Fire hose is a high-pressure hose that carries water or other fire retardant (such as foam) to extinguish a fire. Outdoors, it attaches either to a fire engine or a fire hydrant. Indoors, it can be found in fire cabinet or permanently attach to a building's standpipe or plumbing system. The usual working pressure of a firehose can vary between 10 and 28 bar or 150 and 400 psi while per the NFPA 1961 Fire Hose Standard, its bursting pressure is in excess of 110 bar or 1600psi. Hoses are divided into two categories, based on their use: suction hose, and delivery hose.

Modern fire hoses use a variety of natural and synthetic fabrics and elastomers in their construction. These materials allow the hoses to be stored wet without rotting and to resist the damaging effects of exposure to sunlight and chemicals. Typical materials of lining are EPDM, PU, TPU, PVC or rubber. Nowadays fire hose manufacturers use Polyester or Nylon to made woven jacket to protect the lining. Some fire hoses are even covered by rubber or plastic to increase abrasion resistance.
