Fitting a tap

[rsbmw]

Want to swap the kitchen tap with a "Grohe" - I understand these come with tails to connect to 3/8" pipework rather than UK 15mm. I understand I can buy reducers, but given the pic below of existing setup, is there anything I can buy that would prevent me having to remove the brass coupler that's already attached to the pipework? Different tails or whatever. Ideally I will just be able to attach fitting to new Grohe tail (or swap those out) and then screw it onto the existing pipework. Reduces the chances I can balls it up (I hate plumbing).

Thanks, had seen both of those things but I don't have a great track record of replacing plumbing joints and having them not leak. I think I'm 0-3 on that front, hence wanting a screw on solution

Whilst I appreciate a good ridiculing, I'm still interested to find out if a product exists that does what I want. Seems a 15mm nut on one end, and 12mm external thread on the other wouldn't be that difficult.

Thanks, we'll see if I can claw one back on the scoresheet.

Question - Can I leave the existing nut + olive on the pipe and use with the new compression fitting, or do I need to trim that off. Easier said than done on one of the pipes!

Hooray, I managed to do plumbing and there are no leaks! (yet)
