Hi Bill



 I was thinking of using JB Weld, is the fire temperature rating for the 

itumescent caulk higher than the 500 degree F. rating for JB Weld?



Thanks,



George in Langley BC

I have the itumescent caulk from the Aviation department at Lowe's.  That was the easy part.

George,

  The firewall sealant should be of a flexible nature, as there is 

significant flexing in this area. I doubt that JB weld would be suitable there.

   Much higher. JB Weld is not rated for effects of a fuel-fed fire.

   It's a filled epoxy not a self protecting putty. You can

   test it yourself for suitability but it's a lot of work.

   I'd recommend you stay with materials designed and tested

   to the task.

Is there firesleeve available to work with the Home Depot 1.5" SS grab

bar for roll-your-own firewall penetrations? If so, what "hose size" do

I look for to equal 1.5" ID or OD? I'm getting the feeling after

bringing home a 1.5" grab bar that I should have ordered the 1.25" stuff

from McMaster-Carr. Even so, I'm still not sure what stock # of

firesleeve will fit this. Any tips? Thanks. I have the itumescent caulk

from the Aviation department at Lowe's. That was the easy part.

Bill,



Check out this website: http://www.racerpartswholesale.com/aero6.htm

Heck, McMaster Carr has it in sizes up to 4" diameter for "standard" 

grade and up to 3" for "aerospace" grade.



See  www.mcmaster.com  , and enter 737 in the search window and it will 

go to page 737 where the sleeve is shown about half way down.



Lots cheaper than www.racerpartswholesale.com, too.

Thanks- that's a good resource.  I have to order my grab bar from them anyway, most likely.
