This is a genuine manufacturer-sourced replacement part which is made for use with Hitachi nailers and staplers. It helps to distribute the pressure evenly and provide a tight seal for the head cap. Over time it may become brittle and begin to crack eventually requiring a replacement. For the proper application please refer to the appropriate diagram of your model. This high-quality part is made of durable rubber material and is sold individually. You will need a screwdriver to remove the head cap in order to perform this repair.
