Abstract
A bezel and bezel assembly in which the bezel is a rigid block with a plurality of cavities. A depression in the block has ribs extending up therefrom to form an elevated contour. The depression includes at least one cavity therein for the application of air pressure into the depression and over the elevated contour. A gasket fits over the bezel so that positive pressure applied through the at least one cavity in the depression forces a gasket membrane to expand away from the pumping side and negative pressure applied through the at least one cavity in the depression pulls the gasket membrane against the elevated contour of the ribs. The bezel may include solvent bondable tubing connections for making pneumatic connections to the bezel.
