Hose and Flexible Tubing
FSC 4720: Hose and Flexible Tubing
Federal Supply Class (FSC) 4720 covers hose and flexible tubing. These NSN items carry fluids and gases where flexibility is needed.
Flexible hose conveys fluids and gases between moving or offset connections. It is essential where rigid pipe cannot be used.
Common items include hydraulic, fuel, air, and water hose. Hoses use rubber and synthetic compounds with reinforcing braids.
