Abstract: A pipe connection includes a connection body, a nut which can be screwed onto or into the latter and which has a conical bore which widens toward the connection body, and a pipe guided through a bore in the nut and having an outwardly projecting formation with two clamping faces. A first clamping face is parallel to the end face of the connection body and is supported on the connection body at least in certain regions when the pipe connection is in the clamped state, and the second clamping face is cone-shaped in a manner corresponding to the conical bore in the nut and is supported in the conical bore in the nut. The connection body has a radially encircling cutout by which a receiving space is formed for a sealing ring that is delimited by the first clamping face and has a polygonal, symmetrical cross section.

Abstract: An apparatus for fastening lines, in particular power cables, pipes or hoses, includes at least two interconnectible fastening parts which form a feedthrough when assembled. The fastening parts include two clamp parts which are hinged together via at least one hinge and which each receive at least one clamping block having a groove in its outer lateral surface, in which groove a portion of a clamp part is positioned, and which clamping block has, on its inner face opposite the groove, a channel, which has the shape of a cylinder-barrel portion and extends axially at a right angle to the groove, for receiving a line. A fastener is arranged at the end of a clamp part opposite the hinged connection, the fastener hook of which fastener can be brought into engagement with a mating fastener hook arranged at the end of the other clamp part opposite the hinged connection.

Abstract: A coupling part for a hose coupling, in particular for high-pressure hydraulic lines, and a hose coupling having such coupling part, has a connection head for connecting to a fitting, and, formed on the connection head, a press-fit nipple, which is intended for accommodating a hose-end portion, on which a pushed-on hose-end portion can be fastened in a sealing manner by pressing action by an at least partially sleeve-form press-fit ferrule enclosing the hose-end portion, and which has a rib profile including ribs bounded by grooves. The rib profile has at least two profile portions. The grooves of the first profile portion, which is directed towards the connection head, have a symmetrical cross section and the grooves of the second profile portion have an asymmetrical cross section and a larger groove volume than the grooves of the first profile portion.

Abstract: A cutting ring fitting for a thin-walled pipe, includes: a connecting body having a tapered cone; a cutting ring; a union nut which can be screwed onto the connecting body; and a reinforcing sleeve for insertion into the pipe, the reinforcing sleeve having an axial slot. A pipe includes such a cutting ring fitting, and a method mounts such a cutting ring fitting on a thin-walled pipe.

Abstract: A device for fastening hoses includes two fastening parts which can be connected to one another and which, in the assembled state, form a passage having an elliptical, in particular circular cross-section, wherein at least one radially encircling groove having an in particular edge-free cross-section is arranged in the inner lateral surface of the passage.

Abstract: A connection arrangement for connecting a metallic pipeline has a screw connection body having a pipe holder for the pipeline, a union nut that can be screwed onto the screw connection body and a cutting ring disposed between the screw connection body and the union nut. The cutting ring has an outer cone that interacts with an inner cone of the pipe holder of the screw connection body. The cutting ring has an essentially radial contact surface, subsequent to the outer cone, which surface limits tightening against a face surface of the screw connection body. An elastomer circumferential seal is disposed in a ring groove in the region of the outer cone of the cutting ring. The ring groove, which accommodates the elastomer circumferential seal, is disposed in the outer cone of the cutting ring, at a distance from its contact surface and, wherein a ring surface is formed between the ring groove and the contact surface.

Abstract: A device for fixing components, particularly pipes or tubes, includes two fixing parts with recesses, which can be connected to each other, the parts forming a bushing in the mounted state, the inner contour thereof being designed to receive a pipe or a tube, at least one sacrificial element being arranged for minimizing corrosion, particularly crevice corrosion, in the event of a respectively received component being increasingly consumed with the onset of corrosion and reduction of the service life of the fixation. At least one fixing part includes at least one recess which opens up into the inner contour of the bushing and in which at least one sacrificial element is movably arranged, the sacrificial element being pre-stressed in the direction of the bushing by a spring element.

Abstract: The invention relates to a connection arrangement for connecting a pipeline, in particular a metallic pipeline, the arrangement having a screw connection body having a pipe holder for the pipeline, a union nut that can be screwed onto the screw connection body, as well as a cutting ring disposed between the screw connection body and the union nut, wherein the cutting ring has an outer cone that interacts with an inner cone of the pipe holder of the screw connection body in such a manner that it is deformed radially inward in some regions when the union nut is tightened, and cuts into the material of the pipeline with at least one cutting edge, with a notching effect, with shape fit, and wherein the cutting ring has an essentially radial contact surface, subsequent to the outer cone, which surface limits tightening against a face surface of the screw connection body, and wherein an elastomer circumferential seal is disposed in a ring groove in the region of the outer cone of the cutting ring, for contact insid

Abstract: An arrangement for fixing a clamp to a C-shaped rail comprises a fixing plate urged against inner arms of the rail by a compression spring, the plate having a width which fits between inner arms so that it can be inserted from above, and a length, which fits between the arms of the C-shape, diagonally opposite portions of the ends of the plate being shaped to permit it to rotate between the arms of the rail. The spring is located between the head of a spigot fixed to the fixing plate and a supporting plate. The ends of inner arms are arranged to be located in grooves in the fixing plate.
