Abstract: A connector system includes a fitting body (104) and a union nut (106). A cutting ring (102) is disposed proximate within the fitting body and union nut. The cutting ring includes a first end (136) engaging with the fitting body and having at least one cutting edge, a second end engaging with the union nut, and a radially extending collar (140) disposed between the first end and the second end. The collar having an annular radial surface facing the first end and an annular groove (144) is defined within the radial surface. A cylindrical outer surface having a first diameter is disposed between the radial surface and the first end, and a transition area is defined from the outer surface towards the radial surface. The transition area being angled radially inward such that the transition area has a second diameter that is less than the first diameter. An elastomeric seal (146) is disposed within the annular groove.

Abstract: A tube connection for connection to a tube includes: a body having a through hole with a central axis, a first end, a second end, and an internal thread arranged close to the first end and coaxial with the central axis. The internal thread has a constant pitch diameter. A maximum diameter of the internal thread increases in an axial direction from the first end towards the second end. A minimum diameter of the internal thread decreases in the axial direction from the first end towards the second end.

Abstract: A crimp connection arrangement for pressurized pipes with a compression sleeve and a pipe, wherein an end piece of the pipe is insertable into the compression sleeve and wherein by an application of an external force to a pressing portion of the compression sleeve, a connection is achievable between the compression sleeve and the end piece of the pipe.

Abstract: A retaining clip for the detachable locking of a plug-in connection arrangement for pressure pipes, male connector of a plug-in connection for pressure pipes with such a retaining clip, as well as a plug-in connection arrangement for pressure pipes with a male connector and a female connector.

Abstract: A crimp connection arrangement for pressurised pipes with a compression sleeve and a pipe, wherein an end piece of the pipe is insertable into the compression sleeve and wherein by an application of an external force to a pressing portion of the compression sleeve, a connection is achievable between the compression sleeve and the end piece of the pipe.

Abstract: A coupling for connecting hydraulic ducts has a female coupling (1) with a receptacle and a first locking face arranged around a longitudinal axis. A male coupling (2) forms a second locking face, arranged around the longitudinal axis. The male coupling (2) can be inserted in the direction of the longitudinal axis (4) through an opening into the receptacle (3). A holding element (9) has a ring (10) with several spring elements projecting from the ring (10). The spring elements (11) extend parallel to the longitudinal axis (4). Locking elements (12) are formed on the free ends of the spring elements (11). The spring elements (11) are, respectively, elastically deformable against a spring force radially out of a locking position into a releasing position. In the inserted condition of the male coupling (2), the first locking face (15) and the second locking (16) face one another.

Abstract: A coupling for connecting hydraulic ducts has a first coupling element (1), in the form of a female coupling, with a receptacle (3) and a first locking face (10), and a second coupling element (2), in the form of a male coupling, The second coupling element (2) has an annular groove (9) that forms a second locking face (27) insertable into the receptacle (3). Several locking elements (10) are arranged in the annular groove (9). The locking elements (10) are held in the annular groove (9) and can be pivoted between a locking position and a releasing position. In the coupled condition of the coupling elements (1, 2), the first locking face (24) is axially supported on the second locking face (25). An unlocking sleeve (28) is displaceable between a locking position and a releasing position on the second coupling element (2). By moving the unlocking sleeve (28) from the locking position into the releasing position, the locking elements (10) are displaced from the locking position into the releasing position.

Abstract: A pipe connection has a connecting member (1). The connecting member (1) has a first end face (4), a first conical bore (5), starting to taper from the latter, which defines a first cone angle (11). The connecting member also includes an axial bore length (9) followed by a bore (6). The outside of the connecting member (1) has a threaded portion (3). A nut (13) has a second conical bore (15) tapered in the direction opposite to the direction of the first conical bore (5). The second conical bore defines a second cone angle (16). A through-bore (17) is in the nut (13). A pipe (18) has a pipe projection (19) which extends into the bore (6) of the connecting member (1). A connecting portion (21) is on the pipe (18). A first conical tensioning face (22) which cooperates with the first conical bore (5) is on the connecting portion (21).
