This part is an OEM from DeWALT. The plastic O-ring has been designed for use with several nailer devices. This item is fitted onto the cylinder, securing the component in the nailer. The O-ring is sold individually. A hex key is often needed for the repair.
Removed the screws from the top cap and replaced all of the worn o-rings. Cleaned the internal parts of the gun and oiled it. Then installed the top cap back on. Works like a new nail gun now.
