Professional-Grade Copper Nickel (Kunifer) Brake Pipe

When you're replacing corroded brake lines to get a vehicle through its MOT, you need a material you can rely on long after the car leaves your ramp. While standard copper pipe is cheap and easy to bend, professional workshops choose Copper Nickel (commonly known as Kunifer, CuNi, or NiCopp) for jobs that require maximum durability and safety.

Copper Nickel offers the best of both worlds: it is far more resistant to the harsh road salt and moisture common on UK roads than standard steel lines, and it possesses a much higher fatigue strength than pure copper. Pure copper can work-harden and crack under the constant vibration of a vehicle's chassis. Kunifer resists this fatigue, making it the safer, more reliable choice for high-pressure braking systems.

In the Workshop:

Working with Kunifer is straightforward, though it is slightly stiffer than pure copper. It holds its shape exceptionally well once bent, allowing you to replicate neat, factory-style routing along the chassis. It flares cleanly without splitting when using a decent quality flaring tool, ensuring a reliable, leak-free seal at the unions every time.

• Superior Corrosion Resistance: Highly resistant to road salt, grime, and moisture, preventing the rust issues common with OEM steel lines.
• High Fatigue Strength: Resists work-hardening and vibration-cracking far better than standard copper.
• Easy to Form: Stiff enough to hold its shape neatly along the chassis, yet pliable enough to bend and flare with standard workshop tools.
• Professional Finish: Gives a clean, high-quality look that easily passes MOT inspection and outlasts the vehicle.
