A hand disassembly rotational valve coupling for tool less manipulation by a user's hands and fingers using a coupling housing body defining an output seal aperture close to an output handle retention slot and slot lip, where the slot lip has a slot handle gap and an output seal retainer including a coupling handle ring with a first triangulated offset body retention ears and hand graspable handles separated by a ring handle gap for hand assembly and disassembly from the coupling housing body.

A delivery assembly for a crop input delivery system. The delivery system includes a boom adapted to be supported at a proximal end from a mobile vehicle, the mobile vehicle holding a supply of the crop input, the boom supporting a conduit having a proximal end in fluid communication with the supply of crop input. The delivery system further includes a first coupler and a second coupler. The first coupler is supported on a distal end of the boom and is coupled to the conduit. The second coupler is in fluid communication with a storage tank disposed on the implement, the second coupler configured to fluidly couple with the first coupler. A clamping assembly releasably couples the first and second couplers in fluid engagement.

A connector is provided comprising a hollow connector body having a central aperture and a hollow tube that is rotatable within the central aperture without rotating the hollow connector body.

A fluid coupling for fuel lines in motor vehicles, includes a housing having a receptacle for a counterpart, a blocking member in the receptacle and engageable behind a blocking rib of the counterpart to fix the counterpart in the receptacle, and a detection sleeve axially movable in the receptacle, and having a first engagement portion, which engages with the blocking rib to move the detection sleeve axially into a detection position, and at least one second engagement portion arranged behind the first engagement portion and, when the counterpart is pulled out, engages with the blocking rib to move the detection sleeve out of the detection position, into the initial position, and the detection sleeve includes at least one detection portion (64), received within the receptacle in the initial position so the detection portion is not visible from the outside and, in the detection position, visibly protrudes from the receptacle.
