Technical name for vexlabs "rubber links"

[AdamHeard]

I'm trying to find larger sizes of what vexlabs calls "rubber links". I've seen them before, I just can't find them because I don't know the technical name.

I'm looking for something in the 3/8-1/2 diamter. Coarse or Fine thread are fine.

Thanks,
Adam
