Plastic tubes are used in automotive fuel systems

Plastic tubes are now commonly used in automotive fuel systems. They are used for the passage of fuel (liquid or gas) and are mainly located in the piping around fuel tanks. They can be used for vapour tubes, in-tank fuel delivery, and underfloor piping.

Plastic tubes are also used for fuel lines, battery cooling, breather vent pipes, and washer fluid lines. They are a good alternative to rubber hoses as they are flexible, recyclable, and offer longevity. They also contribute to improved fuel efficiency due to their lightweight nature.

There are various types of plastic tubes available, including single and multi-layered tubes made of nylon, polyethylene, acrylic, plexiglass, and polycarbonate. These tubes can be cut to size and are available in a range of colours.

In recent years, there has been an increasing demand for conductive automotive fuel lines due to safety reasons. The use of conductive plastic tubes for feed and return lines is becoming essential for car manufacturers worldwide.

Conductive fuel lines are designed to prevent the build-up of static electricity caused by the flow of hydrocarbon and other non-polar liquids over plastics. These lines typically have an innermost layer made of conductive materials such as polyamide (PA) 12, EFFE, and EFEP.

Plastic tubing protects wires, cables and hoses

Plastic tubing is an essential component in automobiles, providing protection for wires, cables, and hoses. It offers a range of benefits that ensure optimal vehicle performance and safety. The use of plastic tubing in automotive fuel systems has expanded due to its versatility and durability.

Plastic tubing comes in various sizes, typically ranging from 1/4" to 3-1/2", to accommodate different automotive applications. One of its primary functions is to protect wires, cables, and hoses from mechanical abuse and external elements. This includes safeguarding against extreme temperatures, moisture, abrasion, and corrosion, which can cause damage over time.

The flexibility of plastic tubing is a notable advantage. It can bend and flex without losing its strength, allowing it to adapt seamlessly to the contours of cables and hoses. This flexibility also makes installation easier, as the tubing can be slit down the middle, simplifying the process of inserting wires and cables.

Plastic tubing also offers chemical resistance, which is crucial in the automotive environment where exposure to various fluids, such as gasoline, oil, and other chemicals, is common. Additionally, plastic tubing provides electrical and mechanical protection, ensuring that wires and cables are safely encased, minimising electromagnetic interference, and protecting against potential fire hazards.

The use of plastic tubing in wire protection and organisation goes beyond automobiles. It is also valuable in electronics, telecommunications, construction, agriculture, and marine environments, where it helps manage intricate cable setups and protects against challenging conditions, such as saltwater corrosion. Overall, plastic tubing plays a vital role in maintaining the reliability and safety of various systems by protecting and organising wires, cables, and hoses.

Plastic tubes are used in air and water delivery systems

Plastic tubes are used in a variety of automotive systems, including air and water delivery systems. These tubes are tailored to meet the exact specifications required for various automotive applications, offering several benefits over traditional metal or rubber alternatives.

One of the key advantages of plastic tubing is its lightweight nature, which helps to improve fuel efficiency and reduce carbon emissions. Plastic tubing achieves this by replacing heavier metal pipes, contributing to overall vehicle weight reduction. Plastic tubes are also highly resistant to corrosion, ensuring long-lasting and reliable fluid flow.

Plastic tubing is commonly used in fluid transport systems, such as brake lines, fuel lines, coolant systems, and power steering systems. It is also used in air intake systems, where it helps route air from the intake manifold to the engine, optimizing combustion and reducing emissions.

Additionally, plastic tubing plays a crucial role in HVAC (heating, ventilation, and air conditioning) systems. Its resistance to extreme temperatures makes it ideal for transporting refrigerants and air within these systems, ensuring their effectiveness even in harsh weather conditions. The flexibility of plastic tubing allows for easy routing within the complex and confined spaces of modern vehicles.

Plastic tubes for automotive applications are available in various materials, such as nylon, polyethylene, acrylic, polycarbonate, and thermoplastic. They come in different sizes, typically ranging from 1/4" to 3-1/2", and can be customized to meet specific requirements.

Plastic tubes are available in different colours

Plastic tubes are used in cars for fuel systems, air and water delivery systems, and to protect wires, cables, and hoses. They are available in a variety of sizes, typically ranging from 1/4" to 3-1/2".

Acme Plastics, for example, offers acrylic tubes in various colours and opacities, while also carrying engineering plastic tubes in different materials. Freelin-Wade specializes in coloured poly, PVC, and vinyl tubing, offering transparent, coloured, and neon options in multiple colours and sizes. Their customization process involves submitting a colour swatch or contacting a sales representative to create coloured tubing that meets specific requirements.

In addition to colour, plastic tubes can be made from different materials such as HDPE, polycarbonate, nylon, PEEK, PES, and UHMW. These materials offer varying characteristics, making them suitable for specific applications. For instance, nylon split loom tubing is ideal for automotive wire protection due to its resistance to abrasion, gasoline, and other chemicals.

When choosing plastic tubes for cars, it is important to consider not only the colour but also the specific application and performance requirements. This includes factors such as temperature extremes, fluid handling, and chemical resistance, which will determine the most suitable type of plastic tube for the job.
