Trying to install a tap in my kitchen I'm a complete DIY Novice, I've cut the copper pipes and fitted isolation valves on.

The tap tails I got with the tap are 400mm in length which are way too big, smallest I can find is 300mm so I went and got them but then realised I couldn't fit them onto the isolation valves :oops:

What would I need to connect them? Worse case I can use the bigger tails for now

These are the tap tails that came with the taps

Here's the new ones

You need a short length of copper pipe, and another nut & olive which presumably came with the isolation valve when you bought it

Ive spare copper pipe but I don't really want to add anymore after the isolation valve as I'll struggle to get the tap to slot in.

Tbh I wished they did 100mm flexible tap tails
 
Before you go much further, bear in mind those flexi's need to be fitted correctly, trying to cram too long a flexi in, with the result it is twisted, kinked, knotted or under any strain, will probably result in premature failure, and a flood. If the copper supplies are too long, cut them back to suit.
 
So is there a way to connect it to the isolation valve I've found these in the garage.

Of course it depends on the flexie end type as well
 
If it's a normal tap tail flexi pipe with a female end fitting to the ISO then use a flat file and file the end of the ISO valve so the edge doesn't bite the rubber washer, they're brass so they file flat easily.

If the flexi's are too long then pig tail them so it effectively shortens the length without stressing the pipe.

You can see the amount of room I've got to play with. I'm just using the old 400mm tap tails which don't look great.

If this doesn't work I'm not sure what to do as the cold feed is still too high
