Senior Aerospace welded metal bellows firewall feedthroughs are used to seal penetrations while still allowing for axial motion. The all metal construction allows for operation in extreme temperature environments where conventional feedthroughs will fail.

These feedthroughs use a welded metal bellows to provide a hermetic, dynamic seal allowing for a zero leakage penetration through an engine firewall. The all metal construction is suitable for extreme operating temperatures (800+°F Operating, 2000°F Fire Test) and is corrosion resistant. The bellows allows for long stroke.
