Compression Fittings (pipe too long)

OK, I understand I'm probably answering my own question here, but would like to confirm. I've purchased the correct compression fittings for my new shower, tested them they look to fit both ends, but the straight pipe is too long
I was looking at hacksawing this to shorten it to shape, but looking at the connection for the compression and not fully understanding how they work am I likely to compromise the seal. In the compression end of the seal there appears to be a small "lip", where the olive sits in, does it mould into this on compression or is it sacrificable?
I really don't wanna go and spend lots of moolah on a plumber for a basic thing, but it's looking more and more likely atm. I thought about buying another form of compression adapter that has the same connection but reducing it in length by using some form of copper pipe?
EDIT - Piccies, now added
This is the existing connection on my shower. My new shower has a 15mm inlet pipe, my existing one was 15mm > 23mm BSP

This is what my new adapter looks like against my old one, you can see how far pipe is over

Thanks, although I already understand how to cut copper pipe not that daft, just trying to work out best way of doing it.
Was thinking of something like this
[ | ] - denotes compression fittings - one male/one female
>> - shower inlet
<< - water inlet
== - copper pipe {cut to the lengths I want}
??? - 90 degree pipe>>[|]====[|] ?? <<
That way I could retain some of my existing items, I could use my own 90 degree bend and all I would need would be a small copper pipe (15mm) that I cut to my own length and use use a male/female compression fitting to join the pipe to the 90' bendOwner of andrewhope.co.uk, hate cars and love them

What size cold water feed is the pipe ? if its 15mm as it looks to be all you need is a 15mm compression coupler - short piece of pipe - then the 15mm compression angle, if short and wont reach the inlet then you'll need another short piece of pipe and another compression coupler.
It would however be neater if you could use Yorkshire fittings and solder everything in except for the inlercoupler which has to be compression.You may click thanks if you found my advice useful0 -

Thanks,
I don't even think I need that, looking at it it loosk like I can use just the 90 degree bend on a compression fit and it would connect right up, tempted to try it now to find outOwner of andrewhope.co.uk, hate cars and love them

why not just fit the new fittings the opposite way round?0

was just about to the say the same...turn the fitting around so the other end connects to the shower0 -
You seem for some strange reason to have a 15mm to 1/2 inch 90deg with a 1/2 inch to 15mm adaptor fitted to it. Either turn it round or get a standard 15mm 90deg fitting.0

It look's to me as the copper feed is coming out of the wall at an angle and the plumber cut away part of the shower to fit?
You could do the same but there is a good chance you might damage the shower casing doing it. That way you could use a standard 15mm comp bend. Is that how it is?0 -
Hi All
Thanks for the input I'm having a bit of a dumb day, actually tried out different configurations, but I need to find a large spanner and my water pump pliers as I had problems getting it off today couldn't get a decent griptigeress289 wrote: »It look's to me as the copper feed is coming out of the wall at an angle and the plumber cut away part of the shower to fit?

The shower casing is made by Creda and has a removable corner to make it easier, not sure if the old model didn't
Either way I actually think I can fit it using just a 90' bend or a 90' plus a straight coupler (rotated first)
I'll try it out more when I find the right toolsOwner of andrewhope.co.uk, hate cars and love them
