Dewalt 52172-pwr Retaining Ring P3500 P35S

Product Description

The DEWALT 52172-pwr is a retaining ring designed as a direct OEM-replacement internal component for DEWALT pneumatic nailers. Retaining rings secure rotating or sliding parts within a tool assembly, preventing axial movement and maintaining proper alignment during operation. This part is installed by tool repair technicians and experienced power tool service professionals working on DEWALT framing and finishing nailer platforms. It is a small but critical fastener-class component — failure or wear of the retaining ring can cause internal components to shift, resulting in misfires or tool malfunction.

This retaining ring is intended for use in DEWALT P3500 and P35S series pneumatic nailers. It is a service and repair part, typically replaced during a full tool teardown or when internal component wear is identified during inspection. Having the correct OEM part number on hand reduces downtime during tool servicing.

Installation Notes

Installation should be performed by a qualified tool repair technician familiar with pneumatic nailer disassembly. Disconnect the tool from its air supply and discharge any stored pressure before beginning service. Retaining rings typically require snap-ring pliers of the appropriate size and type — do not attempt installation with substitute tools, as ring distortion can cause improper seating. Refer to the DEWALT service manual for the specific nailer model before disassembly.
