Silicone Hoses (Standard / VMQ / Universal Hoses)

Silicone hoses are versatile, high-performance solutions designed for coolant, air, and fluid transfer across a wide range of applications.

Manufactured from VMQ (Vinyl Methyl Silicone), these hoses offer excellent temperature resistance, flexibility, and durability, making them ideal for radiator systems, cooling circuits, and general-purpose use.

Universal silicone hose for multiple applications
Excellent temperature resistance (-60°C to +180°C+)
Flexible, durable, and long-lasting
Suitable for coolant, radiator and air systems

What are Silicone Hoses?

Silicone hoses (also known as standard or universal hoses) are manufactured using VMQ silicone rubber, a material widely recognised for its thermal stability, flexibility, and resistance to environmental factors.

They are commonly used in systems where high temperature performance and reliability are required, particularly in cooling and air transfer applications.

  • Key Features and Benefits

    Wide Temperature Range – Typically operates between -60°C and +180°C, with higher performance available depending on construction.

    Excellent Thermal Stability – Maintains mechanical properties under prolonged heat exposure.

    UV, Ozone & Weather Resistance – Ideal for both internal and external applications where environmental exposure is a factor.

    Flexible and Durable – Retains flexibility across extreme conditions, reducing risk of cracking or failure.

    Reliable Performance – Suitable for continuous use in cooling and air systems.

  • What SH Hoses Are Used For

    Silicone hoses are widely used across industries due to their flexibility and performance:

    • Automotive radiator and coolant systems
    • Air intake and charge air systems
    • Marine cooling systems
    • Rail and heavy-duty vehicle applications
    • Industrial machinery and equipment
    • General fluid transfer applications

  • 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.
    • External colours: Blue is the standard colour. Our full range of colours is available upon request.

Why Silicone Hoses Are Used

Compared to traditional rubber hoses, silicone hoses offer significant advantages in demanding environments.

They are designed to:

  • Withstand high and low temperatures
  • Maintain flexibility without cracking or hardening
  • Resist UV, ozone, and weathering
  • Deliver long-term durability in engine and industrial systems

This makes them a preferred solution for applications where consistent performance and longevity are essential.

Leyland Hose & Silicone Capability

At Leyland Hose & Silicone, our silicone hoses are:

  • Manufactured using high-quality VMQ compounds
  • Available in various diameters, shapes, and reinforced constructions
  • Designed for consistent performance under heat and pressure
  • Suitable for both standard and bespoke applications

Our hoses deliver reliable, long-lasting performance across multiple industries.

Silicone Hose vs Specialist Hoses

While silicone hoses are highly versatile, they are designed for general-purpose applications:

  • Standard Silicone (VMQ / SH) – Coolant, radiator, and air systems
  • OAT hoses – Designed for organic acid coolant systems (Euro 6)
  • Fluorosilicone hoses (FVMQ) – Designed for fuel and oil resistance

This makes standard silicone hoses the go-to solution for general cooling and airflow applications, where specialist chemical resistance is not required.
