Abstract: A supply hose includes a core tube, a first layer, a second layer, and a sheath. The core tube defines a hollow interior that surrounds a central axis and is configured to transport fluid therethrough. The first layer and/or the second layer provide tensile strength to the supply line. The first layer is disposed about the core tube and includes a plurality of first fibers. The first fibers are braided about the core tube at a first angle, relative to the central axis. The second layer is disposed directly on the exterior surface of the first layer and includes a plurality of second fibers. The second fibers are braided about the exterior surface of the first layer at a second angle, relative to the central axis. The sheath may be disposed about the second layer.

Abstract: A laminated air brake tubing includes inner and outer nylon layers with an intermediate fiber reinforcing layer. The tubing further includes one and preferably two layers of high density polyethylene positioned adjacent either of said nylon layers with a protective layer separating the fiber reinforcing layer from the high density polyethylene layer. The protective layer is preferably a thin layer of nylon or nylon alloy. Further, the high density polyethylene layer may include compatibilizing agents preventing delamination. The air brake tubing of the present invention meets the current requirements for air brake tubing, however it is less expensive than currently available air brake tubing.

Abstract: A laminated air brake tubing includes inner and outer nylon layers with an intermediate fiber reinforcing layer. The tubing further includes one and preferably two layers of high density polyethylene positioned adjacent either of said nylon layers. The polyethylene layers are cross-linked preferably by irradiation. Further, the high density polyethylene layer may include compatibilizing agents preventing delaminating.
