This Semi-rigid hose is used as part of a hose reel system.
Typically (but not exclusively) red in colour, round in section. The purpose of this type of hose is to provide a steady flow of water quickly as a first response in a fire situation, without having to set up length of hose from another source. The semi-rigid construction helps to prevent kinks which would restrict supply. It is durable and
operates in a fairly wide temperature range
