They should work with the wire but I don't think they'll fit through the hole in the still dragon kit. The OD of the threads is 22.5 mm which is approximately 0.93". This is dimension D1 here:http://www.cableglandsdirect.com/pg16.html
The hole size in the adapter is for a 1/2" conduit so the actual diameter should (I haven't measured) be 7/8" or 0.875".
I don't have any PG16 cable glands and haven't tried them with the still dragon kit but I don't think they would work.
