Stop fighting distiller? (5)

I believe the answer is:

dewar

I'm a little stuck... Click here to teach me more about this clue!

'stop fighting distiller?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?

'stop fighting' is the wordplay.
'stop' becomes 'de' (I am not sure about this - if you are sure you should believe this answer much more).
'fighting' becomes 'war'.
'de'+'war'='DEWAR'

Can you help me to learn more?

(Another definition for dewar that I've seen is " Low-temperature flask".)

I've seen this clue in the Sydney Morning Herald.
