Castellated Silicone Hoses (CSH / Superflex Hoses)

Castellated silicone hoses are designed for applications requiring maximum flexibility without compromising strength or performance.

Featuring a unique castellated (ribbed) outer profile, these hoses provide enhanced bend radius capability, making them ideal for tight installations and complex routing where standard hoses would kink or fail.

  • Superflex design for tight bend applications
  • Castellated profile for enhanced flexibility
  • Maintains strength under pressure
  • Ideal for complex routing and restricted spaces

Castellated silicone hoses (CSH hoses), also known as Superflex hoses, are specialist silicone hoses engineered with a ribbed or castellated outer construction.

This design allows the hose to:

  • Bend more easily without kinking
  • Maintain airflow and structural integrity
  • Perform reliably in confined or complex installations

They are particularly suited to applications where space is limited and flexibility is critical.

  • Known As

    • Superflex hoses
    • Castellated hoses
    • Flexible silicone hoses
    • Anti-kink silicone hose
    • Ribbed silicone hose
    • CSH

  • Key Features and Benefits

    Enhanced Flexibility (Superflex Design) – Allows tighter bend radii compared to standard silicone hoses.

    Anti-Kink Performance – Maintains internal flow by preventing collapse or restriction during bending.

    Durable Construction – Reinforced silicone ensures strength under pressure and long-term use.

    Reliable Air & Fluid Transfer – Maintains consistent performance even in complex routing conditions.

    Versatile Application Use – Suitable for a wide range of automotive, industrial, and engineering systems.

  • What CSH Hoses Are Used For

    Castellated silicone hoses are used in applications where flexibility and routing are critical:

    • Automotive engine bays with tight space constraints
    • Turbocharger and intake systems
    • Charge air and cooling systems
    • Marine and rail installations
    • Industrial machinery and equipment
    • Custom and bespoke hose solutions

  • Sizes, Lengths, Angles

    • Inner diameters (ID): From 6mm to 76mm
    • Straight: Available as standard in 1, 2, 3 and 4 metre lengths. Other lengths can be requested.
    • External colours: Full range of colours available upon request.

Why Castellated / Superflex Hoses Are Required

In many systems, especially in automotive and industrial environments, hoses must navigate:

  • Tight spaces
  • Complex routing paths
  • Sharp bends and angles

Standard silicone hoses can:

  • Kink under tight bends
  • Restrict airflow or fluid transfer
  • Experience premature wear or failure

Castellated hoses are engineered to:

  • Provide enhanced flexibility and bend capability
  • Prevent kinking and flow restriction
  • Maintain performance in challenging installations
