Q for a plumber

I desperately need one of these and ideally today. Anyone know where I can walk in and get one?

I’m in Sydenham.

Could you just get a 15mm to 3/4" braided hose connector and an elbow (if you need one)?

Cheers mark that’s exactly what I did in the end just without the elbow as not needed.
