  • Patent number: 6245183
    Abstract: A multi-layer tube comprises a metal tube having an outer surface and a zinc layer bonded to the metal tube outer surface, wherein the zinc layer is selected from the group consisting of zinc plating, zinc nickel alloys, zinc cobalt alloys, zinc aluminum alloys, and mixtures thereof. A surface treatment layer is bonded to the zinc layer, wherein the surface treatment layer is selected from the group consisting of a zinc/aluminum/rare earth alloy, phosphate, chromate and mixtures thereof. A first polymeric layer is bonded to the surface treatment layer, wherein the first polymeric layer is selected from the group consisting of a thermoplastic elastomer, an ionomer, a nylon, a fluoropolymer, and mixtures thereof. A second polymeric layer is bonded to the first polymeric layer, wherein the second polymeric layer is selected from the group consisting of a nylon, a thermoplastic elastomer, a fluoropolymer, and mixtures thereof.

  • Patent number: 5845837
    Abstract: A polymeric-based material for use in brazing operations to prevent agglomeration and run-off of brazing material on exterior exposed surfaces of the workpiece containing an extrudable melt-processible thermoplastic material selected from the group consisting of polyethylene, polypropylene, ethylene vinyl alcohol, nylon, and mixtures thereof; and up to about 20% by weight, based on the thermoplastic material, of an inert inorganic particulate material such as carbon or carbon black capable of at deposition on and adherence to an underlying metallic surface. In the process of the present invention, the polymeric-based material is imparted by any suitable means to the exterior or exposed surface of the workpiece to be brazed prior to exposure of the workpiece to a suitable fluxing atmosphere and temperature. In tube forming processes, the polymeric-based material is applied to the outer circumferential area of the formed unsealed tubing.

  • Patent number: 5718459
    Abstract: The present invention is a high pressure quick connector especially for use in connecting brake lines of a vehicle. The connector includes a housing which selectively receives a tube retainer cap. Retaining means such as a garter spring or snap ring allow for a low force insertion of the cap into the housing with an very high pull-off force. The cap is used to trap a tube with a bead upset, and the tube may be removed after the cap is unlocked. A second way of releasing the tube includes the use of a tube retainer plug selectively received in the cap, the upset trapped between the plug and cap. The plug can be removed while the cap is still locked in the housing, releasing the tube. A release tool may be used to unlock the cap from the housing. An insertion indicator ring is used to establish the locking of the cap within the housing. A dust boot prevents contaminants from interfering with the operation of the connector.
