<p>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).</p> |
