ABSTRACT:
A conduit or other fluid containing structure includes a metal tube having end portions which are exposed for connecting purposes and a liner portion of reduced wall thickness between the end portions. An impregnated braid surrounds the liner portion for rigidifying the same. When the conduit is used as a self-sealing fuel line the thickness of the liner is such that it does not possess enough strength to take on a permanent outward deformation in the presence of the impregnated braid surrounding it, and consequently petalling does not occur. In that application the impregnated braid is surrounded by a sealant capable of swelling when contacted by the fuel, and the sealant is encircled by another impregnated braid to protect and maintain it in place.
