Abstract
A through-hull fitting for use on water-craft that allows for contained environment discharge of bilge material. The through hull fitting is a hollow tube, outwardly threaded and ribbed at the inner-hull end, and inwardly threaded at the outer hull end. A threaded lock nut is used to secure the inner-hull end against the inner hull, and the mushroom head of the outer end secures the fitting against the outer hull. The inwardly threaded portion of the fitting allows for an oppositely threaded coupling, such as that found on the male end of a standard garden hose.
