发明名称 tampão contra pó ajustável.
摘要 The invention is directed towards a dust plug (10) for insertion into a fluid conduit system. The dust plug is comprised of an insertion end (14), removal means, and a hollow central body (12) located between the insertion end (14) and the removal means. The insertion end (14) of the plug is formed as a solid flat end so that when the plug is inserted into the fluid conduit system, the hollow interior of the plug does not communicate with the interior of the system. Additionally, the removal means is preferably formed as a continuous lip (16) about the end of the hollow central body (12). <IMAGE>
