Tough material in gas ring or stove (9)
I believe the answer is:
grosgrain
'tough material' is the definition.
'grosgrain' can be an answer for 'material' (grosgrain is a kind of material). I'm not sure about the 'tough' bit.
'gas ring or stove' is the wordplay.
'gas ring or' anagrams to 'GROSGRAIN'.
However, I am not sure how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for grosgrain that I've seen before include "silky stuff" , "silk" , "Fabric" , "material" .)
