It is a genuine OEM item that is made for DeWALT demolition hammers. This is a special component which helps to provide a tight seal between the piston and the cylinder. Over time it may wear out or get damaged eventually requiring a replacement. A worn o-ring can cause low compression and poor performance. Make sure to check the appropriate diagrams for your model to ensure the proper repair procedure. It is made of durable material and is sold as an individual item.
