I've tried R3603 and some harder cheapo noname 1/2".
If you put it in near boiling water and then stretch it with a plier you can easily get 1/2" OD tubing over 5/8" OD barbs. When it cools it shrinks and you have to cut it loose. If you put it in cold water while stretching it, it holds the stretched shape.
