A double-tube radiator composed of at least one double tube, preferably of aluminum, the tube being composed of two tubes arranged concentrically, one inside the other, with distributor stubs disposed at their end areas. Each of the stubs have a neck with a supply channel running perpendicular to the longitudinal axes of the tubes, through which neck the oil or the like to be cooled is fed to or removed from the double tube. Provision is made for the distributor stubs to be designed as a sealing plug with cylindrical connecting areas mountable coaxially to the ends of the inner and outer tubes forming the double tube, said plug being provided with a chamber communicating with the supply channel, said chamber being located between the connecting areas for the tubes. The distributor stubs in the form of sealing plugs are drawn over the end areas of the double tube and held there securely, without welding of the inner and outer tubes forming the double tube, or soldering or welding of the distributor stub itself to the outer tube for securing it axially, so that aluminum tubing can be used for the double tube, for example, permitting a high degree of heat-exchanger efficiency to be achieved.

Disclosed is an elastomeric packing suitable for use in connections between a first part and second part wherein the packing is placed under a compressive force. The packing comprises a generally solid cross section having a recess therein for absorbing deformation of the packing due to the compressive force. Also disclosed is a fluid-tight sealed connection, e.g., in a heat exchanger, employing the disclosed packing.
