I have a load of 9mm microbore in my house. It's old stuff I have heard

If anyone knows of a supplier for 9 mm microbore please let me know.

If I were in that position I might mandrel & hammer it out to 10mm.

I presume the OP means pre-metric 3/8 inch microbore which is what I've
got. When I had to have a couple of TRVs and lockshield valves replaced
my heating chap used 10mm fittings with extra solder and we haven't had
any leaks (touch wood).
