摘要： An end-form fitting includes a tube and an auxiliary component disposed around the tube. One of the tube and the auxiliary component is deformed to cause the auxiliary component to engage the tube in order to militate against relative movement between the tube and the auxiliary component. The auxiliary component includes an array of surface irregularities formed therein and configured to engage an outer circumferential surface of the tube to form a corrugated joint therebetween. The auxiliary component is formed to include a radially outwardly extending orientation structure for establishing a rotational orientation of the end-form fitting when being coupled to a complimentary end-form fitting.

摘要： A full flow hose fitting includes a fitting end, having an elongated stem with a barbed external surface and a retaining collar, having a barbed internal surface. An internal diameter of the elongated stem approximates an internal diameter of a hose to be attached to the fitting. An inner diameter of the retaining collar is larger than an outer diameter of the elongated stem, defining a retention space to secure an end of the hose when it is disposed between the elongated stem and the retaining collar. The fitting is formed from an assembly process that pushes fittings into the end of the hose rather than using an internal or external crimped ferrule to secure them.

摘要： A press fitting for a pipe connection is provided. The press fitting comprises a fitting body for connecting the press fitting to a pipe, a substantially cylindrical pressing sleeve fixed to the fitting body and having a pressing area, and a stop ring fixed to the pressing sleeve and limiting the pressing area in an axial direction of the press sleeve. The stop ring has a substantially cylindrical inner contour with protruding first regions and second regions receding from the first regions. The first areas of the first stop ring encompass an outer contour of the pressing sleeve in a clamping manner. The second areas of the stop ring are spaced from the outer contour of the pressing sleeve.

摘要： A flexible duct includes a hollow tube shape, at least one end, a first circumferential attachment and a second circumferential attachment integral to the at least one end, wherein the first circumferential attachment and the second circumferential attachment are each configured to independently mechanically couple the at least one end around a first inlet or a first outlet, and wherein the first circumferential attachment and the second circumferential attachment are different. A method includes providing a flexible duct, selecting one of the first circumferential attachment or second circumferential attachment of the flexible duct, and mechanically coupling the selected first circumferential attachment or second circumferential attachment around the first inlet or first outlet. A connector for a flexible duct includes a hollow tube shape extending between a first connector end and a second connector end and a first circumferential attachment and second circumferential attachment integral to the at least one end.

摘要： A hose clamp developed for hose structures used in many fields particularly in the automotive sector. The hose clamp includes a clamp band which surrounds the hose, a clamp housing which engages both ends of said clamp band, at least one positioner clip which limits radial and axial motion of the hose clamp on the hose, a wing with springy feature which is located on the positioner clip and allows diameter reduction of the hose clamp, a structure which couples the positioner clip to the hose by a plurality of serrations and does damage the hose.

摘要： A mounting group for a press fitting is provided. The mounting group includes cylindrical pressing sleeve with a pressing area and a stop ring fixed to a first axial end of the pressing sleeve and limiting the pressing area in an axial direction of the pressing sleeve. The stop ring has a first inner contour on a side opposite the pressing area and as a first circular segment and a second circular segment, which extends over a smaller part of the first inner contour than the first circular segment. The stop ring has a constant cross-section in the region of the first circular segment and an element arranged in the region of the second circular segment which projects inwardly beyond the constant cross-section of the first circular segment and causes a tilting of an axis of symmetry of the pressing sleeve.

摘要： A hose and rigid pipe connecting system used in a high pressure system comprises: a hose made up of connecting a core pipe and a corrugated pipe, the outer side of the corrugated pipe being wound and woven by metal wires; a rigid pipe; a transition joint connecting the hose and the rigid pipe; and a retaining ring buckled on the outer side of the hose and the transition joint. The invention has the advantages that the sealing performance between the hose and the rigid pipe can be greatly improved, and the problem that the connecting part of the hose and the rigid pipe can not bear pressure Or resist high and low temperatures is solved; besides, the axial tensile strength and sealing reliability are improved by winding and weaving metal wires on the outer side of the metal corrugated pipe and then welding with the core pipe.
