There are a couple of things, from dish washing liquid, petroleum jelly, silicone to specialised stuff like Loc Tite special lubricant.
Also examine the bore and the ring groove. The bore, apart from being smooth and clean, should have a little chamfer to guide the ring in place, and the O-ring groove also a small chamfer to prevent a sharp corner trapping the ring.
The trick, when fitting O-rings is to lubricate well (the bore as well as the ring), press and turn in one motion and make sure your aim is in line with the bore.
Once in place a small retraction and subsequent re-press, will make sure the ring settles in the middle of the groove.
If you have avoided nicking the ring, it should now seal for many years to come, as the rubber is now in compression from all sides. It is a very good sealing method when done correctly.
