Rainfall shower compression joint missing.

[jonesey10]

Hello all, hope someone can help I'm after a joint which was missing from a purchase i bought years ago, just getting round to fitting it now, any idea where I can get one?
Pipe inlet is 18mm diameter and thread is 3/4" BSP

Sounds like a strange size?

Why not contact the manufacturer, save a lot of trouble.

That piece is just a decorative cover. Are you missing a wall plate fixing kit.
