This pumpout adapter provides the most secure connection of pumpout hose to boat by using a quick clamp adapter (1.5" Male Quick Clamp X 1.25" Male NPT) and flat sealing washers. The male thread end of an adapter is screwed into the boat waste deck fitting and the pump out hose, equipped with a 1.5" quick clamp female adapter, is then clamped into place. Used on boats with waste deck fitting caps of 1.25" thread.
