Hi, I'm trying to locate a Gland that fits this hole and thread, rather than just jam a plastic one in there. Anyone got any idea's as to if they are available from anywhere? I'm having no luck locating one at all.

Standard item from good electrical supplier that sells to the trade.

Visit your local City Elctrical Factors they will likely have something in either plastic, brass or steel. However some old motors I have had some very odd threads which don't match modern standards. The one on my mill dating back to around 1960 I had to tap out to (from memory) 22mm in order to get a gland that would accept screened cable.

Depends on whether it's an imperial (e.g. 3/4 inch x 16 TPI) thread, a metric thread (e.g.M20 x 1.5 pitch) or a Pg thread which goes by the nominal bore size of the conduit.
If you can measure I.d and pitch of the thread in the hole we'd be in with a chance. The other clue is what make and nationality is the motor, and how old?

Looks like a standard 20mm gland - plenty on ebay.
As long as it goes through the hole, mine came with a locknut so perhaps matching the thread is not critical.?

Hi, it's not M20 that's for sure, I've tried it. Its an old Crompton Parkinson motor of unknown age. I suspect its imperial and everything I've looked up is metric. Can't seem to find a stockist of imperial fittings. I know its not really important but would have liked to get the proper fitting gland if at all possible.

Motor threads are "usually" 3/4" Condiut. 750" o.d. x 16 threads per inch, These are NOT BSP.
Condiut is designated by the Outside Diameter.
BSP threads are designated by the nominal bore of the pipe.

|3/4" by 16tpi = 3/4 UNF - dies readily available for this - even if motor is probably Whitworth thread a brass fitting should fit|

looks like 3/4 conduit, which means, no you wont get one anywhere unles you can find an old sparks like me who has some in a tin under the bench! If you have any long established electrical engineers near you, try them!
