Electrician Jobs Threading Conduit Problem

[GarryJ]

Evening,

Wondering if anyone knows where I can source an Imperial Die with a suitable ratchet crimper for a specialist job we need to do.

I have sourced the below but after a bit of research and measuring Im pretty sure the conduit we need to thread is 5/8. Afterwards we can put on a 5/8 adaptor with a 20mm thread and bush it into trunking to remain good earth continuity onto conduit pipe rather than earth camp wrapped around it.

Cheers for any help

If you fancy working your muscles a bit there is this one... (not ratchet)

5/8 is pretty rare nowadays but having said that the site I am at the moment still has lots in use. Have you actually sourced any 5/8 to 20mm adaptors.

just thinking outside box ,if you can remove said conduit take it to local garage and weld a coupler onto it galv spray ,job done integrity complete

5/8 is 16mm if I recall so is it not possible to get a 16mm die and just use a 16 -20mm adaptor as these are more common and easily sourced.

Try Cromwell tools, they have huge range.

That's for pipe thread.
It's no good for Electrical conduit, that's a B.S unique thread;

I'd say the chances of finding a ratchet 5/8" conduit die are Zero.
I'd look for an alternative way.
And the same goes for 5/8" to 20mm

5/8" die here;

Yep, BSP and BSW thread forms,are different. I think the best route for the Whitworth version,maybe going down the collectors/antique route.
On a related topic,i was looking at the Whitworth family bible a while ago,as an elderly pal,knew Joseph Whitworth's great grandmother...a beautiful,leather bound book,with some very nice inscriptions on the inner leafs.
