well the 1/2"od's if you can get them in 1/4npt would be awesome.
the main advantage of these fittings, is the much smoother flow-path, compared to that of the normal barbs style fittings.
those in the picture is 3/8 od and I got them for the U1 project i'm doing... reason for them is, that there is not much space for a full length barb to fit in.
