Abstract: A seal includes a housing having a back plate and a front plate. A supporting bristle layer is disposed adjacent to the back plate, and bristles in the supporting bristle layer have a first diameter. A sealing bristle layer is disposed adjacent to the supporting bristle layer, and bristles in the sealing bristle layer have a second diameter. A shielding/protecting bristle layer is disposed adjacent to the sealing bristle layer, and bristles in the shielding/protecting bristle layer have a third diameter. The second diameter is smaller than both the first diameter and the third diameter.
