I have finally given up on trying to source parts for my Grohe Neotherm thermostatic shower and I am now in the process of replacing it.
It appears that I will need to use 1/2" BSP connectors and I have Googled without success for the type of fitting required.
Does anyone know if I would be able to obtain a 1/2" BSP female to 1/2" BSP male straight fitting suitable for domestic plumbing??
The nearest I could find is this fitting
Regards
