Seals

Inlet Seals & Joints

Flexfab APU inlet seals and joints are used to create seals around pipes and other penetration points through the bulkhead. Flexfab APU components allow the penetrating media to have minimal X/Y/Z movement while maintaining a fireproof and pressurized seal between compartments.


Fuel Shrouds

Flexfab high-temperature lightweight fuel shrouds are a secondary containment system designed to route the inadvertent leaking of fuel from the nozzle array to a safe location. Fuel shrouds mount around the fuel line and nozzle array on the engine and can be taken on and off the engine without disconnecting the fuel delivery system.
