The PARKER P01174 is a replacement 60 psi spring designed for use in FRL (filter-regulator-lubricator) assemblies. The spring is the internal pressure-setting component inside an FRL regulator, and it determines the maximum regulated outlet pressure. This part maintains consistent downstream pressure control in pneumatic systems. It is installed by industrial technicians, HVAC mechanics, and pneumatic system specialists during routine regulator service or repair. The maximum working pressure rating is 60 psi, making it appropriate for standard low-to-medium pressure pneumatic applications.
This spring is intended for FRL regulator units operating in compressed air systems where precise pressure regulation is required. Typical install scenarios include air compressor distribution lines, pneumatic tool supply circuits, and HVAC pneumatic control systems. It is suited for both light commercial and industrial environments wherever Parker 14R, E, or 15R Series FRL regulators are in service.
Designed for use with Parker 14R, E, and 15R Series FRL regulator assemblies.
Installation should be performed by a qualified technician familiar with pneumatic system service. Before replacing the spring, isolate and fully depressurize the air supply line and bleed all downstream pressure from the regulator. Reassemble the regulator body according to the manufacturer's service documentation and verify correct pressure setting before returning the system to service.
