This is my first attempt at changing a tap :) But I am stuck as to how to connect the hose to my existing pipework. Can you please tell me what part I need

I am trying to fit a new Grohe kitchen tap. The hose appears to be 3/8". The isolation valve is on a 15mm pipe. I hope the photos help.

How do I connect the 3/8 hose to the existing 15mm isolation valve?

It looks like I will still need another metal hose as the Grohe hose is not far enough?

And is this only an issue because I bought the tap from a German eBay seller?

Thank you.

Thank you @muggles . Screwfix isn't far so I'll give that a go. But it seems to me as if only one end of that connector is threaded and the hose and isolating valve in my situation are both threaded.

 
You'll need a nut and olive on top of the existing isolating valves.

You are missing the nuts and olives from the top of your ISO valves. I presume the previous installer just nipped the flexi's straight onto the top of the ISO.

You need 2x15mm nuts and 2 olives.

The finished product. New tap seems to be working well. Thank you all for your help with this! :)


I now want to go and learn how olives work!
 
At the end of installing this tap I had a small white sachet from Grohe with German writing on it. Google Translate tells me the German says "synthetic grease".

Have a missed a step?
 
Not really, you use the grease to lubricate the o-rings that are on the tap end of the flexi tails, just ensures they slot into the hole properly. As long as it's not leaking then I wouldn't worry.

I have a random IV in my plumbing box with an unusual fitting on one side, maybe it is for these new fangled microbore tap cons
