In order to ensure that a seal is secured into a groove of a component or part onto which the seal is mounted the seal profile is provided with a resilient lip . This lip creates friction forces against the sides of a groove so as to retain the seal therein. This design allows unintentional interruptions in the lip without risking the friction-based retention of the seal in the groove. Also various imperfections in the groove are acceptable, since the resilient lip will adapt thereto. Moreover, the seal is relatively insensitive to variations in the overall width of the groove. The seal may be used in an internal combustion engine as a seal between an oil pan and an engine block.
