A sealing strip comprises a base and pile formed on the base. The strip is sandwiched between two surfaces to form a seal between the surfaces with the base being mounted on one surface and the pile being compressed by the other surface. If the seal is improved by increasing the compression, the friction between the pile and the other surface is such that the two surfaces cannot be readily moved relatively to one another in a direction parallel to the surfaces. The sealing strip endeavours to overcome this problem by having a yarn of a lower coefficient of friction than the fibres of the pile at or above the surface of the pile. This reduces the frictional force between the pile and the other surface thus allowing easy relative movement of the surfaces when the pile is highly compressed by the other surface to form an effective seal.
