BUMPER-PISTON STOP 174075

This genuine OEM piston bumper is designed to cushion the piston as it retracts into the cylinder after firing, helping protect your nailer from wear and tear. Made from durable plastic, it’s built to withstand repeated impact—but over time, it can crack, break apart, or fall out due to heavy use. If you notice damage or missing parts, it’s time for a replacement. This part is sold individually and is not an aftermarket substitute. To install the new bumper, you’ll need a hex key (also known as an Allen wrench). Begin by removing the tool’s cap and accessing the cylinder. Once the piston is removed, you can take out the old bumper and place the new one securely at the bottom of the cylinder. Reassemble the tool by reinserting the piston and cylinder, then fastening the cap back into place with the screws. This quick repair helps restore your nailer’s performance and extend its lifespan.
