Abstract: An improved hose coupling is disclosed. The coupling is comprised of a fitting and a ferrule to be radially crimped about the end of the fitting, securing a hose end. The coupling is provided with an extension against which the hose end abuts prior to crimping of the coupling. The extension also enables the hose material to flow axially during crimping.

Abstract: The present invention is directed towards a dust plug for insertion into a fluid conduit system. The dust plug is comprised of an insertion end, removal means, and a hollow central body located between the insertion end and the removal means. The insertion end 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 about the end of the hollow central body.
