What You'll Learn
Nickel-copper tubing is easy to bend and flare
Copper-nickel tubing, also known as Cupronickel tubing, is the preferred choice for shops and DIY customers when replacing brake and fuel lines. This is because it is easy to bend and flare, and it won't rust over time like regular steel tubes.
Nickel-copper tubing is available in various forms to cater to different installation preferences and projects. For flexibility and ease of handling, you can opt for coiled tubing. If you have specific routing requirements, straight-line tubing might be the better option. A comprehensive kit that includes various lengths and fittings is also usually available if you need more options.
The ease of bending and flaring copper-nickel tubing makes it a popular choice for those looking to replace their brake and fuel lines. This tubing will not rust and is available with or without fittings and gravel guard spring kits.
Copper-nickel brake and fuel line tubing kits come in various sizes and configurations, such as 25-foot rolls with standard fittings and tube cutters or packs of three 33-inch pieces with inverted double flares and standard tube nuts. You can also find copper-nickel fuel/transmission line coils with a 1/2" O.D. tube.

It is DOT-approved for fuel and brake lines
Copper-nickel tubing is a popular choice for auto enthusiasts, especially those who enjoy DIY car projects. It is a versatile material that can be used for fuel and brake lines, and it offers several advantages over traditional steel tubing. One of its key benefits is that it is DOT-approved for fuel and brake lines. This approval is a mark of its safety and reliability for on-road vehicles.
The tubing is made from a copper-nickel alloy, which is known for its durability and resistance to corrosion. This is a significant improvement over steel, which is prone to rusting over time. The corrosion-resistant properties of copper-nickel tubing ensure that it will not rust, neither on the inside nor the outside, providing long-lasting performance for car owners. This feature also eliminates the need for expensive fittings, as simple brass flare fittings can be used instead.
Copper-nickel tubing is also much easier to work with than steel. It is highly flexible and can be easily bent by hand, making it simple to route and install, even in tight spaces. This flexibility reduces the need for specialized tools and equipment during installation, making it a cost-effective option. The tubing can be purchased in various forms, including coiled tubing for maximum flexibility and straight-line tubing for specific routing requirements.
In addition to its ease of use, copper-nickel tubing is also known for its ability to create strong flare fittings. The soft metal of the tubing allows for the creation of double flare fittings, which provide secure connections in fuel and brake lines. However, it is important to exercise caution when tightening joints to avoid over-tightening due to the softness of the metal. Copper-nickel tubing's combination of flexibility, corrosion resistance, and strong flare fittings make it a preferred choice for car enthusiasts looking for a reliable and easy-to-use solution for their fuel and brake line needs.

It is available in multiple forms to cater to different installation preferences
Nickel-copper tubing is available in multiple forms to cater to different installation preferences. This versatility makes it a popular choice for both professionals and DIY enthusiasts when replacing brake and fuel lines.
For those who prioritise flexibility and ease of handling, coiled tubing is an ideal option. Straight-line tubing, on the other hand, is perfect for those with specific routing requirements. If you're looking for a more comprehensive solution, you can opt for a kit that includes various lengths and fittings, ensuring you have everything you need for your project.
The ease of bending nickel-copper tubing makes it a popular choice for fuel lines. It can be easily manipulated to fit into tight spaces and bent by hand without creasing, simplifying the installation process. This is especially useful when working around corners or through crevices, as the tubing can be pushed through without the need for complex tools.
Nickel-copper tubing is also known for its corrosion resistance. Unlike steel tubing, it will not rust over time, ensuring the longevity of your fuel lines. This feature, combined with its flexibility, makes it a superior choice to stainless steel tubing, which can be more challenging to work with and may require expensive tools for flaring.
In addition to its durability and ease of use, nickel-copper tubing is cost-effective. You can save money by installing it yourself and opting for compression fittings instead of purchasing a kit. This makes it an excellent option for those on a budget who still want a reliable and long-lasting fuel line solution.

It is more corrosion-resistant than stainless steel
Copper-nickel alloys are commonly used in marine and offshore applications, heat exchangers, and electrical equipment. They are highly resistant to corrosion, especially in saltwater and high-humidity environments, making them ideal for use in coastal areas. This resistance to corrosion is due to the blend of copper and nickel, with nickel content typically ranging from 10% to 30%. The nickel content gives copper-nickel alloys their desirable properties, making them effective in harsh conditions.
In contrast, stainless steel is a steel alloy composed of chromium, nickel, and other elements. While stainless steel is known for its strength, corrosion resistance, and ductility, it is not as resistant to seawater corrosion as copper-nickel alloys. Stainless steel is commonly used in applications that require high levels of resistance to harsh chemicals and acids, such as medical equipment, automotive parts, and aerospace. It is also a popular choice for kitchen tools, building materials, and car parts due to its durability and aesthetic appeal.
The exceptional corrosion resistance of copper-nickel alloys in seawater makes them a preferred choice for marine applications. They are highly effective in preventing the rapid deterioration of metals exposed to seawater. In addition, copper-nickel alloys are more malleable and ductile than stainless steel, making them easier to bend and form. This malleability is advantageous for custom fittings and components.
While stainless steel is known for its resistance to rust, it still requires regular cleaning to maintain its shiny appearance. On the other hand, copper-nickel alloys may need more frequent maintenance and care to preserve their finish and performance, including periodic cleaning and inspection to prevent tarnishing. However, copper-nickel alloys are generally more expensive than stainless steel, which can impact the overall cost of a project.

It is a durable and cost-effective option
Nickel-copper alloy tubing is a durable and cost-effective option for fuel lines. It is DOT-approved and will not rust, ensuring long-lasting performance. Its flexibility and ease of handling make it a popular choice for both shops and DIY customers. The tubing can be easily bent by hand, eliminating the need for expensive bending tools. This quality also simplifies the installation process, allowing for routing through crevices and corners without creasing.
Nickel-copper tubing is available in various forms, including coiled tubing for flexibility and straight-line tubing for specific routing requirements. It is also offered in comprehensive kits that include various lengths and fittings to cater to different installation preferences and projects. The ease of bending makes it ideal for creating custom fuel line setups, as it can be manipulated to run from the rear of a car to the front engine bay in a single hardline.
The alloy's composition of 90% copper and 10% nickel contributes to its durability and resistance to cracking. Copper-nickel tubing is also non-magnetic and highly corrosion-resistant, ensuring its longevity in fuel delivery systems. This corrosion resistance eliminates the need for expensive fittings, as simple brass flare fittings can be used instead.
In terms of cost-effectiveness, nickel-copper tubing offers a good balance between price and performance. While stainless steel is a durable option, it tends to be more expensive and challenging to work with. Rubber or braided hoses are more affordable but less long-lasting. Nickel-copper tubing strikes a middle ground, providing durability and ease of use at a more reasonable price point.
