the size was just what i needed. It looks like the measurements listed are the widest part of the barb, not the actual inner diameter of the hose you will be using it in. I needed a larger size than my hose to get a really snug fit as I've been using it for diesel. Lines when installing a two-stage heater. Works great, the heating works thanks to this fitting.
