Weldgas Regulator

Do any of you brewers use a Weldgas nitrogen reg like the one in the photos? I am having trouble trying to find the right JG fitting for the hose end. The one in the photo is part no. P14512F6S with a 3/8" NPTF thread, which does not go on the reg. I think I need a JG part no. P1451213 with a 3/8" BSP thread, but need confirmation from someone as I am just wasting money buying the wrong bits. Been in touch with Weldgas and the co. that sold me the reg, but still waiting for a reply.
PS Don't seem to be able to attach photos, any help here too please?

Pics aren’t there but for my welding reg i needed this

And a couple of strong wrenches.

Worked fine - bear in mind you won’t get a reading for how much is left in your gas bottle, but that’s not too important as you can do it by weight

haggis51 asked " maybe one of the admin people will be able to tell me how to attach them?"

I'm not admin but to add photos to this forum you need to save them elsewhere on t'internet and then add the link to that location to your post using the 'Img' button at the top of the Full Editor screen.

An example is this picture of my old 30L boiler - now long gone.

Extensive googling hasn’t returned much - try phoning weldgas (likely they're running from an industrial estate and don’t answer the phone, as is the norm with these sorts of places) or JG directly.
