microbore 1/4 inch to 15mm conversion difficulties

[Piper27]

My microbore system is 40 years old and based on 1/4 inch pipe.
I cannot find the special connections to go from 1/4 inch to 10, 12, or 15 mm. And need to for the radiators. I'm told a copper tube expander set is the solution (but they cost about £200). Anyone know of any other solutions??

solder on reducers up to 15mm, or use conex connecters with 8mm reducing rings in

Have you tried 6mm endfeed fittings. The old 1/4" is 6.2mm if I remember correctly.

"Thorite" sell fittings to adapt.
