Probably, but . . . .

The first one will use a soft rubber washer for sealing and is intended to seal against a flat face.

The second (compression fitting) seals on an internal tapered face so there's no need for the outer face to be flat, it will likely be V shaped and may be sharp or uneven.

If the face of the on the compression is not too sharp and uneven, you don't overtighten the quick release coupling and the working pressure isn't too high then it should work fine.

If you find the end of the compression fitting too rough then you could lightly file it flat with a fine file, make sure it is very smooth and flat, possibly lap it on a sheet of wet & dry on a flat surface.

Yup should be fine. Much the same as fitting flex tap tails to the end of a service valve. If you can't get a decent seal on the end of the valve (unlikely IME), then you can always get a seal on the thread using PTFE or fernox LS-X

Very likely - though not guaranteed. Whilst most 15mm compression fittings use 1/2"BSP threads, some use a finer thread - so the nipple may not screw on.

Assuming that it *does* screw on, you will - as others have said - need to find a way of sealing it, since these parts are not *intended* to fit together. I would be inclined to use liquid PTFE on the threads.

Thanks for the help chaps!
