Has anyone ever used vented caps such as those produced by Performance Systematix Inc? These have liners made of expanded PTFE that are liquid tight but allow gases and vapors to permeate, thus reducing pressure build up. They are normally used to replace standard chemical container caps for chemicals that offgas. If you've used them what is your opinion of them? Do you know of other sources of vented caps (i.e., other than Performance Systematix Inc)? Regards Larry
