This item is available as an individual replacement part. The cylinder sleeve fits between the piston driver assembly and the check seal. This part is an original part from Bostitch for use in nailers and staplers. It is made out of plastic and will require replacing if it breaks. A set of pliers and an allen wrench may be needed when replacing this sleeve.
If you\'ve already diagnosed the issue, mine being that the nail gun wouldn\'t fire a nail, then this repair is very simple. I have the Bostitch BT-1855 18 gauge nailer. First you will need to remove the cap and (4) Allen head screws at the rear of the gun (part #181917, or item 2 if you are looking at your factory schematic which is the

You should see a clear bumper, spring and O-rings. You shouldn\'t need to replace these. You will need to remove and replace items 10-16 on your schematic. They are as follows: 10-piston driver (#180451) 11-piston ring (#180457), 12-cylinder sleeve (#180458), 13-O-ring (#180459), 14-check seal (#180460), 15-bumper (#180461), 16-driver guide (#180462). I pulled everything out and lined it up just as it went into the nailer, so as not to forget the original placement and mechanics. Remove your replacement parts from their packaging. Assemble items 10-16 together, then place the completed assembly into the gun; rather than putting each individual item back in place. Reattach frame cap seal and frame cap. Test fire gun. All told it should take about 15-30 minutes to complete this repair. You should only need the appropriate size Allen wrench and maybe a small flat head screw driver for prying some of the O-rings out.
