Using pneumatic tubing for other uses? ex: power transmission

Is it against the rules to use the legal pneumatic tubing for alternative uses? Such as making a belt for a pulley system or to push/pull/rotate or otherwise transfer force?

I’m new to mentoring Vex teams and couldn’t find an answer or figure out who/where to ask. Thanks.


I think this is legal-have seen teams in my area use it for intakes and such
