ABSTRACT:
A flammable fluid carrying tube has one of its ends disposed within a tube coupling which is adjacent a hot surface of the gas turbine engine. A flammable fluid deflector is disposed between the coupling and the hot surface for deflecting, away from the hot surface, any fluid which may leak from the coupling. The deflector includes an axially extending portion disposed against the tube outer surface adjacent the coupling, the axially extending portion including a circumferentially extending tab which fits into a corresponding slot in an arcuate positioning sleeve which is bonded to that surface of the tube facing away from the hot engine surface and which positions the deflector axially and circumferentially. A standard clamp secures the deflector to the tube. The deflector may be used with virtually any standard coupling and replaces expensive concentric tube designs which utilize special couplings and dual seals for redundancy.
