The heater tube for motor vehicle exhaust gas heating has a plastic tube (1) over which a heating wire (2) is helically wound covered by a helically wound adhesive band (3) having adhesive on the underside only, insulating the second heater wire winding fr...

The heating arrangement has an electrical heat source for heating a fluid in a motor vehicle fluid line (1) and a heat conducting device (8,9) connected to the heat source. The heat conducting device is connected to a clamp (3,4) for connecting the heat co...

Thermoplastic tubular support for connecting to a fluid line on a container (6) comprises a first part (1) and a second part (2) containing a reinforcing filler whose amount and type are selected so that the creep tendency and swellability of the second pa...

Material of the second component (2) is largely enclosed by material of the third component (3). Their volume ratios are selected such that their overall fuel permeability, strength and swelling closely resemble those of the second component. Materials of ...

The second component (2) is completely encapsulated by the first component (1), as far as an injection point (6). This point is as remote as possible from the surface (7) which is to be welded to the tank (5). The first component is injected over the still...

The device has a fluid conduit (2) made of plastic material is connected to a pressure compensation container (1) that is made of plastic material. A coupling unit (3) with a ribbed pipe unit is pressed at the free end of the fluid conduit. The fluid condu...

A plug-in coupling with two tubular coupling parts (1, 2) that can be plugged together to connect two fluid-carrying components has a first annular groove (13) in an insertion section (14) of one coupling part (2) and in a receiving section (6) of the othe...
