A connector includes a seat portion and a body portion. The seat portion includes a seat having a first curved surface. The body portion includes a curved body having a second curved surface. A nut portion is screwed to the seat portion, with a flexible portion and washer disposed therebetween. To connect the seat portion and the body portion, the curved body can be inserted through an opening of the nut portion, and the flexible portion and washer. The flexible portion may resist, but not stop, the curved body from being moved therethrough. The curved body may be seated within the seat and configured such that angular and/or rotational adaptation of the seat portion relative to the body portion is permitted. The nut portion can be adjusted to compress the flexible portion such that the curved body is retained in the vicinity of the seat, while still permitting angular and/or rotational adaptation of the seat portion relative to the body portion.

An adjustable nozzle assembly includes a receiver having a fluid inlet configured to be fluidly coupled to a fluid source and an internal surface defining a reception chamber fluidly coupled to the fluid inlet, a swivel member disposed in the reception chamber of the receiver, a nozzle coupled to the swivel member, fluidly coupled to the reception chamber, and configured to discharge fluid along a discharge axis, and a restriction member coupled to the receiver such that the swivel member is positioned between the receiver and the restriction member. The swivel member has an external surface including a substantially spherical external surface portion in contact with the internal surface of the receiver. The restriction member has a surface geometry defining a passageway through which the nozzle extends, and the surface geometry limits rotation of the swivel member within the receiver.

A double ball pipe coupling with two axes for connecting fluid pipes or conduits at eccentric angles while reducing or eliminating frictions loss. The coupling also provides movement of pipes or fluid pathways that are under low to high pressures. Two outer shell halves contain two ball joints with protruding connections and or outer fittings for most applications. The shell halves being mostly uniform or oblong or distorted for highly non-collinear connections. The ball joints containing pathways rotate within each shell half while permitting fluid flow as intended while greatly reducing restrictions.

An articulated conduit device may include at least two arms pivotally connected at proximal ends of the arms by a joint, a tiltable adapter at a distal end of each of the arms, capable of tilting up to a predetermined angle, and a locking mechanism operable by a single action to concurrently lock or unlock the arms and adapters in a user-defined orientation and direction. A continuous cavity is defined within the device between external openings in the adapters and through the arms and joint so as to allow fluid to flow between the external openings of the adapters.
