Fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. The traditional fire hose is lined with rubber, and the outer surface is wrapped with flax braid. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints on both ends of the fire hose. You can connect another rubber hose, polyurethane hose, or PVC fire hose to extend the distance or connect a nozzle to increase the liquid injection pressure.
