Parker P3YKA00RN Frl Diaphragm Kit P3Y Regulator

Product Description

The PARKER P3YKA00RN is a replacement diaphragm kit designed for use with Parker P3Y series filter/regulators and regulators in compressed air and pneumatic systems. The diaphragm is a critical internal component that controls pressure regulation by responding to downstream pressure changes. When a diaphragm fails or degrades, the regulator loses the ability to maintain accurate outlet pressure, making timely replacement essential for system performance. This kit is the OEM-specified service part for restoring regulator function. Installation is typically performed by pneumatic system technicians or industrial maintenance professionals.

This diaphragm kit is suited for maintenance and repair of Parker P3Y series FRL components found in compressed air distribution systems across industrial, commercial, and manufacturing environments. It is appropriate for scheduled preventive maintenance intervals or unplanned repairs when regulator performance degrades. The non-relieving design characteristic of the P3Y series is preserved with this replacement kit, meaning downstream pressure must be bled manually before servicing the regulator.

Key Features

• OEM-specified diaphragm replacement for Parker P3Y series regulators and filter/regulators
• Non-relieving regulator compatibility — downstream pressure bleed required before disassembly
• Compact kit dimensions of 3.5 inches x 3.5 inches x 3 inches for easy storage and handling
• Single-unit packaging allows per-unit repair without excess inventory
• Restores accurate pressure regulation function when original diaphragm is worn or damaged

Compatibility

Designed for use with Parker P3Y series regulators and filter/regulators as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician familiar with compressed air FRL components. Before disassembly, shut off the upstream air supply and fully bleed downstream pressure from the system — this is especially important given the non-relieving design of the P3Y regulator. Refer to the Parker service manual for the P3Y series for proper disassembly sequence and torque guidance. Inspect seating surfaces for wear or debris before installing the new diaphragm.
