Description Size: Width 25/64″ x Thickness 1/8″ x Length 78 3/4″ The Mach family of vacuum hold down work beds relies on a matrix of rubber gasket material, the Vacuum Seal Gasket Tape, to clamp boards and components. This rubber gasket matrix forms the work bed’s individual vacuum cells. Each vacuum cell has a pressure-activated ball valve at its centre and a border of rubber gasket material. The cell’s gasket border forms a contact seal against the workpiece or component over the cell. When the airflow from the vacuum source (vacuum cleaner, extractor, venturi) is actuated using the Vacuum Control Tap air is drawn from the interior of the cell and the rubber gasket material creates an airtight seals that clamps the work piece in place.
