A joint structure of high pressure grease gun tubing is an oil pipe connected to a high pressure grease gun, and the end of the oil pipe is connected with a rotatable joint, and the joint includes a joint connected with the oil pipe for that the grease can pass through the middle through hole, and the end of the joint is sequentially provided with a first shaft part, a second shaft part with an outer diameter slightly larger than the first shaft part and a caulking groove for the oil sealing washer and the oil sealing ring to be sleeved, and a rotary joint has the thread on the outside end and the grease can pass in its middle. The inside end of the rotary joint is embedded into the caulking groove of the joint, and a first coupling part for coupling of the first shaft part is arranged in the middle of the rotary joint, which is closely fitted with the oil sealing ring and the oil sealing washer. A second coupling part for coupling of the second shaft part makes that the rotary joint can be rotated on the joint without falling out, and that it is easier to connect with the grease nozzle of the lubricating grease, and also there is no leakage under the action of high pressure grease.

A process analyzer adapter includes: a first part connectable to a process analyzer, the first part being rotatable about a first axis; a second part; and a third part. The first part is rotationally connected to the second part. The second part is rotationally connected to the third part. The second part is rotatable about a second axis, rotation of the second part about the second axis tilting the first axis. The third part is connectable to a flange of an industrial process equipment.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.

A hose connector has a first connecting joint, a second connecting joint, and a connecting duct. The first connecting joint comprises an inner neck rim having an inner threaded aperture and a containment space connecting to the inner threaded aperture. The first connecting joint further comprises a threaded outer wall, and a bottom surface of the neck rim has a plurality of engaging grooves. The second connecting joint comprises a hollow base having a neck section connected to a lip, and the neck section is configured for insertion in the containment space of the first connecting joint. A top surface of the lip has a plurality of engaging protrusions pushing against the neck rim or engaging with the engaging groove. The connecting duct comprises an outer threaded section and an enlarged flange, and the connecting duct is mounted through the neck section and the lip.

A swivel fitting adaptor having an elastomeric insert, and a swivel fitting assembly using the adaptor and insert, are disclosed herein. The swivel fitting assembly includes retention and sealing features that allow a barbed fitting, such as a tube, hose or vent fitting, to be installed by hand either before or after the adaptor and insert are installed in a threaded port. It is suitable for use in a variety of low to medium pressure fluid passage and venting applications.

A connector assembly for connection to a preconditioned air port on an aircraft that includes a rotatable coupling, a retractable latch, and a protective cage. The retractable latch is actuated by rotation of the protective cage relative to the upper coupling section of the coupling. The protective cage surrounds the coupling and includes at least a first and second protective bumper at opposite ends of the protective cage. The protective cage protects the connection from coming in contact with the ground.

A rotary feedthrough for the feedthrough of a powder-gas mixture from a stationary machine part into a rotating machine part, with a seal in the form of two flat circular-ring-shaped sliding seal surfaces arranged one on the other in a sliding manner, which sliding seal surfaces are arranged concentric to the axis of rotation of the rotating machine part and which can be moved apart from each other in the axial direction, so that they form a gap, wherein the seal is embedded in a purge chamber having at least one gas inlet and at least one gas outlet.

An elastomeric press-in-place swivel fitting adaptor and a swivel fitting assembly using the adaptor are disclosed herein. The swivel fitting assembly includes retention and sealing features that allow it to be installed in a threaded port by hand. It is suitable for use in a variety of low pressure fluid passage and venting applications.

The disclosure describes a rotary union that includes rotating and non-rotating machine components, each having a sealing ring, which can together form a mechanical face seal. A rotor disposed on the rotating machine component includes one or more magnets. A sensor array disposed in the housing includes a plurality of sensing elements that are integrated with a control device, a communication device, and a power storage device. The sensor array further includes a magnetic pickup coil disposed to closely overlap the outer periphery of the rotor. When the rotating machine component rotates, the magnet creates a rotating magnetic field that cooperates with the magnetic pickup coil to produce electrical power to operate the sensor array.
