A coaxial outlet (10) comprises an outer outlet port (11) in communication with the first inlet port (3) and an inner outlet port (12) in communication with the second inlet port. The stem (2) comprises a tubular body with a main axis (31) with an inlet and a connector for attachment to the keg at one end. The second end of the stem opposite to the first end has an outlet in fluid communication with the inner outlet port (12) and comprises a ball joint (61) rotatably mounted in and sealed with respect to the main body (1) so as to be rotatable (12) about the main axis (31) of the tubular body and rotatable (67, 68) to a limited extent about axes perpendicular to the main axis.

Abstract: A tube coupling comprising having a coupling body with an opened ended throughway to receive a tube. A collet is located in the open end of the through way having a ring and flexible arms extending generally axially of the ring into the throughway. The throughway has a tapered surface convergent towards the open end and the collet arms have heads at their distal ends for engaging the tapered surface and a tube extending through the collet into the throughway to be compressed against the tube by the tapered surface with outward movement of the collet with respect of the throughway to secure the tube in the throughway. A collet lock is formed on the collet, and the collet has a locked rotary position Either the body or the collet has a cam surface and the other has a cam follower.

Abstract: An end stop for a fibre optic cable tube which is open at one end and closed at the opposite end. A connector at one end connects to a respective tube. An annular wall extends from the closed end and is spaced radially inwardly from the outer wall of the housing defining an air gap. An inner face of the annular wall receives the tube. The annular wall and housing may be transparent. The connector may be a collet within the housing which engages on a cam feature in the housing.

Abstract: A reducing fibre optic cable tube connector with a plastic body having a connector at either end for connection to a respective tube. The body has a wide portion terminating at a wide end and a narrow portion terminating at a narrow end to receive tubes of a different diameters. The two portions meet at a central region of the body. Each portion includes an annular inner sleeve extending from the central region and spaced from an inner wall of the outer body to define an air gap. At the central region the annular sleeves extend toward one another so the first and second air gaps are axially spaced by less than 1 mm.

Abstract: A connector for a fluid line includes a sleeve having a hollow portion at least partway therethrough. The sleeve includes an engaging portion. A collet having an engaging part is secured to the engaging portion. A grab part has one or more teeth configured to retain the fluid line, and the teeth are located in the hollow portion. A locking part is provided having a locking portion, and the locking part is configured to move from a first position to a second position where the locking portion locks with a locking piece to assist with forming a fluid seal with the fluid line.

Abstract: A mold for molding a body or cap for a connector. The mold comprises a mold body (1) and an axial core (2) which together define a mold cavity in the shape of the body or cap. The core has a sleeve (3) and an inner pin (4) each having complementary castellations (8, 10) which interdigitate in a first configuration. In the first configuration, the castellations (8, 10) are arranged such that respective recesses (11) are formed each bound by the proximal end of a first castellation (8) and the side walls of adjacent second castellations (10). Each recess has a shape to form a respective first portion of the body or cap. The sleeve (3) and inner pin (4) are axially movable to a second configuration in which the castellations (8, 10) are disengaged from one another. The inner pin (4) is rotatable to a third configuration in which the first castellations (8) can be axially withdrawn following a path occupied by the second castellations (10) in the first configuration.

Abstract: A pipe connector having a body with a tubular part to seal with a pipe. The tubular part has an outer face with a projecting feature to seal with the pipe. A collet is fixed to the body and spaced from the tubular part to form a cavity for the pipe. A locking cap is captive on and screwed onto collet to deflect the collet onto the pipe and the pipe onto the tubular part to seal between the body and the pipe. The collet has through slots at its distal end allowing the pipe to be visible when the connector is locked and unlocked. The inner diameter at an open end of the collet is optionally greater than the inner diameter of the distal part that receives the pipe. A method of forming the connector is also disclosed.

Abstract: A tube coupling comprising a coupling body (1) having an opened ended throughway to receive a tube (T). A collet (41) is located in the open end of the through way having a ring (52) and a plurality of flexible arms (53) extending generally axially of the ring into the throughway. The throughway has a tapered surface (43) convergent towards the open end and the collet arms have heads at their distal ends for engaging both of the tapered surface and a tube extending through the collet into the throughway to be compressed against the tube by the tapered surface with outward movement of the collet with respect of the throughway to secure the tube in the throughway. A collet lock is formed on the collet (41), the collet having a locked rotary position in which the lock holds the collet in an outward tube securing position and an unlocked rotary position in which the collet can move axially with respect to the throughway for release and engagement of a tube by the collet.

Abstract: A ball valve assembly includes a duct with a central passage for the flow of fluids. A ball valve is rotatably mounted within the duct. The ball valve has a through bore selectively alignable in an operational position with the central passage to allow flow through the valve assembly. A lateral opening is provided in the duct. A handle attached to the ball valve extends through the lateral opening such that it is accessible from outside the duct to allow rotation of the ball valve. The ball valve, handle and duct are sized so that the ball valve and handle together are insertable into one end of the duct in a first orientation to an intermediate position, from which position and orientation the ball valve and handle together can be manipulated without the ball valve leaving the duct to a final position with a second orientation in which the handle extends out through the lateral opening and the ball valve is in its operational position.
