Push Lock hose/fittings

[colospace]

Anyone have an easy process for installing the blue Aeroquip hose onto the Push Lock fittings?
I have only tried one so far using engine oil as a lube and some heat gun heat. Almost have it fully on but not quite, and that was working on the bench, not on the plane. I guess I'll try John McBean's dish soap suggestion on the next one. I have thought about sticking the hose end in some boiling water too.
If it is just going to be a bear to get these on, then I guess I'll have to demount the oil cooler to get the 45 degree Setrab Push Lock fittings I'm using onto the hoses and then install the fittings into the oil cooler.
Three of the fittings on my oil thermostat are just brass barbs (rather than Push Lock). Is getting the blue (Push Lock) Aeroquip hose onto those easier I hope?

I use the boiling/hot water method , hoses slide right on. Its a uniform heating.

+2 on hot water (with a couple drops of dish soap).

I have never used any soap or lube on the hose or fitting , I haven't found it necessary .

Just out of curiosity is that method better than using AN fittings and braided hose? Is there pros and cons of this push on hose?

I prefer the pushlock system. The braid is more difficult to cut cleanly.
