A ball swivel of the configuration typically utilized for pool cleaners includes male and female portions featuring an interposed stopper to reduce friction and prevent the male and female portions from binding under load, while improving sealing and continuing to allow rotational and pivotal motion.

The invention relates to a hydraulic coupler. The coupler comprises a male and female coupling, each with a poppet valve moveably supported by an inner surface of a main body of the coupling. Each coupling further comprises a movable connector part in its front end with a spherical rear surface accommodating a spherical connector seat in the main body, where the connector is provided with sealing means between the connector part and the main body of the coupling.

Adapter, tyre parameter monitoring system and method for mounting a tyre parameter monitoring system onto a wheel rim In an embodiment, a tyre parameter monitoring system (2) is provided that comprises an electronic module (4) with a fitting (6) for a snap-in valve, a ball stud (8) coupled to the fitting (6) and a valve stem (10) for a clamp-in valve. The valve stem (10) has a ball socket (12) that is coupled to the ball stud (8) for form a ball joint such that the valve stem (10) is positionable at different angles to the electronic module (4).

A slip-on adapter that is adapted to be coupled to existing adapters that have already been developed. The slip-on adapter couples to existing adapters by positive retention on either the outside diameter or inside diameter of the existing adapter. For example, the slip-on adapter can include an O-ring that grips the outside diameter of the existing adapter that it is slipped onto. The slip-on adapter can also be used as a “flip adapter” with different geometries at both ends for use with two different size ball joints. This allows for less expensive adapters for new size ball joints by connecting to existing adapters, rather than requiring full machining of a new adapter.

A pipeline pressure isolation system that can have a multi pressure head plug module, a hydrotest module and/or a multiwedge pipe interface.

A coupling assembly, to be flowed through by fluid, for coupling two components has a coupling element and a ball joint assembly with a female ball joint element, a male ball joint element, and a securing element. The female and male ball joint elements form a ball joint by form fit. The male ball joint element has a ball segment and the female ball joint element has an expandable ball segment. The ball segment of the male ball joint element engages the expandable ball segment so that the female ball joint element at least partially encloses the male ball joint element. The securing element contacts externally an outer contour of the female ball joint element. The coupling element forms one of the female and male ball joint elements. One of the two components forms the other one of the female and male ball joint elements.
