Abstract: A hose apparatus used as part of an air and water supply system to deliver water and air to a firefighter. The hose apparatus includes an air hose and a water hose with an adaptor at each end of the air and water hoses. The adaptors have an inner passageway with an air groove. The adaptors have a first air hole in fluid communication with the air hose and the air groove and a second air hole in fluid communication with the air groove and the air supply or breathing hose for the firefighter. The second air hole has a coupling which prevents air from exiting the adaptors when the hose apparatus is not in use.
