Yes, this is pretty close to mine. I don't use those fittings to mate the two tubes, just "screw" them together and duct tape them. Make sure the inside edge is pointed away from the fog machine.

Also, mostly for convenience, but ease of hookup too, I place the entry point high up on the trash can, with the fogger on the table. Does this help the operation? I have no idea, but I don't even need to seal the fog machine to the dryer tube.

FWIW
