Double Jacket Fire Hose Structure:
Lining: PVC,PU, Rubber lining
Cover: Double Polyester jacket
Compared with single jacket fire hose, double jacket fire hose has 2 layers of polyester jacket cover the lining. The inner jacket is a material which provide a water-tight seal. Besides, it helps prevent kinking. While the outer layer is strong and wear resistant. Between the double layers, there is a lining which can be PVC, rubber or PU. It serves as barrier against water and prevent the hose from leaking. The lining can also resist heat, chemical and wear.
Double layer design makes the hose can bear higher pressure than the single layer hose. While the working pressure can be max 400 psi. In addition, the hose is light in weight and flexible. Thus it’s very easy to handle. The hose is also less likely to kink or twist. Thus you never have to worry about the constant water supply during the use.
The lining, especially PU lining can bear high pressure up to 90℃. Thus it’s perfect for fire fighting because it will not melt or catch fire.
