Most orings are designed for use without lube. In a static situation lube should not be needed. Most often a light coating of lube is used when the oring is needing to be placed in a tight fitting area lessening the chance of stretching the oring.
In places where lubing the oring is needed the manual will tell you.
Remember lube can be used to help things move smoothly but it also is a dirt magnet. Using the incorrect lube for a specific oring material can also cause premature oring failure through chemical interactions.
Personally if lube is not called for I do not use it. The use of lube when direct is often to help prevent damage to the oring in frequent friction case like the oring on dive camera orings where it is being opened and closed frequently.
