Product Description

This is a manufacturer-approved piston assembly, which includes an assembled piston and driver. The function of the piston is to push the driver down the cylinder, which drives nails into the object being worked on. The most typical reason the piston assembly needs to be replaced is because the driver is damaged. The tip of the driver tends to deteriorate over time, causing the nails to jam. If your nailer is no longer driving nails properly, this should be one of the first things checked, especially if you hit something hard, such as concrete or metal.
