Product Description

?

This is a genuine manufacturer-sourced replacement part which is specially designed for Bostitch staplers. The purpose of this piston bumper is to keep the piston from hitting the bottom of the cylinder and damaging it. Because this part gets so much abuse, over time it has a tendency to crack and fall apart. Please make sure to refer to the appropriate diagrams of your model for the correct location and application of this component. Keep in mind this high-quality item is made of durable material and is sold individually.

I removed the rear cap on the cylinder with an adjustable crescent wrench and pried the old bumper/piston stop out. The bumper had deteriorated and was chipping apart and was indeed causing the piston to return off-center which prevented the driver from extending out and driving the staple. I lightly coated the new bumper with oil and pre ssed it into the rear cap using a small socket and a pair of pliers. I reinstalled the rear cap, tightened it, and the stapler is working perfectly.
