They are 3/8th UNF x 24 tpi, the male ones are long and the pipe is 3/16" and not 6mm.
You should consider Kunifer (cupro nickle) pipe and brass fittings instead of copper and steel fittings. I don't like copper as it work hardens and fractures. Copper is OK if it is properly supported but if there is any movement at all then there could be problems. The sliding cylinder on the rear brakes of Morris Minors is a prime example of where NOT to use copper pipes as are the long unsupported pipes from the master cylinder of Vivas. However, the short pipes you are looking for probably will be OK in copper but consider Kunifer as a first preference.
If I had the fittings and pipe I could make you a pair.
