Hey guys!

Just took delivery of a YHM 3-piece modular float tube (barrel nut, jam nut & tube), and the instructions refer to a special tool for tightening the jam nut. Said tool was not supplied with the tube kit, and I haven't found any reference to it in my searches here. It's got flats on it, so it looks like a biga$$ adjustable wrench might work. Anyone know what the deal is?

Am I correct that the barrel nut and jam nut go on, then the tube is screwed down as close as possible and indexed (it's a 4-rail type), then the jam nut is tightened against the tube?

Thanks!

You are correct on how the nut and tube are installed.  As for the tool, if it's not possible to get a strap wrench on you might try getting your rails lined up and tight, then final tightening with a punch or screwdriver against the flats.  Of course with something in between to protect the finish, that's how I had to install my first Cmore tube.
