This replacement seal is a high quality OEM sourced item that is specially designed for Senco nailers. It is used to provide a tight seal between the cap assembly and the firing valve. Please note this part is made from durable hard rubber material and it is sold individually. Replacing this seal you will need a hex key which is also called an allen wrench.

This retainer is supplied directly directly from the original equipment manufacturer. Constructed of flexible plastic, this item is made for use with several nailer devices. The retainer is fitted between the washer and the cylinder. The retainer helps to absorb the impact of the nailer. A wrench set is necessary for the replacement. The retainer is sold individually.

This is an authentic replacement part that is supplied directly from the original equipment manufacturer for use with Senco nailers. It is the special component which helps to provide an air-tight seal for the valve assembly, over time it may wear out and begin to crack eventually requiring a replacement. Please note this durable rubber seal is sold individually.

Restore strong, consistent stapling performance with this staple driver blade, the component responsible for driving staples into the work surface during each firing cycle. Featuring a durable 3/16" countersunk (CSK) profile and hardened steel construction, it is built to withstand repeated impact and demanding jobsite use. Replacing a worn, bent, or broken driver blade can help eliminate misfires, improve staple penetration, and restore reliable tool operation. Installation typically involves disassembling the cylinder assembly, removing the existing driver blade, and securing the replacement component before reassembling the tool.

Genuine Senco replacement part, this part is sold individually. The purpose of this part is to create a seal so air does not leak from the gun. When replacing this Seal it is advised to inspect all of the other Seals and O-Rings for wear.

This firing valve piston assembly is a critical component of the pneumatic firing system, controlling the flow and release of compressed air required to drive fasteners and reset the tool after each firing cycle. Constructed from durable metal, engineered plastics, and high-quality rubber seals, the assembly helps maintain proper internal air pressure while ensuring smooth, consistent tool operation. When the trigger is activated, the valve assembly directs compressed air through the firing system to drive the piston and fastener, then helps manage exhaust airflow to prepare the tool for the next cycle. Replacing a worn, damaged, or leaking firing valve assembly can help resolve issues such as continuous air leaks from the exhaust, weak driving power, inconsistent firing, loss of pressure, or failure to cycle properly. Installation typically involves removing the top cap assembly, replacing the existing valve assembly, and reassembling the tool using standard hand tools. For best results, inspect the head valve, O-rings, cylinder sleeve, piston, and related sealing components for wear or damage and replace any faulty parts as needed to ensure reliable performance and long-lasting pneumatic operation.

Help keep your tool operating reliably with this pin assembly, an important component that attaches to the piston and helps secure the driver in place during operation. Made from durable metal, it supports proper alignment of the driving mechanism for consistent fastening performance. Replacing a worn, damaged, or missing pin assembly can help restore smooth tool function and maintain dependable operation. Because component placement may vary between models, refer to your tool's parts diagram or service manual to confirm the correct installation location before assembly. Installation typically requires removing the existing pin assembly using a hex key and securing the replacement component in place.
