Need help finding fitting

[AP2]

Does anyone know where I can find this fitting or one similar to it in size?

Really depends where on Earth you are. Link below is one place.

What thread / pitch does it have? Might be able to cross-reference to another brand male to male adaptor if we knew exactly what it is.
