-Extreme Associates never use condoms in their movies. They actually had a promotional campign promoting that fact they they don't use them.
-Red Light District
Those are the only ones I can think of off the top of my head. There are other companies that use them in some movies but not others, what I mean is that occasionally you will see a condom in one scene from a movie put out by lets' say West Coast productions, but it will only be the one scene, the rest would be condom free, I guess the girl specificaly requested the guy use a rubber.
I believe Tricia from Evil Angel posted here that the performers that take part in their productions have the option to use them or not, however you usually you don't see condoms in Evil Angel titles with the exception of the shemale series,the occasional Brazililian shot porn (although not all of them), and once in a while you will see maybe one scene from an American Evil Angel movie that has a condom.
West Coast productions also has quite a few movies that use no condoms.
You can aslo count on most European porn to have no rubbers
