mused:

i am trying to fit a 8mm microbore to a radiator valve i have the
reducer (Brass ) and it slides on and off the end of the micro bore
pipe even when tighten. how do i fix this so it doesn't slide off

If the reducer is the one that came with the valve then it's most
likely a 10mm reducer. You need to either source a 10x8 reducer and
alter the pipework before it gets to the valve or find a reducer for
the valve that takes it down to 8mm.

If you have already tightened the assembly to a suitable tightness
then the reducer may well be unusable now anyway as it deforms
internally to tighten onto the pipe.

The other reason it might not have worked is that you are a girl and
your weak limbs aren't capable of tightening the thing up properly.
