A joint for connecting the lengths together has a body having a longitudinal axis and a throughbore and at least one flexible coupling to permit at least one of the ends of the respective first and second lengths of load bearing flexible conduit to move relative to the longitudinal axis of the joint.

An inner ring 4 of a pipe joint 1 includes a bulge portion 6 formed at an axially outer end portion thereof so as to project toward a radially outer side, and to be press-fitted into an end portion of a tube 8, and has a fluid flow passage 4a formed on a radially inner side of the bulge portion 6. The bulge portion 6 is formed so as to be tapered from an axially inner side toward an axially outer end thereof in an axial cross-sectional view, and has a flat surface 6e formed at the axially outer end thereof and extending in a radial direction.

Provided is a connection assembly for connecting to inner and outer hoses. The connection assembly includes a first connector assembly, a second connector assembly, a first hose connector assembly coupled to the connector assembly and configured to be coupled to the inner and outer hoses, the first hose connector assembly including a first tube connector configured to be coupled to the inner hose and a first collar configured to be coupled to the outer hose, and a second hose connector assembly coupled to the second connector assembly and configured to be coupled to the inner and outer hoses, the second hose connector assembly including a second tube connector configured to be coupled to the inner hose and a second collar configured to be coupled to the outer hose, wherein the second tube connector has a cross-sectional area that is smaller than a cross-sectional area of the first tube connector.

A connecting device for connecting two or more components to one another, includes an inlet section and an outlet section. The inlet section and the outlet section respectively include one or more connectors for each of the two or more components, with one or more passages extending between the inlet section and the outlet section, with the connecting device being of single piece design and being plastic.

A hose connecting device has a connector, an inner locking ring, an outer connector and a tubal body. The connector has an insertion section and an engaging section, the engaging section has a size greater than the insertion section, and the engaging section further has a stopping ring at a top end. The inner locking ring is jacketed onto the engaging section of the connector and abutting the stopping ring of the connector. The inner locking ring has an outer threaded section and an abutting portion disposed at a bottom end of the inner locking ring. The outer connector has one of a female connector and a male connector, and a channel, the channel has a positioning step at a middle portion, an inner threaded section disposed below the positioning step of the channel. The tubal body is jacketed onto the insertion section of the connector.

A pitot tube includes an outer tube extending from a first tube end to second tube end. The second tube end defines a tip portion of the pitot tube. A tube sleeve is located inside of the outer tube and defines a tube passage extending from the first tube end to the second tube end. A heating element is located between the outer tube and the tube sleeve. The heating element is isolated from airflow into the tube passage. A method of forming a pitot tube includes installing a heating element to an outer surface of a tube sleeve, the tube sleeve defining a tube passage of the pitot tube. The tube sleeve is secured in an outer tube such that the heating element is between the tube sleeve and the outer tube and is isolated from airflow through the tube passage.

Disclosed is a fluid connection system including a sleeve, a pipe and a fluid connector, the fluid connector including at least one rigid body made from a sterilizable biocompatible material, and the pipe including a flexible connection portion made from a sterilizable biocompatible material that is at least partially elastomeric. The fluid connector and the flexible connection portion of the pipe are assembled to one another, with the flexible connection portion of the pipe surrounding the rigid body, and the sleeve being shrunk tightly, but with free movement, on the pipe.

A fluidic connection assembly and methods for quickly connecting or disconnecting a tube to a port by hand and without the use of tools. A body is adapted to receive a tube therethrough, and may have at least two sides which are hinged. Each of the hinged sides has corresponding latching portions or projections located near a lower end of the body. These projections are adapted to fit into a port or other fitting and be securely held in place. The assembly may include a tube extending through a body and through a spring located between the end of the body and the end of the tube, whereby the spring exerts a force directly or indirectly against the end of the tube and against the body, thus holding the tubing securely and sealingly engaged in the port when the assembly is connected. The body may further comprise an additional body or an adapter, and/or a cap and latch. A second spring may be used to push a projecting member into a groove or notch of an adapter when an end of the adapter is inserted into one end of the latch or the body. The fluidic connection assembly is useful in analytical instrument systems, such as for in vitro applications and/or in high pressure applications, among other things, and may be used in methods for connecting, or disconnecting, tubing or a fluidic connection assembly from a port or other fitting or connection.

A structure of a resin-made pipe joint includes a sleeve which is press-insertable from one axial side into one longitudinal end portion of a flexible tube to flare the one longitudinal end portion to hold the flared state, a joint body which is couplable to the sleeve, and a union nut which is fastenable to the joint body to hold a state where the sleeve press-inserted into the one longitudinal end portion is coupled to the joint body. The sleeve has a taper-like first outer circumferential surface, a second outer circumferential surface having an outer diameter that is smaller than a maximum outer diameter of the first outer circumferential surface, and an annular step portion which is an annular step portion that is disposed between the first outer circumferential surface and the second outer circumferential surface and comprises an edge portion on a side of the first outer circumferential surface.
