New Grohe Kitchen tap

[jmskippy]

We bought a new Grohe kitchen tap, it came with flexible connectors but the end which screws onto the valve is too small. The old flexi tap connector was 22mm and the new is smaller, probably 15mm. I have tried to get and adaptor to no avail. The valve end where the connector connects to is just a bit of thread.
If anyone can understand what I am talking about, any advice would be much appreciated.

I have been to B&Q, Wickes, Homebase, Screwfix and Builder Depot.
A guy at Builder Depot was very helpful and gave me something, it's a connector with a 15mm side to fit the new connector and the other side 22mm with a nut and copper washer. He said I would need some copper piping for that and then something on the valve side.

Again, if anyone has experienced this, please help.

Thanks

Its a 3/8 connector, take the tap to a plumbers merchant and dont leave without them.
