A hydraulic braking system connector comprises a first coupling terminal having an annular abutment surface, a coupling sleeve having a first axially outer annular portion, receiving the first coupling terminal, an annular wall with a first annular abutment surface to abut the first coupling terminal abutment, and a second axially outer annular portion, to be coupled with a component of the hydraulic braking system. A first annular locking element is axially moveable between a rest position and a locking position. A first annular hydraulic sealing element is configured to be activated by the first annular locking element when in the locking position. The annular abutment surface of the first coupling terminal is in abutment on the first annular abutment surface of the coupling sleeve when the first annular locking element is in the rest position.

A brake pipe fitting tool includes a first hydraulic pipe wrench, a second hydraulic pipe wrench, a connecting portion and a handle portion. The first hydraulic pipe wrench has a first jaw defining a first hydraulic pipe insertion opening. The second hydraulic pipe wrench has a second jaw defining a second hydraulic pipe insertion opening. The connecting portion connects the first hydraulic pipe wrench to the second hydraulic pipe wrench such that the first hydraulic pipe wrench and the second hydraulic pipe wrench are fixedly and rigidly connected to one another and spaced apart from one another by a predetermined distance. The first hydraulic pipe insertion opening and the second hydraulic pipe insertion opening are parallel to one another and aligned with one another. The handle portion is rigidly fixed to one of the first hydraulic pipe wrench, the second hydraulic pipe wrench or the connecting portion.

A bracket for mounting an anti-lock braking system sensor to a vehicle axle adjacent to a tone ring. The bracket includes a tubular body portion with a surface defining an opening for receiving the anti-lock braking system sensor. A pair of legs, each extending from the body portion. A pair of feet, each define an end portion of a respective one of the pair of legs. Each of the pair of feet is adapted for attachment to an exterior surface of the vehicle axle. The body portion, the pair of legs and the pair of feet are integrally formed as one-piece from powdered metal.

Air brake tubing is provided having an air brake tube body comprising at least one layer formed from a composition comprising a copolyester, polyethylene terephthalate or polybutylene terephthalate; and a thermoplastic polyurethane.

A utility vehicle control device for a parking brake device of a trailer vehicle includes a pneumatic supply connection, a control connection for controlling a spring brake cylinder, a directly manually actuatable parking valve, a first connection line and a control valve for controlling the parking valve. The parking valve is arranged in the first connection line, and wherein as a result of the parking valve, the supply connection and the control connection can be connected via the first connection line. A control line branches from the first connection line. The control line is connected to a first pneumatic control input of the control valve, wherein the control valve has a second pneumatic control input. In the event of an unexpected reduction in operating pressure in the first connection line and/or in the control line, the control valve can be controlled by the first or second control input of the control valve such that a switching state of the parking valve can be pneumatically controlled by the control valve independently of an operating state of the supply connection, whereby the control connection is ventilated by the parking valve.

A coupling arrangement for a hydraulic device, in particular for a brake hose of a hydraulic brake of a vehicle. The coupling arrangement includes first and second coupling components, and the first and second coupling components can be transferred from an uncoupled state into a coupled state. The first coupling component has a hydraulic chamber which is prefilled with a first hydraulic liquid, and the second coupling component has a hydraulic cylinder which is prefilled with a second hydraulic liquid. The hydraulic chamber and the hydraulic cylinder are fluidically connected to one another in the coupled, a first flow opening is incorporated in the hydraulic chamber, and the first coupling component has a first sealing device which closes the first flow opening in a flow-tight manner in the uncoupled state and frees it in the coupled state.
