Dewalt 163820 Head Valve Bumper

Product Description

The DEWALT 163820 is a replacement head valve bumper designed for use in DEWALT pneumatic tools. This small but critical component sits within the valve assembly and absorbs impact during tool cycling, helping to maintain consistent valve operation and extend the service life of the tool head. Licensed technicians and experienced repair professionals install this part during routine maintenance or when the original bumper shows signs of wear, cracking, or compression failure that affects tool performance.

This bumper is used in pneumatic tool repair applications where the head valve assembly requires replacement components. It is suited for shop or field repair scenarios where restoring proper valve function is the goal. Installers working on pneumatic nailers, staplers, or similar DEWALT pneumatic platforms will encounter this part during disassembly of the tool head.

Key Features

• OEM replacement part sourced directly from DEWALT
• Designed to fit within the head valve assembly for proper seating and function
• Absorbs cyclic impact to protect surrounding valve components
• Restores consistent valve actuation when worn original bumper is replaced

Compatibility
