Kit should have contained one more washer!
This kit allowed me to rebuild my friend's Porter Cable Stapler. However, the kit does not come with a new washer for the trigger mechanism. It comes with the o-ring to seal the trigger, but not the washer. Overall this is an excellent product. Be sure you check the washer that fits into the trigger mechanism, as you will have to replace it if is broken like the one I fixed.

Worked as expected
Worked great, a little pricey for a few “O” rings
