Fibreglass Hoses (GLSH / High Temperature Glass Fabric Hoses)

Fibreglass hoses are engineered for applications requiring extreme heat resistance and thermal protection, where standard silicone hoses are not suitable.

Constructed using high temperature glass fabric materials, these hoses are designed to withstand continuous exposure to very high temperatures, making them ideal for exhaust systems and high-heat industrial environments.

  • Exceptional high temperature resistance
  • Designed for extreme heat environments
  • Durable and thermally stable construction
  • Ideal for exhaust and industrial applications

What are Fibreglass Hoses?

Fibreglass hoses (GLSH hoses) are specialist hoses manufactured using glass fibre fabric, designed to provide thermal insulation and protection in extreme temperature conditions.

Unlike standard silicone hoses, fibreglass hoses are specifically developed to:

  • Withstand very high continuous temperatures
  • Provide thermal shielding and insulation
  • Maintain structural integrity in harsh environments

They are commonly used in applications where heat management is critical to system performance and safety.

  • Key Features and Benefits

    Extreme Temperature Resistance – Designed to operate in environments where temperatures exceed the limits of conventional hose materials.

    Thermal Insulation Properties – Provides protection against heat transfer, helping to safeguard surrounding components.

    Durable Construction – Glass fabric construction offers strength and resistance to heat-related degradation.

    Fire and Heat Resistance – Suitable for applications where exposure to flames or extreme heat is a risk.

    Reliable Performance in Harsh Environments – Engineered for long-term use in demanding industrial and automotive systems.

  • What GLSH Hoses Are Used For

    Fibreglass hoses are widely used in applications where extreme heat resistance is required:

    • Automotive exhaust systems
    • Turbocharger and high-heat engine components
    • Marine exhaust and engine systems
    • Rail and heavy-duty vehicle applications
    • Industrial furnaces and high-temperature machinery
    • Heat shielding and insulation systems

  • Sizes, Lengths, Angles

    • Inner diameters (ID): From 6mm to 152mm
    • Straight: Available as standard in 1, 2 and 3 metre lengths. Other lengths can be requested.
    • External colours: Brick red. Other colours may be available.

Why Fibreglass Hoses Are Required

In high-temperature environments, traditional hose materials can:

  • Degrade or fail under sustained heat
  • Lose flexibility and structural integrity
  • Pose safety risks in extreme conditions

Fibreglass hoses are engineered to:

  • Withstand extreme temperatures beyond standard silicone limits
  • Provide thermal protection to surrounding components
  • Maintain performance in continuous high-heat environments

This makes them essential for systems where heat resistance and safety are critical factors.
