Where can I find compatible fittings?

[Ted808]

This a mix of material pipework and sizes. It's steel (what size?) and 35mm copper 28mm copper. I need to replace the leaky bit and tidy it up if I can.
Where can I get the reducer from what I think is 2" steel to 28mm copper?
Any pointers?

That’s a union so just needs stripping and pasting

Can I get a threaded connection, to replace the union? What would it be called? Female iron 2" and MI 35mm ?
The leaking bit isn't the union. There's 35-28 copper reducer coupler that probably wasn't soldered and the fella wants the pipe work nearer the ceiling. So, that's why I'm looking to replace the union if i can, but I don't know, what size or where to buy tehm.

Reducing iron socket 2" (if that's what it is) x 1", then 1" x 28mm compression straight or elbow, whatever suits the new layout.

For iron you'd need Pipe Centre or BSS or other independent iron pipe and fittings supplier.

Similar to this,
