Function of the Cap Gasket
The 395376-00 Cap Gasket is designed to:
- Seal the connection between the head cap and nailer frame
- Prevent compressed air leaks during operation
- Maintain proper internal operating pressure
- Support consistent piston movement
- Restore factory sealing performance
- Help maximize nail-driving efficiency
Using a genuine OEM replacement gasket helps ensure proper air pressure and dependable pneumatic tool performance.
Common Signs Replacement Is Needed
Replace the cap gasket if you notice:
- Air leaking from the top of the nailer
- Torn, cracked, or compressed gasket material
- Reduced driving power
- Inconsistent nail depth
- Compressor cycling more frequently during use
- Gasket damage discovered during routine maintenance
A worn or damaged head gasket can reduce air pressure inside the tool, leading to poor performance and inefficient operation.
Installation & Service Notes
Disconnect the nailer from the compressed air supply and remove all fasteners before servicing.
Using the appropriate Allen wrench, remove the head cap fasteners and carefully lift off the cap. Remove the worn 395376-00 Cap Gasket and clean both sealing surfaces thoroughly to remove old gasket material, oil, and debris. Position the replacement gasket correctly between the cap and frame, then reinstall the head cap and tighten the fasteners evenly in a crisscross pattern to ensure a uniform seal. After reassembly, reconnect the air supply and check for leaks before returning the tool to service.
Important: Always verify your nailer model and original part number before ordering. Whenever the head assembly is disassembled, inspect nearby O-rings and seals for wear and replace them as needed to maintain optimal pneumatic performance.
Maintenance Recommendations
- Inspect the head gasket whenever the cap is removed for service.
- Keep sealing surfaces clean and free of debris.
- Tighten head cap screws evenly to maintain a proper seal.
- Replace worn O-rings and seals during major maintenance.
- Use clean, dry, regulated compressed air for best performance.
- Use genuine OEM replacement parts to maintain factory fit, airtight sealing, and long-term pneumatic nailer performance.
