Flanges Surrey or York?

I need a flange for the hot water cylinder and it looks like a 22mm compression nut screwed onto it.

I think I need a York flange for this, am I right?

Is that a 1" male thread on the cylinder?

22mm compression thread is a bit of an oddball.

From what I can tell, York and Surrey are both used for (pumped) showers. York is male thread; Surrey female, both 1" BSP (roughly 33mm OD). Is that your application?

I think it's more like a 3/4" npt
