A waterjet system in accordance with at least some embodiments of the present technology includes a tube configured to carry ultrahigh pressure liquid, and a fitting connected to an end portion of the tube. The fitting includes a body and a clamping block that secures the tube to the body. The body includes a recess, a passage extending inwardly from the recess, a sealing surface extending around the passage, and a sidewall extending around the sealing surface. The sealing surface meets the sidewall at an annular corner within the recess. The clamping block includes first, second, and third through holes spaced apart from one another. The tube extends through the first through hole and is secured to the clamping block via a threaded connection. First and second clamping bolts extend through the first and second through holes, respectively, and into respective threaded openings in the body.

The present invention is an imprint device for imprinting a unique identification mark on a surface of an object with imprinting particles of different sizes that increase uniqueness and without the need for electric power. The imprint device includes a vertical member, a hammer member, a trigger assembly, a charging unit, a barrel and at least one pocket. In the operative configuration, a trigger of trigger assembly is activated such that hammer member impacts a cartridge filled with at least one munition of imprinting particles and releases imprinting particles. The imprinting particles travel through the barrel where acceleration is increased and impact on surface is made to form microcraters and unique identification marks. The imprinting particles can be of same size, material and shape or they can be of different sizes, material and shapes or the combination thereof for increasing uniqueness.

Embodiments of the present disclosure may include a waterjet cutting machine, including a frame, a cap including a liquid inlet port and an abrasive supply port, a pivoting assembly disposed at the second end of the frame and further including a nozzle that may be pivotable about a horizontal axis between +/130 degrees relative to the horizontal axis. The nozzle may be configured to discharge a high-pressure liquid and an abrasive to perform a shape nozzle and taperless cutting operation. The waterjet cutting machine may also include a shaft assembly disposed within the frame that may rotate about a vertical axis as well as a rotary bowl with a liner selectively removably coupled to the shaft with standoff fasteners and a plurality of set screws. The rotary bowl and liner may protect the inside surface of the waterjet cutting machine from the effects of the abrasive for optimal performance.

An abrasive media blaster assembly includes a container to hold at least one abrasive media, an external air source to provide a compressed air supply, a reservoir to hold water and rust inhibitor solution and a venturi blaster gun. The venturi blaster gun comprises an exterior nozzle, a media blaster block and a trigger with a handle. The fittings in the media blaster block create a venturi effect and draw the water and rust inhibitor solution so as for it to mix with the abrasive media where the dustless blaster sprays the mix to remove surface finishes from a metal surface and simultaneously provides a rust inhibitor to the surface, thereby allowing the device to be capable of performing any one, two or all of dry media blasting, slurry blasting, and water blasting.
