A valve interconnector, suitable for use in combination with a receiver interconnector to couple a first hollow body to a second hollow body, is disclosed. The valve interconnector comprises a neck (7) to be secured to the first hollow body and further comprises a base cap (8) comprising an exterior tube portion (85) covering at least a portion of the external surface (7s) of the neck (7). The exterior tube portion and the neck are secured to each other with ability of relative rotation about a central axis. The valve interconnector is provided with a selector (44, 48) operative between the neck (7) and the exterior tube portion of the base cap (8) and configured for assuming at least a first position and a second position, in the first position the base cap being prevented from being axially released from the neck, in the second position the base cap being enabled to be axially released from the neck.

A fluid line connection for a pneumatic distribution system for an agricultural air seeder includes a female connector having an inside diameter with a groove and a male connector configured for internal assembly with the female connector. The male connector has an external tab that engages the groove to retain the male connector to the female connector when the female connector is rotatingly assembled with the male connector. The female connector is removed by rotating and disassembling from the male connector to access a conveyance tube or manifold for servicing these parts. A sealing member is assembled between the male and female connectors to form a fluid seal. A primary tube can be assembled between two fluid line connections to form a quick connect assembly. A fitting connector and a locking ring are assembled with a fluid line connection to retain a primary tube thereon for an air drill.

A method for producing a tube arrangement for the transport of tempering medium, in which base body sections are provided, which have congruently configured separating surfaces, wherein at least one functional element on at least one base body section is arranged in such a way that it can be in contact with the tempering medium, whereafter the base body sections are joined along the separating surface and bonded to one another to form the tube arrangement.

A gas stem assembly is disclosed including a vent tube having at least one protrusion extending radially from the vent tube and a receiver having a non-circular opening and an attachment surface at an end of the non-circular opening. The vent tube is at least partially insertable through the non-circular opening of the receiver when the vent tube and the at least one protrusion are aligned with the non-circular opening. The attachment surface of the receiver contacts the at least one protrusion to inhibit the at least one protrusion from passing back through the non-circular opening when the at least one protrusion is misaligned with the non-circular opening.

Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device while a locking ring of the first aseptic device is in an indexed initial position, rotating the locking ring to a secured position in which a compressive force is created and in which a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device can removed thereby resulting in a first a first sealing member of the first aseptic coupling device sealing with a second sealing member of the second aseptic coupling device to form a sterile fluid passageway.
