Senco BF0156 Piston Bumper Replacement Part for Stapler SNS45, SNS45XP, SNS45XP16Ga

The Senco BF0156 Piston Bumper is a replacement internal component designed for compatible pneumatic construction staplers. It works within the firing mechanism to cushion the piston at the end of its stroke, helping absorb impact and support consistent fastening performance. Made of durable rubber, it is designed to withstand repeated contact and pneumatic cycling during normal stapler operation. It is suitable for replacing a worn or damaged bumper during construction stapler repair, rebuilding, and routine maintenance. Compatible models include Senco SNS45, SNS45XP, and SNS45XP16Ga 16 Gauge Construction Staplers, and for safe installation, disconnect the stapler from its air supply and release residual pressure before servicing.
