An adapter for connecting a cold-spray nozzle to a cold-spray machine includes a receiver having a first end and a second end and defining an internal space for receiving the cold-spray nozzle; an end cap engageable with the first end of the receiver for securing the cold-spray nozzle in the receiver and having an opening aligned with an outlet of the cold-spray nozzle; and a threaded connection at the second end of the receiver, the threaded connection being configured for connection to the cold-spray machine.

[Problem] To provide a pipe joint allowing reliable connection to a pipe P without flaring.

[Means of solving problem] The pipe joint includes a flare joint body 1F, a cap nut 2, and a stop ring 3. A curved pressure-contacting slope surface 32 of the stop ring 3 contacts a slope surface 5 with reduced-diameter tip of the flare joint body 1F under pressure to establish sealing by means of mutual contact between metallic surfaces. The pipe P is grasped in a tightly pressure-contacting state using a back tooth and a front tooth formed at a tip head 37 of a substantially cylindrical thin part 35 of the stop ring 3.

A valve including a main body which includes a fluid passage, a first port connected to the fluid passage, a second port connected to the fluid passage, and a first groove formed on an outer circumference of the main body at the first port. The first groove including a lower wall, and an upper wall including an inclined surface which extends away from the lower wall as the upper wall extends radially outward, the inclined surface being located on a radially outer portion of the upper wall. The valve further including a connection member attached to the first port, the connection member including a second groove on a radially inner surface of the connection member, and a retaining member disposed in the first groove and the second groove.

A fitting apparatus for fluidly coupling a plurality of pipes together includes a flexible bladder which fluidly couples a plurality of pipes together. A rigid shell is positionable around the bladder in an attachment position. The rigid shell comprises two portions which are couplable to each other to position the shell in the attachment position. Collars are provided which threadably attach to the rigid shell.

A kit for connecting to a processing container a device for feeding a liquid or semi-liquid food product, including at least: an internally hollow pipe having a first end and a second end, wherein at least one between the first and the second end includes an enlarged, external terminal portion; a receiving element provided with a hole for receiving at least the enlarged, external terminal portion at one end of the pipe and with an abutment for stopping the end of the pipe inside the hole; means for pushing and locking the enlarged, external terminal portion at the end inside the receiving hole in order to allow locking the enlarged, external terminal portion against the abutment.

A diesel exhaust fluid transfer circuit providing a fluid transfer connector for securely connecting a port fitting of a diesel exhaust fluid device to a diesel exhaust fluid hose. The fluid transfer connector comprises an attachment nut attachable to a port fitting of the diesel exhaust fluid device. The fluid transfer connector further comprises a hose adapter including a fluid conduit and an annular wiper seal coaxially aligned with the fluid conduit. With the attachment nut attached to the port fitting, the fluid conduit is slidable over the port fitting and connectable to the attachment nut, and the annular wiper seal wipes any residue on the port fitting as the fluid conduit is slid over the port fitting.

To provide a pipe in which the pipe having been fixed is prevented from being loosened by co-rotation. A pipe includes at least a first pipe and a second pipe and connects blocks each having an internal flow path and an open end of the flow path on a surface thereof. The other end portion of the first pipe is provided with an outward flange, and an annular gasket is interposed between butt end faces of the first and second pipes, and a male thread member that is inserted onto the first pipe, has male threads on a peripheral surface thereof, and abuts against the outward flange. The other end portion of the second pipe is provided with a cap nut member that is inserted onto the second pipe, has an outward flange, has female threads, and has an inward flange to be engaged with the outward flange.

A flow control structure of a water hose joint has: a hose connector, a coupler, a control section, and a hose. The coupler is coupled with the hose connector, the control section is sleeved on the coupler, and the coupler is inserted into the hose, so as to complete a flow control structure of the hose connector. By combining the hose connector with a connecting pipe and rotating the control section to adjust the relative position of the control section and the coupler to change the water flow, which has the effect of simple flow adjustment.

A fitting to interconnect water pipes or to connect pipes with valves or mountings. The connector housing has an O-ring seat, constituting two walls of a groove for an O-ring. The fitting comprises a clamping sleeve, having a first end provided with a flange, which forms a third wall of the O-ring seat groove. The flange is retained against the coupling housing by a nut screwed by hand onto outer threads on the coupling housing. The clamping sleeve is adapted to be clamped against a pipe which is inserted into the clamping sleeve, and the O-ring seals against the outer surface of the pipe.

An apparatus for hydrostatic testing of openings in items surrounded by a flange, such as flanged pipe sections, flanged pipelines, flanged hose assemblies, as well as other flanged equipment requiring periodic pressure testing.
