FM200 Flexible Discharge Hose
by:admin October 22, 2025 0 Comments

FM200 Flexible Discharge Hose offers a safe and efficient solution for connecting a 140L FM-200 cylinder to the main discharge pipe or manifold. Designed for durability and compliance with TCVN 7161-1, this hose ensures proper operation in fire suppression systems with multiple cylinders.

This product, coded SFS-FC50, comes from Vietnam and reflects a high standard of local fire safety equipment manufacturing.


Main Features

  • Durable Stainless Steel Mesh Cover protects the hose from corrosion and mechanical damage.
  • Built-in Check Valve stops gas backflow when a cylinder is removed for service.
  • Easy-to-Install Design supports both straight and 90° curved installations.
  • Weld Fittings Included for secure integration with existing piping systems.

What Makes This Product Essential

When using more than one FM-200 cylinder connected to a common manifold, the use of check valves becomes mandatory. According to Clause 6.2.4.4 of TCVN 7161-1, each cylinder must include a check valve to prevent the unintentional loss of agent during servicing.

This flexible hose with a check valve ensures that your fire suppression system remains sealed and operational—even when technicians disconnect one cylinder for maintenance. Therefore, you avoid gas loss and maintain compliance with fire safety regulations.
