I cut my own using a razor blade.  I use 7/16"OD X  1/4" ID.  SOFT Silicone tubing, food Grade.  The only color I have been able to find that works for me is translucent (white-ish color).  It helps to get the posts wet so they slip on.  It can be a tight fit on the round end posts; you can buy 1/2"OD tubing it's too much trouble.  Clean up any drops with a clean towel.    Be careful not to scratch or gouge the posts when you take the old insulators off BTW.  I'd test 3-4 bars and see if it's what you want.    Seems like some orders are softer than others, softer is better.   

I stared using silicone because some of the 'store bought' insulators would squeak when I pressed the damper up and down.
