Yes, it depends on the material used. It also depends on the fluid(s) you are using as they may deteriorate the superglue over time. Wouldn't that suck?
I make O-rings here at work quite often, but for vacuum purposes. No liquids involved.
You have to make sure that both surfaces you cut are very flat so they mate together properly. You should also sand the cut ends with some fine grit sandpaper (400 - 600 grit) lightly so that the superglue will melt into the surface better and provide a better bond. Clean the ends with a q-tip and isopropyl alcohol (rubbing alcohol) and then some acetone on a q-tip (if you have acetone). You NEED to have the ends clean if you want a satisfactory superglue joint. You do not want the superglue to form a layer on the outer surface of the O-ring as that will compromise the compression in that area of the O-ring, so wipe off any excess that squeezes out. You don't really need to cut the O-ring material at an angle (I just cut straight across for vacuum seals), but it will make for a slightly stronger joint if you do cut it at an angle.
