trap pedal build question

Hello all!

I am building a pedal for my trap using most of the parts out of the shop. I have been trying to figure out what to use for the black compression thing under the vector pedal. Anyone have any recommendations? Thanks!!!

Mcmaster carr sells black ribbed tubing that many people use for the trap bellows. A quick search for trap bellows here should give you some pics and part number for it.

Thanks bro! You have been a wealth of help!!
