A method for treating a pipe, in particular a motor vehicle pipe, wherein a flare is generated at least at one pipe end of the pipe. At least areas of the flare are provided with at least one layer, which changes the friction properties of the coated surface of the flare. The flare is coated by means of plasma coating.

Method for treating a pipe, pipe and pipe connection device

The invention relates to a screw element for the connection of tubes, preferably motor vehicle lines. A threading and at least one contact surface without threading are provided on the screw element. The screw element has an outer coating and an inner coating. The outer coating comprises a first polymer and nanoparticles of a first solid material. The inner coating may also comprise nonoparticles or a polymer.

Screw element for the connection of tubes and tube connection device having this screw element

A screw connection device for connecting two pipes with flared ends, comprises a screw, a nut and a spacer. The nut has a front end aperture from which an accommodating space extends to a rear end aperture in a rear end wall. A surface of the nut in the accommodating space has a threaded section which extends toward the rear end wall which has a flange face in the accommodating space. In a pre-installed state, the spacer and a first pipe end with a first flare are accommodated in the nut, such that the spacer is held undetachable between the first flare and the internal thread. A second pipe end with a second flare can be held in the accommodating space by the screw, threaded into the nut such that the second flare is pressed against a sealing surface of the spacer and the spacer is pressed with a further sealing surface against the first flare.

Screw connection device for connecting the flared ends of two pipes

A screw connection device for fluid lines having a coupling nut with an interior space and having an internal threading running over the circumference of the interior space, as well as having a connecting element with an external threading. A line end of a fluid line is accommodated in the coupling nut, wherein the line end exhibits an end shape. When the internal threading of the coupling nut is screwed to the external threading of the connecting element, a locating surface disposed in the interior space of the coupling nut is moved toward the back end of the end shape, or vice versa, respectively. A spring element is disposed between the locating surface and the back end of the end shape, running over the circumference of the fluid line.

Screw connection device for fluid lines, in particular for motor vehicle fluid lines

A screw connection device for connecting two pipes, comprising two pipes with flanged pipe ends, a screw, a nut, and a spacer, wherein the nut includes a receiving space, wherein the spacer is securely received in the receiving space. The spacer retains the first pipe securely in the nut, wherein the second pipe is retained in the screw and can be fastened in the nut by means of the screw. An exterior surface of the spacer has at least one cylindrical section, wherein the spacer has a first end surface and a second end surface. A first projection is provided on the spacer, which engages with the nut in the region of the receiving space such that it is securely accommodated therein. The nut includes an exterior surface with flat sub-surfaces. At least one flat sub-surface includes an indentation to form a detent in the retaining space to secure the spacer in the nut. In one form the exterior of the nut has six flat sub-surfaces and every other flat sub-surface has a detent.
