This would be for a sealant between a sleeve and a pipe carrying gas.
I notice that the IGEM procedures use the term "mastic seal" as an example but the description "mastic" is very vague.
Can anyone provide what sealant the trade use?
What sealants conform to "flexible fire resistant compound"?

It says fire retardant in the headline, but it does claim to have fire resistance.
What do plumbers really use?
Plumba Flue Is widely for this job.
Note that a seal is only used on the the interior sleeve in a building.
The exterior of the sleeve is left open
Many thanks. I see it can only stand 300 degs C but if that is what is used............
I was aware of that, but this is for an internal wall. I had presumed best practice would be to seal the end with the smallest volume of space.
