US Patent 7464972 Air evacuation attachment for fire hoses

An air evacuation attachment for a fire hose includes an elongated conduit having an inlet and an opposing outlet. At the inlet is a Storz adaptor for coupling the conduit with a fire hose having a predetermined diameter. Storage tubes are provided along the length of the conduit each having a varying size Storz adaptor mounted thereon for interchangeably securing to the inlet to adapt the conduit to varying size fire hoses. The outlet includes internally disposed O-rings for tightly encompassing a vacuum hose. Accordingly, a fire hose can be conveniently connected to a vacuum source to remove excess air therefrom prior to storage.
