No EMT Fitting is Listed as Raintight!
At the local International Association of Electrical Inspectors chapter meeting we learned something I thought you should hear about. Feel free to pass the word.
Currently (June 2003), no manufacturer is authorized to mark their Listed compression type EMT fittings with the "Raintight" marking.
There are no raintight electrical metallic tubing (EMT) fittings approved by any nationally recognized testing laboratory at this time. No matter what the box or packaging says. Most manufacturers have removed the listing information, others have not.
Issue will be big deal in some jurisdictions and a non-issue in others (NEC 90-4 and 90-7). Be advised.

Mike Holt's Comment: I wonder if compression type threadless fitting for Rigid Metal and Intermediate Metal Conduit are listed for this purpose?
