psi. The 05 RE Series is a compact FRL platform commonly found in industrial automation panels, machine tool enclosures, and process control skids. Replacing a worn or out-of-spec pressure spring restores accurate regulation without requiring full unit replacement.

Key Features

• 30 psi maximum working pressure rating matches OEM specification for 05 RE Series regulators
• Direct OEM-style replacement minimizes downtime during scheduled or corrective maintenance
• Lightweight at 0.1 pounds for easy handling and parts-kit inclusion
• Single-piece packaging allows individual unit repair without surplus inventory

Compatibility

Designed for use with Parker 05 RE Series FRL assemblies requiring a 30 psi pressure spring. No other compatible models or part numbers were specified in the product data.

Installation Notes

Spring replacement in an FRL regulator should be performed by a qualified pneumatic technician or industrial maintenance professional. Before disassembly, isolate the unit from the compressed-air supply and verify system pressure has been fully relieved downstream. Avoid over-compressing the spring during reassembly, as improper seating can cause inaccurate pressure regulation or regulator body damage. Verify outlet pressure with a calibrated gauge after reassembly before returning the system to service.
