Abstract: A seal assembly 10 includes an attachment stud 11, a reinforcing mesh 12, a rigid carrier 13, an elastomeric body 14, and an elastomeric film 15, each having a longitudinal axis 16. The carrier 13 includes an inner peripheral surface 31 defining a central opening 33 and an outer peripheral surface 32. A lateral surface 35 of the carrier 13 extends between the peripheral surfaces. Corner towers 38 and intermediate towers 39 are arranged along the outer peripheral surface 32. The towers are spaced apart by openings 40 and terminate in control surfaces 41. The body 14 includes a stationary portion 47 generally aligned with the carrier 13 and a diaphragm portion 48 generally aligned with the opening 33. The film 15 extends over and is bonded to the body portion 14 and the towers 38, 39 to provide a smooth uninterrupted chemically resistant surface for the seal assembly 10.
