Senco 70003 Bumper Replacement Part

Product Description

The SENCO 70003 is an OEM-authorized bumper replacement part designed for use in Senco pneumatic nailers and fastening tools. The bumper serves as a critical wear component inside the driver assembly, absorbing impact at the end of each firing cycle and protecting the tool body from metal-on-metal contact. At 0.25 pounds and measuring approximately 0.98 inches on each side, this compact part is a direct OEM replacement that restores tool function when the original bumper becomes worn, torn, or compressed beyond spec. Installation is typically performed by tool repair technicians or experienced trade professionals performing in-shop maintenance.

The SENCO 70003 bumper is suited for use in Senco pneumatic fastening tools where the original bumper has degraded, causing incomplete driver return, excessive noise at bottom-out, or visible deformation of the part. Replacing a worn bumper at the first sign of damage prevents further wear to the driver blade and cylinder components, extending overall tool service life. This part is appropriate for both shop-based repair and field service situations where a spare is stocked.

Installation Notes

Bumper replacement should be performed by a qualified tool repair technician familiar with pneumatic fastening equipment. Before disassembly, disconnect the tool from the air supply and discharge any residual pressure from the system. Refer to the Senco service manual for the specific tool model to follow the correct disassembly sequence, as internal driver components are under spring tension. Do not reuse a bumper that shows cracking, permanent compression set, or material loss.
