Abstract
A plug ( ) for sealing a filler neck ( ) of a fuel tank has a cap ( ) which is dismountably attached to the end ( ) of the filler neck using a thread ( ) or bayonet, and a seal ( ) whose sealing surface ( ) faces a counter-sealing surface ( ) of the filler neck, whereby a ring-shaped molding ( ) is provided between the sealing surface and the counter-sealing surface. In order to minimize the amount of permeation, a sealing ring ( ) outside of the molding ( ) is provided, the sealing ring being made of an elastomer with high resistance to permeation, and the sealing surface ( ) and the counter-sealing surface ( ) create a narrow gap ( ) on the sealing ring ( ) side facing the molding ( ), this gap extending to the sealing ring ( ).
