A coupling assembly for releasably interconnecting fluid passages comprises male and female coupling members, which are mated by inserting a probe and socket of the members respectively. Each coupling member has a first end arranged for connection to a fluid passage. When mated in use, the coupling assembly provides a straight fluid conduit between the fluid passages comprising through-bores in each of the coupling members coincident along a first longitudinal axis. When mated in use, the probe and socket are arranged coincident on a second longitudinal axis, which is inclined to the first axis. Sealing means comprising an annular sealing ring proximate each of the socket and probe are arranged, when mated in use, either side of an intersection between the through-bore and socket. The sealing arrangement is such that fluid within the fluid conduit exerts a net force resisting separation of said coupling members.

A technique facilitates formation of a connection between a first component and a second component. The first component and the second component may each comprise a tubular component. Additionally, the second component is secured to the first component via a coupler which is constructed to establish a hydraulic chamber between the coupler and at least one of the first component and the second component. Application of hydraulic pressure in the hydraulic chamber causes a desired preloading of the first component and the second component across the connection.

A metering device with a product conduit section, through which a base product forcibly flows, with at least one storage container for an additive, which is connected with an associated metering point respectively via a removal conduit, which is arranged on or respectively in the product conduit section, with a mechanism for forcibly conveying the additive, with quantity-based capturing of the base product and of the additive, with sterile steam and with a control device assigned to the metering device. The metering point is provided within a metering valve, which forms a product chamber, into which the product conduit section opens and from which it exits, an initial chamber and a partial chamber as well as a receiver of an end section and of a terminal side.

A tamper-resistant hydraulic connection may include a fitting that has a flange, a head, and a central body disposed between the flange and the head. The head may have lobes that protrude radially relative to the central body. The fitting may be inserted into a port where a fluid-tight connection is formed. A central opening of the port includes pockets where the lobes of the head are retained, with the pockets preventing rotation and longitudinal retreat of the lobes. An elastic member disposed on the fitting may be compressed longitudinally between the flange of the fitting and the port. The fitting and the port may be sized and shaped such that assembly of the tamper-resistant hydraulic connection requires pushing the head into the central opening longitudinally past a first radially-extending plane where the pockets are located, rotating the head, and moving the head longitudinally back into the first radially-extending plane.
