Professional Grade Kunifer (Copper-Nickel) Brake Pipe

Any mechanic who has spent winters fighting rusted-out steel brake lines knows the value of a high-quality replacement pipe. While standard copper is easy to work with, it lacks the structural integrity required for modern high-pressure braking systems and can be prone to work-hardening. That is where Copper-Nickel (commonly known as Kunifer, CuNi, or NiCopp) comes in. It is the industry standard for reliable, long-lasting brake line fabrication.

This copper-nickel alloy offers the best of both worlds. It provides the superior corrosion resistance needed to survive harsh UK road salt, combined with a much higher fatigue strength than pure copper. This means it easily handles the high-pressure pulses of modern ABS systems without stretching or failing over time.

In the workshop, Kunifer is a dream to work with. It is pliable enough to bend cleanly by hand or with a pipe-bending tool without kinking, yet tough enough to hold its shape once routed. When it comes to flaring, it forms perfectly under a standard flaring tool, creating a clean, positive seal on both single and double flares without the splitting or cracking common with cheaper steel lines.

Why Choose Kunifer for Brake Line Repairs?

• Superior Corrosion Resistance: Unlike steel, it won't rust out, making it a permanent fix that won't have the vehicle back in the workshop next year with the same issue.
• High Fatigue Strength: Engineered to withstand high hydraulic pressures and continuous chassis vibration without work-hardening or cracking.
• Easy to Work With: Bends smoothly and flares cleanly, saving valuable time on the ramp compared to stiff, unyielding steel piping.
• MOT Compliant: A professional-grade material that MOT testers prefer to see on a vehicle, ensuring a hassle-free pass.
