    Hi all

    Struggling to find a new hose for this unusual union on a grohe deck mixer it almost looks like a outside tap hose lock, it’s not threaded at all, just a male spigot with an o-ring.

    Looks like it's a special grohe one but it looks like it might unscrew so you can install a standard connection

    It looks like a grohe shower connection. I’ve seen one like that it had a 15mm chrome pipe connected to it.
