Sealey Supermig 180/1 Gas valve thread size

[Dogmatix]

Hi
I have a Sealey SuperMig 180/1.
I want change the inlet / outlet fittings on the gas valve but I have no idea what threads are used on the existing ones. There seem to be a few different threads used on gas valves.
Can anyone enlighten me as to the thread size on the Sealey or how to measure the threads?
Regards
Dave

A caliper gauge plus a copy of the Zeus engineering reference book should get you close:

Zeus Reference Book

This is the popular small pocket booklet that is the reference book for fitters, metal workers and draftsmen. It is printed on stiff card, with a protective plastic coating that makes it very durable for use in the workshop. The tabulated data includes...

Confirm the thread size using a thread gauge.

Or post an image of the threaded part, next to a decent ruler. The collective wisdom here should be able to make a reasonable guess.

Hi Voipio,

I'm sorted now.
I went to remove the inlet side hose to access the valve inlet and surprise, surprise, it's the very fitting I was going to change it to.
The previous owner had, obviously, renewed the hose but fitted the wrong one and created an abortion of glue and insulating tape to make it fit.
Fortunately it's all come away without any damage.
Lesson learned too. Have a proper look before making yourself look an assh*le on a forum. Granted I didn't want to remove it till I had replacements in case I needed the welder.
Thank you for your help and suggestion, much appreciated.
Regards
Dave

You haven't made yourself look an assh*le on a forum. Far from it. And something to remember is, there's no such thing as a stupid question:

Thanks for the kind words.
I have to admit I felt a bit of a twit for not checking properly though before posting on here.
