Abstract
A flexible seal (2), particularly for use in pneumatic testing of cigarettes, includes a conical seat (6) attached to a tube (4) having a resilient collar (8). The collar permits longitudinal movement of the seat relative to the tube, thereby permitting an effective seal against the cigarette being tested, and contributes to extended life for the seal.
