Possible clue to a Vader OT Reveal part?

[Darthmagpie]

I am not sure if anyone has gone down this road before but my searches didn't show anything. Better to be safe than sorry. Any thoughts?

The part I am refering to:

They are Vynal insulated bullit connectors for wires.

Thanks Wackychimp

The parts look to be metal to me not really good as an insulator.

they are alu parts.
and a little too big for such an insulator.

Did you find other parts allready.
im looking for the famous grey hose.
