Abstract: A seal for a tub/drum assembly has a ring body to secure the seal to the tub/drum assembly. An arm extends from the ring body. The arm reduces a gap between the tub and drum. A mass at an end of the arm. The mass enables the arm to deflect at high drum rotational speeds increasing the gap between the tub and drum during high rotational speed of the drum. Alternatively, the arm is of a material prohibiting substantial deflection so that the gap is maintained at all speeds between the tub and drum without the arm contacting the drum creating high resistance in an airflow path.
