CCG Industrial and EExde Adaptors, Reducers and Plugs

 
Differing Entry Threads
Because electric apparatus could originate from foreign 
countries, various threads are encountered. It is therefore necessary to fit such threads with the appropriate adaptor. Although glands can be manufactured with special threads, it still leads to the problem that if the gland is replaced later the problem with the original foreign thread entry remains. An adaptor, however, can stay permanently in place.

PG Threads (DIN German Standard)
Equipment originating in Germany, Switzerland and most European countries are supplied with a PG thread.
The letters PG stand for ‘‘Panzerrohr Gewinde’’.

NPT threads National Pipe Taper (USA)
Since the sizes 1/2" NPT-3/4" NPT-1" NPT are close to I.S.O. metric threads, it is very easy to mistake them as such. An interface between NPT and metric will, however, not form a flameproof path and fitting a gland direct could lead to disaster.
