Extruded Silicone Hoses (SHH / Heater Hoses)

Extruded silicone hoses are designed for continuous lengths and uniform profiles, making them ideal for heater, coolant, and low-pressure fluid transfer applications.

Manufactured using a precision extrusion process, these hoses offer consistent wall thickness, flexibility, and reliable performance, particularly in systems where long runs and custom lengths are required.

  • Continuous lengths for flexible installation
  • Ideal for heater and coolant systems
  • Consistent profile and wall thickness
  • Durable and heat resistant construction

Extruded silicone hoses (SHH hoses), commonly referred to as heater hoses, are manufactured through an extrusion process, producing continuous lengths of hose with a consistent cross-section.

This makes them ideal for:

  • Straight runs and long installations
  • Applications requiring flexible routing
  • Systems where consistent diameter and performance are important

They are widely used in heating, cooling, and general fluid transfer systems.

  • Known As

    • SHH
    • Extruded silicone hose
    • Heater hoses
    • Silicone heater hose
    • Continuous silicone hose

  • Key Features and Benefits

    Continuous Lengths – Supplied in long runs, allowing for flexible installation and reduced jointing.

    Consistent Wall Thickness – Ensures uniform performance and reliability across the hose.

    Heat Resistance – Suitable for applications requiring resistance to elevated temperatures.

    Flexible and Easy to Install – Ideal for routing through complex systems without the need for multiple connections.

    Cost-Effective Solution – Efficient for applications where moulded hoses are not required.

  • What SHH Hoses Are Used For

    Extruded silicone hoses are used across industries where heater and coolant systems require flexible, continuous hose solutions:

    • Automotive heater and coolant systems
    • Commercial vehicles and heavy-duty fleets
    • Marine cooling systems
    • Rail and transport systems
    • Industrial machinery and equipment
    • General fluid transfer applications

  • Sizes, Lengths, Angles

    • Inner diameters (ID): From 6mm to 32mm
    • Straight: Available in up to 25 metre coils.
    • Colours: Blue for standard silicone, Kawasaki Green for OAT silicone heater hose.

Why Extruded / Heater Hoses Are Required

In many applications, particularly in automotive and industrial systems, there is a need for:

  • Long, continuous hose runs
  • Flexible routing without complex moulded shapes
  • Reliable performance at moderate pressure levels

Extruded hoses are designed to:

  • Provide cost-effective and efficient solutions for long runs
  • Maintain consistent performance across the entire length
  • Offer flexibility and ease of installation

This makes them ideal for heater and coolant systems, where uniformity and reliability are key.
