Piston Bumper 887170

This replacement piston bumper is an authentic OEM item. It is specially designed for Hitachi nailers. This part acts as a cushion when the piston retracts back into the cylinder after being fired. Because this part gets so much abuse it has a tendency to crack and fall apart. If the part is damaged or falls out you will need to replace it. It is made of high-quality material and is sold individually. To complete this repair you would need a Hex key also known as an Allen wrench. Check the owner's manual and the appropriate diagrams for the correct application.
