Provided are a mechanical tube fitting for preventing bending fracture of a tube member to be joined when subjected to bending deformation, and a simple tube fitting structure including that tube fitting. In the tube fitting, a clearance between a tube member (32) to be joined and an outer pipe (12) or an inner pipe (14) which is coaxially inserted in the outer pipe (12) and gives a space between its outer surface and the inner surface of the outer pipe (12), in which space the tube member (32) is inserted, is sealed with a sealing member disposed between the outer pipe (12) and the inner pipe (14), and the above-mentioned components are fixed by caulking. The outer pipe (12) is configured to extend outwardly in its axial direction than the ends of the inner pipe (14).

A kit and a related method for connecting pipes, comprising: including: a tubular fitting having at least one access end for an end portion of a respective pipe to be connected; said access end of the fitting having at least one fluid-sealing gasket interposed between an inner surface of the fitting and an outer surface of the pipe; and a pressing tool configured to implement a radial plastic deformation action on the access end defining a stable coupling condition between said fitting and the respective pipe; the pressing tool comprising including at least one tooth extending radially with respect to the circumferential extension of the fitting and the pipe; said access end of the fitting comprising including at least one radial projection formed as a result of the plastic deformation action, said projection being at least partially inserted in the outer surface of said pipe.

A conduit outlet assembly for a rigid metal conduit raceway of an electrical system is provided. A conduit outlet assembly includes a gasket, a gripping ring, and a condulet assembly. The gasket is sized to circumscribe an outer surface of a rigid metal conduit of the rigid metal conduit raceway. The gripping ring is sized to circumscribe the outer surface of the rigid metal conduit. The condulet assembly is sized to receive the rigid metal conduit, and includes an adapter and a condulet. The adapter includes a compression section and a coupling section, wherein the compression section is sized to receive the rigid metal conduit with the gasket and the gripping ring disposed thereon. The condulet is sized to receive the coupling section of the adapter.

A pipe manipulation apparatus having a base frame and a sliding end slidable towards and away from the base frame, each of the base frame and sliding end having at least one pipe support coupled with a press clamp pivotable between an open position and a closed position, wherein in the open position, a pipe is placeable on to the at least one pipe support and, in the closed position, the inner surfaces of the press clamp and the pipe support define a bore in which a lengthwise portion of the pipe is receivable. The pipe manipulation apparatus may be portable, tiltable, and/or rotatable to accommodate pipes of various locations and angles.

The invention relates to tubing assemblies and methods for forming a fluidic connection to make the same. The assemblies include an outer tube having disposed therein a first inner tube affixed to the outer tube, a second inner tube and a support tube disposed in the second inner tube. The second inner tube is abutted against the first inner tube. A radial crimp is made in the outer tube over the second inner tube a distance x from where the tubes abut; the distance x being such that the end of the second inner tube seals against the end of the first inner tube. Various embodiments provide assemblies suitable for use with high fluidic pressure (e.g., greater than an about 70 MPa, approximately about 10,000 psi) and formation of chromatographic column assemblies comprising a capillary tube predisposed within the first or second inner tube prior to formation of the seal.
