If your Porter-Cable brad nailer or stapler is losing power, leaking air, or just not firing like it used to, this overhaul kit is probably the fix you need.


This is a direct replacement for the OEM 903775 rebuild kit.
It includes all the internal seals, O-rings, and gaskets you need to breathe new life into your tool – basically, it's like giving your nailer a tune-up.


Before ordering, double-check your model number and compare the parts in the pictures to make sure it's the right fit.
If you're not sure, shoot them a message – they're responsive and helpful.
This is a cheap way to save a perfectly good nailer instead of dropping cash on a new one.
