Function of the Seal Collar
The 910807 Collar is designed to:
- Seal the upper air chamber of the nailer
- Maintain proper pneumatic pressure during operation
- Provide spacing between internal head components
- Help ensure proper piston return and cycling
- Reduce internal air leakage
- Restore consistent firing performance
A properly functioning seal collar is essential for maintaining the nailer's pneumatic efficiency and dependable operation.
Common Signs Replacement Is Needed
Replace the seal collar if you notice:
- Air leaking from the top of the nailer
- Cracked, split, or deteriorated rubber collar
- Nailer fails to cycle properly
- Driver does not return correctly
- Reduced driving power
- Internal rubber pieces found inside the head assembly
A deteriorated collar commonly causes air leaks and firing issues as the neoprene material naturally breaks down over time.
Installation & Service Notes
Disconnect the nailer from the air supply and remove all fasteners before servicing.
Remove the head cap by loosening the retaining screws with the appropriate hex key. Remove the worn 910807 Collar and clean any deteriorated rubber or debris from the head assembly. Install the new collar in the correct orientation, ensuring it is fully seated before reinstalling the head cap. Tighten the fasteners evenly and reconnect the air supply to verify proper sealing and normal firing operation. Basic hand tools, including a hex key and pliers, are typically all that are required for installation.
Important: Always verify your nailer model and original part number before ordering. Inspect related O-rings and seals whenever the head assembly is disassembled, as multiple sealing components may wear together. Use genuine OEM Porter-Cable replacement parts to maintain factory fit, proper air sealing, and long-term pneumatic performance.
Maintenance Recommendations
- Lubricate the nailer regularly with pneumatic tool oil.
- Periodically inspect internal seals for wear or deterioration.
- Keep moisture and debris out of the air supply.
- Replace worn O-rings and seals during routine maintenance.
- Use clean, regulated compressed air for optimal performance.
- Use genuine OEM replacement parts to maintain factory fit, dependable sealing, and long-term roofing nailer performance.
