14mm to 15mm copper

I am relocating some gas cylinders on a RPH and the existing pipe has a external diameter of aprox 13.5-14mm, I need to connect on to it with 15mm,

Any suggestions? Thanks

Will the smaller pipe fit in the 15mm if so you can solder it
8mm oil line fits inside 10mm oil line done it lots and its grand

It will fit inside gray, however is this an acceptable jointing method for gas?

If it's a snug fit it's only same as forming your own joint

you could try an expander

The customer only wants the bottles relocated. I think i've cracked it now, the existing pipe should fit sung into the internal part of a street elbow.. according to micrometer measurement. that should make a nice soldered joint.
