Dow Corning used to make a high temp Silicone RTV (Silastic RTV TM) that matched the red in that rubber sheet.  Don't know if it's still available.
At any rate a number of amp companies build chimneys just as listed below.

BTW DC has been absorbed by Dow,

No sense paying exorbitant prices for stuff you can make yourself cheap. You
can purchase the material to make your own from McMaster-Carr at

Here at the items you need:

High-Temperature Silicone Rubber Sheet
4" Wide, 1/8" Thick                           2614T45                         

Loctite Silicone Sealant, 2.7 oz.. Tube, Clear

If you need taller chimneys, you can purchase wider silicon sheeting for a few
dollars more.
