Once you establish that you have the proper end gaps, a hose clamp will work, but I'm not a big fan of using one alone due to the possibility of the nut area scoring the piston. An old trick is to cut up a beer or soda can and wrap that around the ring and then put the hose clamp around that. You only have to tigten the clamp so that the rings are evenly compressed and can start into the chamfer at the bottom of spigot. You should not install the piston/rings into the jug without the piston mounted to the rod. Too easy to screw up installation of the circlip.
