Apparatus and associated methods relate to a shapeable conduit. In an illustrative example, the shapeable conduit may have a circumferentially flexible wall extending along a longitudinal axis. The wall may, for example, define a lumen configured to receive one or more cables. Multiple longitudinally extendable manually deformable axial stiffening members may, for example, be circumferentially distributed in the wall. A releasable coupling mechanism may, for example, have at least two mating engagement members. The engagement members may, for example, releasably engage in an enclosed state such that the wall circumscribes the lumen. The engagement members may, for example, be tangentially separable into an open state such that the cables can be radially transferred between an interior and an exterior of the lumen. Various embodiments may advantageously be manipulated such that the axial stiffening members cause the flexible wall to retain cables enclosed within the lumen in a desired configuration.

A hose joint assembly includes a fitting, a hose receivable onto the fitting, and an adhesive for bonding the hose and the fitting together. For example, the adhesive is a microencapsulated two-part epoxy adhesive that functions as a lubricant when assembling the hose onto the fitting before curing.

A pipe coupling construction which can be used for coupling of a high-pressure pipe includes an inner bush of a non-metallic material and an outer bush, which bushes in axial section have parts which mesh with each other in order to transmit axial forces. The inner bush can be fused or adhered to an outer cover layer of the pipe. The coupling has a metal sleeve construction. The outer bush has an outer bush protruding end which protrudes with respect to the inner bush and the metal sleeve construction is at least partially located within the outer bush protruding end. The metal sleeve construction and outer bush in axial section have parts which mesh with each other.

A connector includes a body having a throughway with an open end. A shoulder in the throughway faces the open end and supports an O-ring. A collet in the open end of the throughway has a plurality of legs extending into the body away from the open end, each engaging with the body and having an inwardly facing tooth to grip, in use, a tube in the throughway. The body has a plurality of fingers extending to the open end. A cap fits over the open end of the body and extends from the open end towards the opposite end. The cap has a plurality of recesses in a wall at the open end into each of which one of the fingers is retained by a snap fit. The radially inwardly facing faces of the fingers of the body incline inwardly towards the open end providing a cap angle for the collet.

Illustrative Embodiments may provide for an apparatus and method for fitting a first tube to a second tube. The apparatus may have a first section and a second section. The first section and the second section may engage each other to form a spreine. Each section may engage a sleeve. The spreine may encircle the sleeve encircling the first tube. The spreine may include a slider that may receive a force that may move the spreine and the sleeve, engaged within the spreine, and fit the first tube to the second tube. Fitting the first tube to the second tube may include engaging the sleeve with a first O-ring that may encircle a first ferrule in the first tube, and the sleeve simultaneously engaging a second O-ring encircling a second ferrule in a second tube.

A duct system with multiple flex duct sections includes a duct take off, a duct register boot, at least one flexible duct assembly that includes an inlet coupler, an outlet coupler, and a duct section. The inlet coupler and outlet coupler are terminally connected to the duct section completing the flexible duct assembly as the number of duct assemblies determines the length of the duct system. The duct takeoff is mounted to the inlet coupler, and the duct register boot is mounted to the outlet coupler as the duct takeoff is in fluid communication with the duct register boot through the flexible duct assembly. Additionally, an air controlling device can be mounted with respect to three different places, wherein the three different places are in between two couplers, the coupler and the duct takeoff, and the duct register boot and the coupler to improve the efficiency of the duct system.

The invention relates to the production of profiled hose nipples. The invention was based on the object of providing a method and an apparatus which allow hose nipples of the type outlined in the introduction to be produced in a simple manner such that the formation of burrs is avoided and there is no reduction in diameter. This object is achieved in that during the forming of pipe portions (1) in the apparatus (2, 7, 9) according to the invention in the region of the subsequent ring-shaped webs (4) of the nipple profile (3), the material of the pipe portion (1), at its outwardly pointing end (4), does not come into contact with the tool in the region of the parting joints (6) of the apparatus (2, 7). This can be realized by additional cavities (14) in the tool (2, 7).

A swiveling hose coupler assembly for inhibiting hoses from becoming kinked includes a first male fitting that is insertable into a female end of a first hose. The first male fitting is hollow to pass a fluid from the first hose outwardly through the male fitting. A second male fitting is rotatably coupled to the first male fitting such that each of the first male fitting and the second male fitting extends along a common axis, and the second male fitting is rotatable about the common axis. The second male fitting is insertable into a female end of a second hose to inhibit the first hose and the second hose from becoming kinked. The second male fitting is hollow to pass the fluid from the first male fitting into the second hose.
