Abstract
A molded tool casing of at least two sections for air-tightly encasing a tool is taught. A seal is inserted into a groove molded into the sealing perimeter of one section. A protruding ridge is molded into the sealing perimeter of a second section that is to be joined to the first casing section is adapted for compressing the seal into the groove providing for an air-tight seal for the two joined sections. The casing sections are contoured to provide air-tightly sealable inner-casing compartments for receiving and encasing tool components. Opposing joining perimeters of the air-tightly sealable compartments are adapted with the grooves and protruding ridges, respectively. The tool casing houses a tool, such as a pneumatic tool, such as a central or self-generating vacuum pneumatic tool, or a non-vacuum tool. The tool casing is molded to have a firm inner layer coated by an outer pliant overmolded layer.
