I manufacture motorcycle parts using Vintage Connections 8mm and 12mm tubing every day. Great quality. I use the black PVC material.  It does NOT shrink.

Dr. ATV's electrical parts are wonderful, I have a CT90 festooned with bits and pieces from Beatrice, its all good.  The silver PVC on the clone repower bike is over a decade old and still flexible, does not shrink.
