- AS Flightlines has our own proprietary marked firesleeve.  If it says AS Flightlines
        on the side, you can be assured the assembly meets our specifications.  (Effective
        1-2018)
- Our firesleeved hose ends are sealed with high temperature sealant to protect against
        breach of the firesleeve during a firewall forward fire.
- Our firesleeve is very tightly conforming to the hose.  It is more difficult to build
        assemblies with smaller diameter firesleeve.  However, this produces a lighter, better
        looking and more flexible assembly.
- Firesleeve is recommended on ALL hoses firewall forward.
