How to remove compression reducers

[600rob]

Ive got a few rad valves with bodies for 15mm pipe work that have been fitted to 10mm pipe.

Im assuming they have been fitted using these compression reducers

when i come to replace the valves, how easy is it to remove the reducers?

can they be twisted off or will they need to be carefully cut off in a similar way to how you would cut off an old olive with a hacksaw?

Pipe is usually mullered and needs cutting back. But you'll need a hacksaw.

... or a 10mm pipeslice

just replace the valves with 15mm ones and leave the reducers there
