Abstract
A ventilation nipple configured to ventilate a tank component that is composed of a plastic material, a tank device that includes such a ventilation nipple, and a method for producing such a tank device. The ventilation nipple includes a ventilation opening and a flange body arranged in an annular manner around the ventilation opening. The flange body has a first annular collar and a second annular collar each configured for connection via a weld connection to the tank component. The first annular collar and the second annular collar are arranged coaxially with respect to each other and also with respect to the ventilation opening. The first annular collar and the second annular collar define an annular hollow space configured to receive a sealing agent and/or an adhesive between the first annular collar and the second annular collar.
