 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.
