Driver Cpl. HY00000018

This genuine replacement piston driver assembly is sourced from the original equipment manufacturer for use with Makita nailers. It is the part of the nail gun that drives the nail into the material that is being used. These assemblies do have a tendency to bend or break if not used correctly or if you are driving nails into an extra hard material. Please note this assembly includes a metal piston with the driver and it is sold individually, please note the o-ring is sold separately.
