A fire hose is a hose used to carry high-pressure water or flame retardant liquids such as foam.  Traditional fire hoses are lined with rubber and covered with linen braid.  Advanced fire hoses are made of polymeric materials such as polyurethane.  The fire hose has metal joints at both ends, which can be connected to another rubber belt, polyurethane belt, PVC fire hose root belt to extend the distance or connected to the nozzle to increase the liquid injection pressure.
