A tubing clamp and method using an inner ring providing shape support to a layflat tubing to provide a compression surface against which an outer split ring with segmented pressure fingers can be compressed using an overcenter clamp to secure a back folded first end of a piece of tubing to a second overlaid tubing end.

A duct coupling system includes a first duct with a perimeter attached to a compliant sealing gasket and a second duct with a perimeter attached to an annular component sized to interface with a seat of the compliant sealing gasket. The compliant sealing gasket can be selectively tightened around the perimeter of the first duct by engaging a tightening mechanism of a clamp to selectively tension a cable with opposing first and second end portions attached to the clamp and a longitudinal central portion encircling a perimeter of the compliant sealing gasket. Tensioning of the cable causes circumferential compression of the compliant sealing gasket and forms a seal between the first duct and the second duct.

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.

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).

An enhanced seal may comprise an inner portion and an outer portion. The inner portion may comprise an inner cylindrical portion and an inner annular portion. The outer portion may comprise an outer cylindrical portion and an outer annular portion. The inner portion may be made of a harder material than the outer portion and may provide support to the outer portion.

The assembly (1, 10) for irrigation, comprises a first and a second hose (2, 3) and comprises at least one connector (4, 5, 50) equipped with an attachment unit (4) adapted for the removable connection with tools for irrigation or water dispensers. The connector (4, 5, 50) comprises a first connection element (43) coupled to an end of the first hose (2) and a second connection element (51, 52), distinct from the first element (43) and coupled to one end of a second hose (3).

A metal to composite tube joint including selecting an elongated interior fitting constructed with an exterior barrel, reduced in exterior diameter to form a distally facing annular shoulder and then projecting still further distally to form an interior sleeve having a radially outwardly facing bonding surface. A metal outer sleeve formed proximally with a collar constructed for receipt over the barrel and increased in interior diameter and projecting distally to form an exterior sleeve having a radially inwardly facing bonding surface cooperating with the first bonding surface to form an annulus receiving an extremity of a composite tube and a bond bonding the extremity of the tube to the bonding surfaces.
