A hose connecting device has a connector, an inner locking ring, an outer connector and a tubal body. The connector has an insertion section and an engaging section, the engaging section has a size greater than the insertion section, and the engaging section further has a stopping ring at a top end. The inner locking ring is jacketed onto the engaging section of the connector and abutting the stopping ring of the connector. The inner locking ring has an outer threaded section and an abutting portion disposed at a bottom end of the inner locking ring. The outer connector has one of a female connector and a male connector, and a channel, the channel has a positioning step at a middle portion, an inner threaded section disposed below the positioning step of the channel. The tubal body is jacketed onto the insertion section of the connector.

Disclosed is a fluid connection system including a sleeve, a pipe and a fluid connector, the fluid connector including at least one rigid body made from a sterilizable biocompatible material, and the pipe including a flexible connection portion made from a sterilizable biocompatible material that is at least partially elastomeric. The fluid connector and the flexible connection portion of the pipe are assembled to one another, with the flexible connection portion of the pipe surrounding the rigid body, and the sleeve being shrunk tightly, but with free movement, on the pipe.

A pipe connector comprises a first connection, a second connection and a third connection. Longitudinal axes of the connections are located substantially in a first plane. The first connection and the second connection are arranged on a common side in relation to a second plane, wherein the second plane is aligned perpendicular to the first plane and runs through the longitudinal axis of the third connection. The first connection and the second connection are linked by means of a U-shaped pipe section, wherein an elongated pipe section has the third connection being formed out from the U-shaped pipe section. The first connection and the second connection are spaced from one another in such a manner that the first connection and the second connection are accessible for connection of pipe lines by means of a tool, in particular a pressing tool.

Fabrication of formed hoses is provided which include an innermost elastomer layer, a first fiber-reinforcement region, and multiple second fiber-reinforcement regions. The first fiber-reinforcement region has a first fiber-reinforcement density, and is disposed, at least in part, at a bend region of the formed hose, and the multiple second fiber-reinforcement regions have a second fiber-reinforcement density, and are disposed at least at the first and second end regions of the formed hose. The second fiber-reinforcement density is greater than the first fiber-reinforcement density, and results in the first and second ends of the formed hose being less radially-deformable than the bend region of the hose. This facilitates providing a mechanical fluid-tight connection with a hose barb fitting when the formed hose is slid over the hose barb fitting, absent any clamp over the formed hose and hose barb fitting connection.

The present disclosure relates to a hose-line connector, comprising a connection part having at least one elongated hose connection for slipping a hose line onto the at least one hose connection. The hose connection has a sealing segment having a circumferential sealing surface at a free front end and a retaining segment axially adjacent thereto as a clamping region for the circumferential radial clamping of a hose line that is slipped on. On the outer circumference of the retaining segment, the retaining segment has a radially protruding rib structure, which has at least one circumferential rib in the form of an annular ridge and/or at least one longitudinal rib distributed over the circumference and extending axially and/or at an angle to the axial direction.

A pipe joint and a method for using the same are provided. The pipe joint comprises a joint body within which a cavity channel and an outer hole channel are provided, the cavity channel forms a first outer insertion opening for insertion of a flexible pipe and a second outer insertion opening for insertion of a rigid pipe; an inner hole channel is further communicated between the cavity channel and the outer hole channel, which forms an inner insertion opening; an liner pipe is provided in the cavity channel, one end of the liner pipe is inserted into the inner hole channel, and the other end of the liner pipe is provided with a connection section which is provided with at least one bulging part. The pipe joint in the invention improves the connection stability between a flexible pipe and a rigid pipe.

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.

A crimp coupling includes a crimping ferrule for connecting a hose to a fitting. The fitting includes 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, includes 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 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.

A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.
