Abstract: A central body for a hydraulic system for fluid, including a frame having a first tubular end for connecting an upstream hydraulic circuit including a first fitting, and a second tubular end for connecting a downstream hydraulic circuit including a second fitting, the central body including a passage passing through the frame in order to convey the fluid coming from the upstream hydraulic circuit to the downstream hydraulic circuit, the frame being produced from an electrically insulating material, the central body including a printed circuit having controlled electrical properties in order to conduct a part of the electrical charges flowing in the upstream hydraulic circuit and the downstream hydraulic circuit.

Abstract: A pipe connection accessory 1 comprising a sleeve 4 designed to be crimped onto one end of a pipe tube and designed to engage at least indirectly with another pipe element, is characterized in that that surface 4A of the sleeve which is intended to come into crimped contact with the end of the tube comprises an adhesive-coated portion 10 comprising an adhesive made up of at least two components, one of which is encapsulated. This adhesive-coated portion is advantageously set back, preferably with projecting collars.

Abstract: A device for coupling fluid-circulation tubes includes a first coupling connecting first and second tubes, in which first coupling the respective ends of the first and second tubes are arranged coaxially aligned with one another. At least one of the opposite ends of the first and second tubes is capable of being secured to a second coupling, which is configured to couple the first or second tube to a pipe of a fluid circuit, the second coupling including at least one portion made in one piece with the opposite end of the tube in question, such that the portion of the second coupling forms the opposite end of the tube in question.

Abstract: A crimping connection comprising an unthreaded sleeve having a tail section joined to a head section. The tail section includes a malleable portion which is adapted to be crimped onto the outer periphery of a pipe and the head section includes a portion of higher hardness than the malleable portion which is adapted to be removably attached within a pipe.
