Abstract: A quick-disconnect hose adapted to be coupled with a cylindrical male fitting having an outer annular bead. The hose comprises a flexible tubular wall with a female coupling element at an end region of the wall adapted to be received over the male fitting. The coupling element comprises an inner ply lining the wall at the end region, an outer ply girdling the wall at the end region, and hoop structure interposed between the wall at the end region and one of the inner and outer plies. The inner ply is formed with an annular groove adapted to receive the annular bead of a male fitting in coupling relation therewithin. The hoop structure is disposed axially outwardly of the annular groove and resists axial passasge of the annular bead of the male fitting to and from the coupling relation within the groove.

Abstract: An article of protecting high pressure hydraulic lines, fuel lines and the like is disclosed. The article includes a silicone polymer coated and impregnated glass fiber woven sheet. The sheet is self-coiling and normally assumes the configuration of a coiled, generally cylindrical sleeve. The woven glass fiber sheet is cut along a full bias so as to increase the flexibility of the normally coiled sheet when installed on the line to permit the sleeve and protected line to assume curved configurations without buckling or separation of the sleeve. The sheet is uncoiled and snapped around the high pressure line and a high temperature silicone adhesive seals an elongated, longitudinal seam defined by the overlap of the lateral edges of the sheet.
