A fluid connector, including a connector body, including a first through-bore, a first surface, a second surface, and a flange, a retaining clip operatively arranged to engage the first surface, the retaining clip being radially expandable within the connector body, and a retaining plate arranged to be inserted into the first through-bore, including a distal surface arranged to engage the second surface, a proximal surface, and a second through-bore, wherein the flange is operatively arranged to be crimped radially inward around the retaining plate.

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 cartridge for a fluid connector including a connector body having a bore and a flange, and a tube end form, the cartridge including a first end, a second end, a through-bore, a first radially outward facing surface including at least one aperture extending radially inward to the through-bore, and a retaining clip including at least one protrusion operatively arranged to extend into the through-bore.

In a flare fitting structure in which a flared portion that is formed in an end of a flared tube and faces a connected member is pressed by a flared nut to connect the flared tube to the connected member, the flared tube is formed by flaring a cylindrical tube including an original tube and a coating layer that coats a surface of the original tube, the flared portion includes a flare inclined plane that faces the connected member, and the flare inclined plane is formed with a machining portion in which the original tube is exposed by a machining operation.

A fluid control assembly includes a body having a female threaded end port, and an end adapter including a male threaded end screw threadably assembled with the female threaded end port, an end connector, and an internal passage extending from the end connector to the end screw. One of the body and the end adapter includes at least one outer peripheral recess, and the other of the body and the end adapter includes a peripheral flange. A portion of the peripheral flange in circumferential alignment with the at least one recess is deformed into interlocking engagement with the at least one recess to rotationally secure the end adapter with respect to the body.

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.

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 clamp ring type metal seal gas pipe joint is connected to one end of a gas pipe, and includes a fitting joint, a nut, and a clamp ring. Axial contact surfaces of the clamp ring and the fitting joint are respectively provided with a convex portion configured in a convex V shape and a concave portion configured in a concave V shape matched with each other, so that an end part of the gas pipe is compressed and self-flared to form a sealing part when the fitting joint is tightened. In the process of tightening the nut and the fitting joint, the end part of the metal bellow is compressed and self-flared by the convex portion of the clamp ring and the concave portion of the fitting joint to form a cone surface to realize limit fixation and form a double sealing.

A connector for use with a dialyzer to connect a conduit from a dialyzer with a conduit from a dialysate source. The connector includes a sleeve (female component) and a collet (male component). The sleeve has a generally cylindrical shape with an opening at one end having a circular shape with at least one slot positioned along the periphery of the circular shape. The sleeve also includes at least one flexible finger having a barb at a free end. The collet is configured to be housed within an interior chamber of the sleeve and has first and second gaps to house the barbs and first and second deflectable flanges to lock into recesses in a conduit.
