Railsil Hoses (LSLT / Low Smoke Low Toxic Hoses)

Railsil hoses are specialist silicone hoses engineered for applications requiring low smoke and low toxicity performance in the event of fire, making them ideal for rail and public transport environments.

Designed to meet strict safety standards, these hoses provide reliable performance under normal conditions, while minimising smoke emission and toxic gas release in fire scenarios.

  • Low smoke and low toxicity properties
  • Designed for rail and safety-critical environments
  • High temperature and durability performance
  • Ideal for public transport and enclosed systems

Railsil hoses (LSLT hoses) are advanced silicone hoses developed to meet low smoke, low toxicity (LSLT) requirements, particularly in environments where passenger safety is critical.

They are manufactured using specialist silicone compounds designed to:

  • Minimise smoke generation in the event of fire
  • Reduce the release of toxic gases
  • Maintain structural integrity under high temperatures

These properties make them essential for rail, transport, and enclosed public environments.

  • What LSLT Hoses Are Used For

    Railsil hoses are used in environments where fire safety and low toxicity are critical:

    • Rail and underground transport systems
    • Public transport vehicles
    • Passenger vehicles and enclosed environments
    • Industrial systems requiring low smoke materials
    • Infrastructure projects with strict safety standards

  • Sizes, Lengths, Angles

    • Inner diameters (ID): From 6mm to 152mm
    • Straight: Available as standard in 1, 2, 3 and 4 metre lengths. Other lengths can be requested.
    • Elbows: 45°, 90°, 135°, 180° with leg lengths from 102mm to 250mm. Bespoke parts also available.
    • Colours: Grey is our standard colour.

Why Low Smoke Low Toxic Hoses Are Required

In confined or passenger environments such as trains, underground systems, and transport hubs, fire safety is a critical concern.

Standard hose materials can:

  • Produce dense smoke
  • Release harmful or toxic gases
  • Reduce visibility and increase risk during evacuation

Railsil hoses are engineered to:

  • Limit smoke generation
  • Reduce toxicity of emitted gases
  • Support safer evacuation conditions in fire scenarios

This makes them essential for compliance with rail and transport safety standards.
