摘要： The invention relates to a crimp coupling including a crimping ferrule for connecting a hose to a fitting. The fitting comprises an outwardly projecting stop collar and a groove which extends circumferentially around the fitting at a constant axial distance to the stop collar. The crimping ferrule, which can be slid onto the fitting, comprises a flange, a tapering hinge section, and a cylindrical section. A distance between the stop collar and the groove of the fitting is dimensioned such that the flange, when abutting the stop collar, has a lower edge facing away from the stop collar above the groove. Due to a diameter reduction of the cylindrical section and a tapering hinge section, during crimping, the flange is pivoted such that the lower edge of the flange is turned into the groove by the pivotal movement of the flange.

摘要： A quick connector coupling comprises a collar port having a passage and a collar, a connector to be coupled to the collar port and comprising a tube portion to be received in the passage, a flange on the tube portion, a sealing ring received in a groove on the tube portion, and a locking clip for engaging the collar and an engagement surface of the connector to lock the connector against axial movement. With the connector in a mounted state, the flange has extensions extending along the tube portion beyond the collar, the extensions carry a terminal ring with a surface facing the flange forming the engagement surface spaced from the collar, the clip arranged to lock the connector on the collar port against axial movement, and the groove is axially formed on the tube portion such that the groove is closer to the flange than the engagement surface.

摘要： A flame resistant hose assembly is disclosed. The hose assembly includes a tubular inner layer and a flame resistant layer. The tubular inner layer has interior and exterior radial surfaces and defines a longitudinal axis. The flame resistant layer is disposed about and covers the exterior radial surface of the tubular inner layer. The flame resistant layer is formed from a flame resistant material comprising a polymeric binder and expandable flame resistant composition comprising ammonium polyphosphate. The expandable flame resistant composition is present in the flame resistant layer in an amount of from about 10 to about 60 parts by weight based on 100 parts by weight of said flame resistant material. The flame resistant layer expands when heated to a temperature of about 230° C. or greater and maintains a post-expansion coverage of the exterior radial surface of the tubular inner layer of greater than about 95%.

摘要： A method for making a preformed thermoplastic tube having a tube wall and including at least one bend formed by thermoforming, characterized in that on an inner curve of the bend the tube wall is provided with a pattern of corrugations with minimal dimensions in terms of number of and heights of corrugations such that a wall length reduction resulting from the corrugations along the inner curve is kept at a minimal value necessary to absorb overlength on the inner curve resulting from forming the bend, and in that on an outer curve of the bend the tube wall is smooth and free of corrugations.

A distance between the stop collar and the groove of the fitting is dimensioned such that the flange, when abutting the stop collar, has a lower edge facing away from the stop collar above the groove. Due to a diameter reduction of the cylindrical section and the tapering hinge section, during crimping, the flange is pivoted such that the lower edge of the flange is turned into the groove by the pivotal movement of the flange.
