bending 18mm brass tube

[RaceDiagnostics]

Any suggestions on how to put a 90 degree bend into this 18mm OD brass pipe in the direction of my finger? I plan to add a motorised valve into my heating system so need to divert the pipework a bit.

90% 15mm plumbing fitting and solder it
doubt you would bend that due to age

What's the internal diameter? Would a 15mm bend solder inside the pipe?

I tried a 15mm copper pipe in it and there was a fair amount of wobble.

I wonder if this would fit?

states silver solder not soft solder no ref to internal or external size you would have to buy one to try
if you tinned a 15mm fitting that would take up the internal bit of slop then solder it in

Solder a brass 15 mm olive in the gap.

It looks like 18mm copper pipe fittings are fairly easily available, I'd never come across them before.

Make sure they are quoting OD and not bore.

The 18mm fittings worked perfectly.
