An air handling system for a heating, ventilating, and air conditioning system comprises a housing including a sealing surface, a door wall disposed in the housing having a perimeter, and a sealing element disposed about the perimeter of the door wall. The sealing element includes a base, a stem, and a tip. The base is coupled to the perimeter of the door wall, the stem is formed between the base and the tip, and the tip is configured to selectively engage the sealing surface of the housing. A plurality of dentil features project from the stem of the sealing element and is arranged in a linear array extending parallel to the perimeter of the door wall. The array of the dentil features is configured to reduce an incidence of whistling when a flow of air passes by the tip of the sealing element.
