M.POWER Tools supplies three sizes of vacuum clamping gasket material. They all come with self-adhesive backing in rolls of 2.0 meters (6'6") in length. They are:
Template Gasket: 10mm (0.78") Wide, 3mm (0.11") Deep
Top Gasket: 20mm (0.78") Wide, 3mm (0.11") Deep
Bottom Gasket: 25mm (0.78") Wide, 6mm (0.23") Deep
Top Gasket is the standard gasket material used on the upper side of all the Mach work beds. To enlarge an existing U-Mach or Big Mach kit you will require additional Top Gasket and Bottom Gasket.
Bottom Gasket is wider and deeper than the other gasket materials. It is stronger and more durable and ideally suited to the underside which often see more 'abuse' and hard knocks.
Template Gasket is thinner than the other gaskets. This allows it to be curved more easily whilst maintaining its form and is thus very suitable for templates where curves and arcs will often be required.
The gasket material is closed-cell expanded neoprene/EPDM polymer blend sponge rubber. It is durable, oil and ozone resistant, fire retardant with a density of 96 kg/m². What does this mean? Well the density and compression properties of the gasket rubber mean it is strong enough to securely hold the workpiece in place for woodwork machining whilst still having enough give to form an ideal contact seal with any flat and smooth workpiece placed on it. The gasket is fairly robust and if it is looked after it will last a long time. Should any of the gasket material on any of the Mach work beds get damaged the supplied repair patch can be used to replace the damaged section.
