What You'll Learn
NiCopp is suitable for fuel lines
NiCopp is a suitable material for fuel lines. It has been used in hydraulic/fluid transfer systems on vehicles, including fuel systems. NiCopp is a copper-nickel alloy that is stronger than brass and highly corrosion-resistant. It is also more flexible than steel, making it easier to bend and work with. This flexibility may also make it more durable than steel in certain situations, such as when it needs to withstand constant flexing in one spot.
However, it is important to note that NiCopp is softer than steel, which can make it more prone to metal fatigue, especially in vibration applications like engine fuel lines. This softness also means that it may not be suitable for use with compression fittings, as the ferrules may not be able to get a tight grip on the line. To address this issue, some people have used inserts or lubrication to help keep the line from collapsing.
NiCopp is DOT-approved for fuel lines, and it has been used in Europe for this purpose since the 1970s. It is also fuel-compatible and will not react with ethanol, a common component of modern fuel.
Overall, NiCopp is a safe and effective option for fuel lines, offering advantages such as flexibility and corrosion resistance. However, it is important to consider its softness and potential issues with certain types of fittings.

NiCopp is easier to bend than steel
NiCopp, a nickel-copper alloy, is a popular alternative to steel tubing in fuel, brake, and transmission systems. It is known for its ease of use, ductility, and corrosion resistance.
NiCopp's softer composition makes it easier to bend than steel, which is harder and more challenging to manipulate. This property of NiCopp simplifies the process of installing and routing fuel lines, especially in tight or complex spaces. Its flexibility allows it to be pushed into corners and bent to fit specific requirements without the need for excessive force.
However, the softness of NiCopp can also present challenges. Some users have reported issues with compression fittings, as the ferrules may not adequately grip the soft tubing, leading to leaks. To address this, it is recommended to use inserts or hose clamps to reinforce the connection and prevent leaks.
Additionally, the ductility of NiCopp may raise concerns about its durability, particularly in vibration applications like engine fuel lines. There are worries that the material could be prone to metal fatigue and potential breaches or tears if struck by a hard object. However, these concerns are largely speculative, and the longevity of NiCopp fuel lines remains to be seen.
While NiCopp is easier to bend than steel, it is important to note that bending NiCopp tubing requires proper tools and techniques. Users have reported mixed experiences with hand benders and bending springs, with some finding success and others encountering issues like kinking or collapsing. Techniques such as filling the tube with dry sand or using lithium grease on the bender can aid in achieving the desired bends without damaging the tubing.

NiCopp is softer than steel
NiCopp, or nickel copper, is a copper-nickel alloy that is frequently used in brake lines for vehicles. It is also used in hydraulic/fluid transfer systems on vehicles where steel lines and tubing are commonly used. This includes brake, fuel, and transmission systems.
NiCopp's flexibility and softness make it ideal for use in fuel lines as it is easy to bend and will not rust out. Its corrosion resistance also makes it a good choice for long-term use. Steel, on the other hand, tends to rust quickly, giving NiCopp a unique advantage for this purpose.
While NiCopp is softer than steel, it still has sufficient strength for use in fuel lines. It has been shown to have nearly the PSI of steel brake lines, and its flexibility means it can withstand constant flex in one spot better than steel. This makes it ideal for use in fuel lines, where its softness will not compromise its functionality.

NiCopp is corrosion-resistant
NiCopp is a nickel-copper alloy, commonly referred to as '90-10 copper', with 70% copper and 30% nickel. It is a highly corrosion-resistant material, which is also used for its strength and formability. NiCopp is often used in vehicle brake, fuel, and transmission systems, as well as hydraulic/fluid transfer systems, where steel lines are commonly used. It is particularly useful in harsh environments, where corrosion is a concern, and it is DOT approved for hydraulic brake systems.
NiCopp is a super-premium brand in brake lines and is widely used in Europe, in vehicles such as Volvo, Audi, Porsche, and Aston Martin. It is a popular choice for its corrosion resistance and ease of use, bending 58% more easily than steel tubing. It is also available in a range of coil lengths, including 25', 50', and 100'.
NiCopp is a good choice for fuel lines as it is strong, corrosion-proof, and easy to bend and flare without kinking. It is also a permanent fix, unlike steel, which can rust and corrode over time. NiCopp is particularly useful for fuel lines that require constant flexing, as its flexibility reduces the chance of cracking.
While NiCopp is a good choice for fuel lines, it is a softer material, which can cause issues with compression fittings. It is important to get the correct size compression fittings to avoid leaks, and some users have found that ferrules cannot "bite" on the line, causing issues with the compression nuts. However, this can be overcome with the use of inserts or flares.

NiCopp is harder to work with than steel
NiCopp is a nickel-copper alloy brake tubing that meets SAE Standard J1047 and ISO 4038. It is composed of approximately 9.2% nickel, 1.4% iron, 0.8% manganese, and 88.6% copper. It is also known as '90-10 copper' and has been used in several European vehicle brake systems since the 1970s. NiCopp is often used as an alternative to steel tubing in hydraulic/fluid transfer systems on vehicles, including brake, fuel, and transmission systems.
While NiCopp offers several advantages over steel, it also presents some challenges in terms of workability. Here are some reasons why NiCopp can be harder to work with than steel:
- Softness: The softness of NiCopp can make it difficult to achieve a perfect flare. When flaring NiCopp lines, some users have reported issues with getting a 100% perfect flare due to the softness of the material. This can be a challenge, especially if you are seeking a precise and aesthetic finish.
- Compression Fittings: When using compression fittings with NiCopp, the softness of the material can lead to leakage issues. The ferrules in the unions may not be able to "bite" onto the line securely, resulting in leaks even when tightened properly. This challenge is unique to NiCopp and not typically encountered with steel tubing.
- Flexibility: NiCopp's flexibility, while advantageous in certain applications, can also make it more challenging to work with, especially when compared to the rigidity of steel. This increased flexibility may require additional considerations and techniques during installation and manipulation.
- Cost: NiCopp is generally more expensive than regular steel tubing. This higher cost may impact your overall project budget and could be a factor when deciding between NiCopp and steel.
Despite these challenges, NiCopp offers benefits such as corrosion resistance, ease of bending, and flexibility that make it a preferred choice in certain applications. However, it is essential to acknowledge that NiCopp does present some unique challenges that may make it harder to work with than steel in specific situations.
