Description

Silicone Hump Hose is a flexible, high-performance coupling designed to absorb vibrations and slight misalignments in automotive, marine, and industrial systems. Manufactured from a smooth extruded silicone compound and reinforced with multiple layers of polyester braid, the hose delivers strength, stability, and long-lasting durability under pressure. Its distinctive hump design allows for controlled flexibility, reducing stress on pipework and components while maintaining a secure connection. Built to SAEJ20R3 standards, Silicone Hump Hose provides excellent resistance to high temperatures, ozone, and environmental ageing, making it ideal for demanding fluid, air, and coolant transfer applications. With an operating range of -50°C to +250°C, it offers consistent performance in extreme environments.

Key Features:

  • Material: Smooth extruded silicone compound with a silicone outer layer.

  • Reinforcement: 3–4 ply polyester braids for strength and pressure resistance.

  • Design: Hump profile for vibration absorption and slight misalignment compensation.

  • Operating Temperature: -50°C to +250°C.

  • Working Pressure: 2.8 bar to 5.5 bar depending on diameter.

  • Burst Pressure: 8.5 bar to 16 bar (3:1 safety factor).

  • Internal Diameter Range: 25 mm to 102 mm.

  • Wall Thickness: 4.5 mm to 5.5 mm depending on size.

  • Length: Standard 102 mm overall length.

  • Standard: SAEJ20R3 compliant.

The high-grade silicone construction ensures outstanding heat resistance, durability, and resilience against ozone and weathering, extending service life even in extreme operating environments. Polyester braid reinforcement adds dimensional stability under pressure while maintaining flexibility for installation in tight or vibrating systems. The hump design is specifically engineered to accommodate movement and vibration, reducing the risk of hose fatigue and failure over time.

Applications include automotive intercooler and turbocharger systems, marine engine connections, coolant and air transfer in performance vehicles, and industrial machinery where vibration absorption and flexibility are essential. Silicone Hump Hose provides a robust, long-lasting solution for high-temperature, high-performance fluid and air handling systems.

FREQUENTLY ASKED QUESTIONS.

Can Silicone Hoses Be Used For Fuel/Oil?

If you intend to use silicone hoses for fuel or oil applications, it is recommended to use Fluorolined Silicone, hoses are specifically designed to offer enhanced resistance to a wider range of chemicals, including fuels and oils.

Will Silicone Hose Stretch?

Silicone hoses are known for their flexibility and elasticity, which allows them to stretch to some extent. However, the degree to which a silicone hose can stretch depends on various factors, including its design, thickness, and the specific type of silicone used in its construction. We advise that our hoses can stretch a maximum of 3mm on the diameter.

Can Silicone Hoses Be Used For Coolant?

Yes, silicone hoses are commonly used for coolant applications. Silicone hoses are well-suited for coolant systems in various industries, including automotive, marine, and industrial applications.

How Long Do Silicone Hoses Last?

The lifespan of silicone hoses can vary depending on several factors, including the quality of the material, the specific formulation of the silicone, the environmental conditions, and the type of application. In general, silicone hoses are known for their durability and longevity, and they often outlast traditional rubber hoses in many applications.

What is the temperature rating of silicone hoses?

The temperature rating of silicone hoses is typically in the range of -60°C to +180°C (-76°F to 356°F). Silicone hoses are known for their ability to withstand a wide range of temperatures, making them suitable for various applications in industries such as automotive, aerospace, and manufacturing. It's important to note that specific products may have slightly different temperature ratings, so it's advisable to refer to the manufacturer's specifications for precise details on a particular silicone hose.
