You may well have a hand in it, albeit briefly (6)
I believe the answer is:
sleeve
'hand in it albeit briefly' is the definition.
I know that 'hand' relates to this answer.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for sleeve that I've seen before include "Cover for arm and vinyl record" , "Covering for arm or record" , "Part of a shirt or jacket" , "Record-holder" , "Container for LP" .)
