A solid plug for insertion in the quick disconnect fitting of a hose mobile unit (a hose coiled on a hose reel) which will prevent unwanted drainage while the unit is in storage. The plug is cylindrical with a plurality of spaced annular projections designed to mate with internal surfaces within the quick disconnect fitting and with an annular elastomeric gasket at its inner end to engage with and form a seal in the end of ring or gasket the hose projecting into such quick disconnect fitting. Such plug also carries means for attaching the plug to the hose when it is not in place in such fitting.
