The issue of oxidation of brake tubes made of copper, steel and other materials is often a source of controversy among motorists. Some car owners believe that copper tubes are susceptible to oxidation, and that oxidation products can damage the brake system. Let's find out how true this is and why it is important to consider the material of the tubes when choosing them.

 

Copper: oxidizes but protects itself

The copper tubes we produce have a number of advantages due to the unique properties of the material:

  • Natural oxidation: copper is indeed prone to forming an oxide film on the surface. However, this film (patina) acts as a protective barrier, preventing further destruction of the material. Unlike rust, copper oxidation products do not flake off and do not get inside the brake system.

  • Durability: copper has high corrosion resistance, especially under normal vehicle operating conditions. The vast majority of copper tubes serve for decades.

  • Resistance to vibrations: due to the plasticity of copper, the tubes do not crack under vibrations and sudden temperature changes.


Summary: copper tubes are safe for the brake system if used correctly. They are resistant to corrosion and retain their properties throughout their service life. In fact, according to ISO 4925, copper tubing can be used in the brake system if the brake fluid is properly alkalized. However, copper can be oxidized and destroyed if the alkalinity is not correct. We therefore recommend monitoring the alkalinity of the brake fluid with a test. The ideal pH level is between 7.2 and 8.7. We also recommend using the appropriate brake fluid for the longevity of your vehicle's brake system.

 

Galvanized steel: reliable protection against rust

Galvanized steel is another popular material we use for brake tubes. The zinc coating effectively protects the tubes from corrosion:

  • Corrosion barrier: zinc prevents the steel from coming into contact with moisture and oxygen, minimizing the risk of rust.

  • Reasonable cost: These tubes are ideal for those looking for a balance between price and durability.

  • Proven technology: galvanizing is widely used in the automotive industry and has proven to be a reliable solution.

  • Polyvinyl fluoride-coated steel: maximum protection.

 

Our polyvinyl fluoride (PVF) coated steel tubes offer the highest standard of corrosion protection:

  • Durability: PVF coating not only protects against rust, but is also resistant to mechanical damage and chemicals.

  • Aesthetics and functionality: tubes with this coating have a neat appearance and guarantee stable operation even in extreme conditions.

  • The choice of professionals: this type of tubes is suitable for vehicles operating in regions with high humidity and a large number of reagents on the roads.

 

What about brake system clogging?

One popular myth is that oxidation products from copper or other materials can clog the brake system. 

The reality is:

  • Copper tubes: the oxidation products (patina) remain on the outer surface of the tube and do not penetrate.

  • Galvanized and PVF-coated tubes: these materials have additional barriers that prevent corrosion and contamination of the system.

  • Production quality: we carefully control the production process to ensure complete safety and compliance with standards.

 

Why choose our tubes?

We offer solutions to any problem:

  • Copper tubes: durability, easy installation, high resistance to vibrations.

  • Galvanized steel tubes: optimal balance of price and quality.

  • PVF-coated steel tubes: maximum protection in extreme conditions.

Each of the materials has its own advantages and our range allows you to choose the perfect solution for your needs.

 

Conclusion.

It's important to remember that myths about brake line oxidation often arise from a lack of information. Our tubes are the product of high technology and proper quality control. Regardless of the material you choose, you can be sure that they will ensure long and safe operation of your car.
