Silicone hoses are essential in automotive, industrial, and motorsport applications due to their superior durability and high-temperature resistance. Below are answers to frequently asked questions about silicone hoses, including information on specialised products like Profuel hoses. 

1.     What are the benefits of silicone hoses compared to rubber hoses?

Silicone hoses offer superior flexibility, durability, and resistance to extreme temperatures compared to rubber hoses. Over time, rubber hoses are more likely to degrade, crack, or become brittle, while silicone maintains its structure and flexibility. Silicone hoses also handle higher pressure and temperature ranges, making them ideal for performance and racing applications. Their customizable appearance, available in a variety of colours, is an additional bonus for enthusiasts.

2.     Are silicone hoses compatible with all fluids?

Standard silicone hoses are compatible with air, water, and coolant but are not suitable for oil, fuel, or other petroleum-based fluids due to chemical incompatibility. For these applications, specialised hoses are necessary:

 

  • Samco Sport Profuel Hoses: Profuel hoses are a specialised solution for applications requiring direct and prolonged exposure to fuels, oils, and other aggressive chemicals. These hoses are built specifically for high-performance scenarios, such as non-pressurised fuel delivery systems, ensuring reliable operation without degradation.
  • Samco Sport Fluorolined Silicone Hoses: Designed with a chemical-resistant inner layer, these are suitable for contact with oils, diesel and other hydrocarbons.
 

Selecting the appropriate hose type for the application ensures longevity and performance.

3.     How do you install silicone hoses correctly?

To ensure a proper seal and optimal performance, follow these installation steps:

 

1.     Prepare the Surface: Clean all pipework and fittings to remove dirt, grease, and debris.

2.   Match and Align: Replace one hose at a time, ensuring the new silicone hose matches the original in size and orientation.

3.   Fitting and Clamping: Use non-perforated hose clamps to secure the hose. Samco Sport recommends using corresponding clamp kits, which are designed to avoid damage to silicone materials during installation. Proper clamping prevents leaks and ensures the hose remains secure under pressure.

 

Incorrect clamping or improper installation may lead to premature wear or void the warranty.

4.     Can silicone hoses stretch during installation?

Silicone hoses allow for slight stretching, depending on the hose’s diameter and material construction. While this provides some flexibility during installation, over-stretching the hose can weaken the structure. Always use the correct hose size for the application to avoid compromising performance and reliability.

5.     What are Profuel hoses, and when should they be used?

Profuel hoses are engineered specifically for use in systems requiring direct exposure to fuels and oil. Unlike standard silicone hoses, which are unsuitable for prolonged fuel or oil contact, Profuel hoses incorporate lined materials designed to resist chemical degradation. These hoses are ideal for non-pressurised fuel systems, oil return lines, and other high-performance applications in motorsport or industrial settings.

 

Samco Sport Fluorolined hoses work similarly. These are designed for applications where exposure to oil, diesel or other hydrocarbons are present. 

6.     Are silicone hoses suitable for high-temperature applications?

High-quality silicone hoses, like those from Samco Sport, can tolerate extreme temperatures, typically ranging from -50°C to +180°C. For specialised applications requiring even greater heat resistance, custom options are available. This makes silicone hoses an ideal choice for turbocharged engines, racing vehicles, and other applications where thermal durability is critical.

7.     What is the difference between Race Fit and OEM replacement silicone hoses?

Race Fit silicone hoses are designed for high-performance environments, offering enhanced thermal resistance, durability, and pressure handling. These are often used in motorsport applications. OEM replacement hoses are manufactured to replicate the size and fit of the original equipment while providing improved performance and reliability. While both types deliver significant benefits, Race Fit hoses are optimised for demanding use cases, whereas OEM hoses offer a direct upgrade for standard vehicles.

8.     Can silicone hoses be customised for specific applications?

Silicone hoses can be customised to meet the needs of specific industries and applications. Customisation options include unique shapes, additional reinforcement layers, and material upgrades like fluorolining or Profuel technology. These options allow for optimised performance in challenging environments, such as chemical processing, motorsport, and high-performance automotive systems.

9.     Are silicone hoses suitable for cars and motorcycles?

Silicone hoses are widely used in both automotive and motorcycle applications due to their ability to handle high pressure, extreme temperatures, and the demands of modern engines. Manufacturers like Samco Sport provide silicone hose kits tailored for specific vehicle models, ensuring a precise fit and compatibility.

10.     How should silicone hoses be maintained?

To maximise the lifespan of silicone hoses, routine inspections should be performed to check for wear or damage. Cleaning with mild soap and water prevents the build-up of debris and contaminants that could degrade the hose surface. Avoid exposing hoses to sharp edges or excessive bending, as this could lead to unnecessary wear. Proper care ensures the hoses continue to perform reliably under demanding conditions.

 

 

Silicone hoses offer a durable, high-performance solution for a wide range of automotive, industrial, and motorsport applications. Their flexibility, temperature resistance, and long lifespan make them a reliable choice over traditional rubber hoses. By selecting the right hose type, ensuring correct installation, and following proper maintenance practices, you can maximise performance and longevity.
