   More like 100% silicone, as in red high temperature silicone gasket maker
in a tube, stuff.  I consider these to be permanent if not injured, the
black kind can't compare for longevity.
  I changed vitron "O" rings yearly in some water flow sight gages because of 
leaking, I replaced all with silicone and I never had a leak there after.
