Abstract
A channel-shaped sealing strip for mounting on a flange, for example around a door or window opening in a motor vehicle body, comprises a channel-shaped metal core or carrier. On to one wall of the channel, relatively hard flexible material, such as plastics, is directly extruded, while on to the other side wall of the channel relatively softer material, such as rubber, is directly extruded, the relatively hard material extending over the outside surface of the carrier to meet the relatively softer material. The relatively softer material is extruded integrally with an external sealing bead running along the sealing strip. The flexible material may extend over part or all of the inside surface of the carrier member.
