If a fire starts in an airplane engine, critical hose assemblies — such as those used in a plane’s cable, electrical, fuel, hydraulic, and electric systems — must be protected against fire. Otherwise, a risky situation could get a whole lot worse.
The solution is fireproof and fire-resistant hose lines called fire sleeves. Per the FAA, fireproof hose lines “must withstand a 2000°F flame (+15O’F) for 15 minutes minimum while still fulfilling its design purpose.” Fire-resistant components are required to last 5 minutes under the same conditions.
Drawing on our experience of engineering abrasion and fire resistant products, SEPCO works closely with aerospace clients to design and manufacture multiple custom solutions such as bulk head seals, specialty grommits, sealing rings for de-icing systems, and Pyrosleeve® firesleeve for hoses and cables.
Working closely with aerospace clients to optimize our Pyrosleeve product, we’ve also had the opportunity to develop multiple custom bulkhead seals, specialty grommets, and sealing rings for deicing systems.
Our Pyrosleeve® firesleeve conforms to SAE AS1072 standards allowing hose assemblies to meet SAE AS1055 requirements which include a 2000° flame test.
