ABSTRACT:
A universal attachment for capturing and utilizing exhaust gas from pneumatic power tools having a conventional pressurized gas line connection and a conventional exhaust gas port, includes an inner sleeve member having at least one exhaust outlet and being configured to accommodate a conventional gas line assembly there within. An outer sleeve member is configured to accommodate the inner sleeve member there within. At least one spring is disposed between the inner sleeve member and the outer sleeve member. In use with a pneumatic power tool, the outer sleeve member is securely held against the tool by way of coupling the conventional gas line assembly, placed within the inner sleeve member, to the conventional pressurized gas line connection of the tool. In this manner, the outer sleeve member encompasses the conventional exhaust gas port of the tool such that exhaust gas from the tool is blown (i) through the outer sleeve member, (ii) through the inner sleeve member, and finally (iii) out from the exhaust outlet of the inner sleeve member, thereby harnessing the exhaust gas for a desired secondary function.
