A connection system (1) is for distributing water in a domestic system. The connection system includes a flexible pipe (2) having at least one end portion for connection to a hydraulic connector. At least one hollow insert (3, 6) axially engages the end portion of the flexible pipe (2). The insert (3, 6) includes a flange-shaped head portion (31, 61) which abuts against the free end of the end portion of the pipe (2). A reinforcement portion (32, 62) extends from the head portion (31, 61) into the end portion of the pipe (2). At least one annular bushing (4) mechanically clamps onto the end portion of the pipe (2). At least one connecting element (5) is fitted onto the end portion of the pipe (2) and includes a device for connection to the hydraulic connector.

An eccentric universal joint mechanism, even when there is a lateral displacement between a first pipe and a second pipe, can absorb the displacement and connect the first pipe and the second pipe. The eccentric universal joint mechanism includes: a first sleeve; a second sleeve; and an eccentric universal joint connecting the first sleeve and the second sleeve. The eccentric universal joint includes a first eccentric pipe, and a second eccentric pipe rotatably joined to the first eccentric pipe. A displacement between the center line of the first eccentric pipe and the center line of the second eccentric pipe is determined by the rotational position of the second eccentric pipe.

In one aspect, an unloaded annular flexible seal is provided to receive an end of a conduit and to provide a seal between the conduit and a flange of a machine. The seal has a base having an inner surface, an upper surface, an outer surface, and a lower surface, and a leg having an inner surface, an upper surface extending from the inner surface of the base, an outer surface extending from the lower surface of the base, and a lower surface. A surface area of the outer surface of the leg is greater than a surface area of the lower surface of the leg. In another aspect, the seal is included in a seal assembly that also includes an annular back-up member having an L-shaped cross section, including a back-up member base and a back-up member leg configured to sit in the groove of the flexible seal.

A wastewater tank arrangement for an aircraft, including a wastewater tank and a drain pipe having a first end and an opposite second end, the drain pipe fastened with its first end to the wastewater tank and having a second end for connection to a service panel in the aircraft structure. Providing a wastewater tank arrangement can effectively compensate tolerances between the wastewater tank and the service panel, and can effectively compensate installation and manufacturing tolerances during the course of the initial installation, in that the wastewater tank arrangement has a tolerance compensation device configured to connect the second end of the drain pipe to the service panel and compensate tolerances between the second end of the drain pipe and the service panel.
