5-inch (13 cm) flex suction hose with Storz fittings, mounted on an engine. Flexible suction hose (Flex suction or suction hose), not to be confused with hard suction hose in U.S., is a specific type of fire hose used in drafting operations, when a fire engine uses a vacuum to draw water from a portable water tank, pool, or other static water source.
Attack hose is a fabric-covered, flexible hose used to bring water from the fire pumper to the nozzle. This hose ranges in nominal inside diameter from 1.5 to 3 in (38 to 76 mm) and is designed to operate at pressures up to about 400 psi (2,760 kPa). The standard length is 50 ft (15.24 m).

Hard suction hose A flexible rubber hose reinforced with a steel core to prevent collapse from atmospheric pressure when drafting; connected between the intake of a fire pump and a water supply and must be used when drafting. Also called hard hose, hard sleeve, or hard intake/suction hose. [5] Helmet
1-inch hose with 1-8 NH NFPA threads (NFPA 1963 requirement; a.k.a. "Chemical Hose Thread" and "Booster Hose Thread"; the chemical hose thread term likely originates from its use on chemical fire engines, an early firefighting device used from 1872 until the 1930s that used a combination of bicarbonate of soda and sulfuric acid to force water ...
To reduce drafting friction and obtain a larger flow or higher lift, a larger cross-section of suction hose is employed. For example, using a five-inch (127 mm) hose, a pump that could lift 500 US gallons per minute (30 L/s) up 23 feet (7.0 m) would only be able to lift the same amount of water 12.5 feet (3.8 m) through a 3.5-inch (89 mm) hose.
The 100 mm (4-inch) and 125 mm (5-inch) Storz couplers have been specified in NFPA 1963, Standard for Fire Hose Connections, since the 1993 edition. U.S. cities that have fire hydrants with 125 mm Storz connectors include Raleigh, NC [ 5 ] and the City of Corvallis, OR (adapter on 4-inch threaded outlet).
