A microfluidic group includes a female connector and a male needle connector. The female connector has a connector chamber in a containment body; a duct extending in the containment body to a duct opening on a first face of the connector chamber; a needle entry hole extending from a lateral face of the containment body to a second face, not facing the first face of the connector chamber; and a gasket arranged in the connector chamber. The gasket has a side wall internally delimiting a cavity and extending in part adjacent to the second face of the connector chamber. The cavity of the gasket faces the first face of the connector chamber.

A pipe connector includes a housing body defining an axial bore arranged to receive a pipe section having an end and extending between a housing top and a housing bottom. A sealing member is seated in the axial bore with a conical inner surface configured to interface with the end of the pipe section. A cap member with an opening is threadedly attachable to the housing top. A locking member is carried in the cap member and configured such that the pipe section is only movable through the locking member in a direction toward the sealing member. The locking member drives the pipe section downward along the conical inner surface and creates a fluid tight seal between the sealing member and the pipe section when the cap member is threaded down on the housing top with the end of pipe section engaging the conical inner surface of the sealing member.

A pipe coupling comprising a housing with a receiving space for a pipe section, with fixing members for releasably fixing the pipe section in the housing, and a sealing element which is arranged in the receiving space and is designed to surround the free end of the pipe section received in the receiving space on the outer circumferential side and thereby seal the interface between the housing and the pipe section in a fluid-tight manner. The pipe coupling is characterized in that the sealing element is designed in the form of a sleeve with a first and a second free end, in that a bulge is provided at the first free end, and in that a tubular section protrudes from the bulge and forms the second free end on the edge side.

A connector for connecting to tubes, in particular to the cooling plate tubes, including a body having a first tubular portion and a flange on the outer circumference and at one end of the first tubular portion. The connector includes two circular or tubular seals which are spaced apart and arranged on an inner peripheral surface of the first tubular portion, in which, the connector includes a leakage channel formed between a leakage opening and the flange, the leakage opening being disposed between the seals.

A block fitting assembly comprises a first block having a first fastener aperture formed therethrough, a second block having a second fastener aperture formed therethrough in axial alignment with the first fastener aperture, and a fastener extending through the first fastener aperture and the second fastener aperture to couple the first block to the second block. The block fitting assembly includes a thermal expansion compliancy feature in the form of at least one of an inner surface of the second block defining the second fastener aperture including an axially extending non-threaded portion adjacent a threaded portion thereof or the fastener including a necked portion having a smaller outer diameter than a minor thread diameter of a threaded portion of the fastener.
