The PARKER P3YKA00RR is a replacement diaphragm kit designed for use with Parker P3Y series filter/regulators and regulators in compressed air FRL (Filter-Regulator-Lubricator) assemblies. The kit restores proper pressure regulation by replacing the worn or damaged diaphragm — the primary sealing and sensing element inside the regulator body. This is a relieving-type diaphragm kit, meaning the regulator it services supports downstream pressure relief when inlet pressure drops. Weighing 0.5 pounds and packaged as a single kit, it is a direct OEM-style service part installed by pneumatic system technicians, maintenance mechanics, and industrial service professionals.
This diaphragm kit is intended for service and repair of Parker P3Y series regulators and filter/regulators used in compressed air distribution systems. Typical applications include industrial process lines, manufacturing equipment, and pneumatic control panels where regulated air pressure is required. The kit is suited for both planned maintenance intervals and unscheduled repairs when regulator performance degrades due to diaphragm wear, cracking, or rupture.
Designed for use with Parker P3Y series regulators and filter/regulators as stated by the manufacturer.
Installation is performed by qualified pneumatic system technicians or maintenance personnel. Always depressurize the compressed air line and bleed all downstream pressure before disassembling the regulator body. Follow the Parker service documentation for the P3Y regulator to ensure correct diaphragm orientation and reassembly torque sequence. Verify system pressure and regulator function after reassembly before returning the line to service.
