Try stretching the hose with a pair of needle-nose or long-nose pliers. Dip it in the hot water, the push the pliers in, open up the pliers to stretch the hose, then shove it onto the barb. That way you get the hose much further over and will get a better seal. It's best to do it all in one go if you can be quick (i.e. without re-dipping it in the water).
I've done that for all my fittings (pretty much all barb except for the JG check valve), and my system is prefectly sealed.
w00t!
