A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped. The crimping tool has a simple structure and good crimping performance, so that the workpiece is uniformly stressed and burrs on the workpiece can be reduced.

A compact hose assembly device may include a housing defining a cavity and a hingedly attached door to enclose the cavity. Within the cavity, the compact hose assembly device may include at least one sliding drawer or similar storage device. The compact hose assembly device may include an air-over-hydraulic crimping machine on a sliding drawing or substrate, the air-over-hydraulic being in operable communication with an air compressor, hydraulic foot pedal pump, and the like for operation. The compact hose assembly device may be constructed and arranged for convenient, low downtime, on-site hose repair or assembly.

A connection socket for a tubular connection includes a socket cup having a metal alloy composition and a sealing portion. A primary seal is positioned within the sealing portion. The primary seal includes an elastomeric material having a service temperature. One or more spacer rings are positioned within the sealing portion. A secondary seal is positioned within the sealing portion. The secondary seal includes a metal composition, wherein the secondary seal has a melting temperature at or above the service temperature of the primary seal. One or more locking rings are positioned within the sealing portion, wherein each of the one or more locking rings comprises a biting feature defined along an internal circumference of the locking ring.

A tube coupling for coupling a first tube and a second tube. The tube coupling includes an inner shroud including a ball portion and an outer shroud including a socket portion. The socket portion receives the ball portion. The tube coupling includes a compressive ring configured to elastically compress the outer shroud onto the inner shroud. The ball portion and the socket portion form a ball and socket joint. The ball and socket joint allows relative angular movement and relative axial movement between the inner shroud and the outer shroud.

A crimping tool for crimping a metallic crimp ring. The crimping tool includes a first crimp die having a first curved contact surface and a second curved contact surface, the second curved contact surface spaced apart from the first curved contact surface, and a trench extending between the first curved contact surface and the second curved contact surface. The crimping tool also includes a second crimp die cooperatively engageable with the first crimp die having a first curved contact surface and a second curved contact surface, the second curved contact surface spaced apart from the first curved contact surface, and a trench extending between the first curved contact surface and the second curved contact surface. The trench of the first crimp die and the trench of the second crimp die forms an annular bead in a center portion of the metallic crimp ring.

A press fitting device (1) for establishing a fluid-tight connection with at least one pipe section (10), the press fitting device being configured to generate a sound when a gaseous fluid flows along or through the press fitting device a) in a pre-press fit condition, in which a connection with the at least one pipe section is established and before the connection is press-fit; and/or b) in a press fit condition, in which the connection is press-fit, if the connection is not fluid-tight.

A press fitting device, components and method provide one or more indicators to provide a visual indication that the fitting has been properly pressed around a tube and that the correct amount of pressure has been provided to create a permanent seal. In embodiments, a sealing ring is retained within an indentation of a main body component of the fitting and the sealing ring is expandable upon compression to be visible through an opening in the main body component.

A manipulator and placement tool for conduit-joining sleeve is an open-ended cylinder having a first half-cylinder and a second half-cylinder. The first and second half-cylinders are hingedly coupled to one another at first circumferential ends thereof. A retainer couples the first and second half-cylinders at second circumferential ends thereof. A first axial end of the open-ended cylinder is configured to slidingly receive an open-ended conduit-joining sleeve therein wherein the sleeve is fully encased by the open-ended cylinder. A second axial end of the open-ended cylinder has an annular ledge at an internal region of the open-ended cylinder. The annular ledge prevents the sleeve from passing axially through the second axial end.

A press-fitting component (1) including at least one main body (2) having at least one inlet (4), at least one outlet (5) and at least one channel (3) connecting the inlet (4) with the outlet (5), as well as at least one press-fitting (90) defined in correspondence of at least one of the outlet (5) and the inlet (4) of the main body (2). The press fitting further comprises a predetermined number of projections (9) emerging internally from the main body (2) and made in one piece with the main body (2). A process of assembling the component (1) with a pipe and a process of manufacturing the component (1).

A fluid transfer assembly is described that includes a fitting comprising a lumen having an opening, and at least one barb, the at least one barb extending circumferentially around the lumen proximate to the opening. The assembly also includes a flexible conduit, a deformable sleeve, and an elastomeric liner disposed between the sleeve and the conduit. The fitting extends at least partially into the conduit such that the conduit extends over the at least one barb. The elastomeric liner applies substantially 360 degree radial pressure to the conduit such that the conduit is sealingly compressed around the at least one barb of the fitting. The assembly is fluid tight up to a burst pressure of the conduit.
