A connector for a structurally integrated line system of a vehicle, having a first end portion, a second end portion and a connecting piece extending between the first end portion and the second end portion, wherein the first end portion has at least one contact face for arrangement on a structurally integrated line, wherein at least one of the at least one contact face has a cutout which is surrounded by a closed border, wherein the second end portion has a flange connection for connection to a pipe.

A single piece structural connector is provided that includes a single machined aluminum piece having first and second circular ends including a plurality of bolt holes and a center hole. The connector also includes an alignment dowel positioned on the center hole. The alignment dowel is configured to tightly fit into a center hole of a pipe plate.

A conduit coupling adapter for securing attaching a conduit to an enclosure is disclosed. The conduit coupling adapter generally includes a first end for receiving a conduit and attaching to it via an adhesive, and a second end coupled to the second end comprises threads and is configured for attaching to an enclosure using a locknut.

A pipe fitting for expansion tanks includes a first part suited to be fixed to an expansion tank during production of the expansion tank, and a second part suited to be fixed to the first part, if necessary, even at a later moment than the production of the expansion tank.

An apparatus for sealing a hole or a shape in a surface, which, in an exemplary embodiment, may take the form of a sheet of a soft material containing an interior hole, an exterior surface, a top lip, and an outer area. It may likewise be contemplated for the sealing apparatus to feature a bottom lip. Part of the apparatus may be roughened or have a rough surface attached thereto, which may be imprinted into the interior portion of the body and the exterior portion of the body and the top lip, or both. An adhesive pipe sealant may be used along the rough surface and bonded to the increased surface area of the roughened region.

A conduit coupling assembly facilitates connection of tubing with a conduit section through which associated electrical wiring and/or cables are routed. The assembly includes a conduit coupling, which is joined the conduit section which projects above an associated concrete slab or the like. The conduit coupling assembly thus particularly facilitates routing of wiring from a conduit section positioned within a concrete slab or like flooring element, through the conduit coupling, and associated conduit or tubing.

A conduit coupling adapter for securing attaching a conduit to an enclosure is disclosed. The conduit coupling adapter generally includes a first end for receiving a conduit and attaching to it via an adhesive, and a second end coupled to the second end comprises threads and is configured for attaching to an enclosure using a locknut.

A heat exchanger includes tubes, a pair of tanks, and a connector. The tubes are stacked with each other in a stacking direction. The pair of tanks are disposed at both ends of the tubes and a longitudinal direction of the tanks extends along the stacking direction. At least one of the tanks is a connecting tank. The connector is disposed in a side portion of the connecting tank to fluidly connect a pipe to the connecting tank. The connecting tank has a tubular shape and includes a flat surface on the side portion. The connector includes a facing surface facing the flat surface. The facing surface is joined to the flat surface such that at least a portion of the facing surface extends beyond the flat surface in a lateral direction of the connecting tank.

The invention relates to a method for producing a polymer-enhanced pipeline element, in particular of a fire extinguishing installation, and to a pipeline element and a pipeline system of a fire extinguishing installation. It is proposed according to the invention to provide a first a first and a second hollow body, to align in each case one encircling edge surface of the hollow bodies with one another, to weld the two hollow bodies to one another along the encircling edge surfaces such that an encircling weld seam is generated which has a root extending on the inside of the pipeline element, and to apply a polymer-based layer to the inside of the pipeline element, wherein the polymer-based layer completely covers the inside of the pipe element and the root of the weld seam.

A kit for joining cylindrical tubes to form strong orthogonally joints for use in a variety of structures comprises a tool for modifying the cylindrical tubes to demonstrate cutouts of specified width and depth, a Steinmetz solid connector having a shape defined by the volume of intersection of the two cylindrical volumes of equal diameter joined orthogonally; and an adhesive means for securing said connector within said cylindrical tubes. Kits that comprise one-, two-, and four-piece Steinmetz solid connectors are described, as are alternative means and members to secure and shape the resulting joint.
