They should have a film of whatever fluid they are going to seal on them. Transmission O-rings should have ATF on them.
Brake O-rings should have Brake Fluid on them.
If it is something using Grease, Grease the O-rings.
And, so on.
The exception would be if you have some special O-ring Lube than can be used as the have for Brake Calipers.
The one place I worked during Fuel Injection Pumpy assembly we use a mix of 50% Motor Oil and 50% STP.
