Clutch Pipe Alfa Romeo Spyder 1975 ACP026

The Professional Choice for Brake and Fuel Lines

When you're replacing corroded lines under a vehicle, you want a material that is going to last the lifetime of the car. While standard copper pipe is cheap and easy to bend, it lacks the structural integrity and fatigue resistance required for high-pressure, high-vibration environments. That’s where Copper Nickel (commonly known as Kunifer, CuNi, or NiCopp) comes in.

This copper-nickel alloy is the industry standard for professional brake and fuel line fabrication. It offers the perfect balance between workability and durability, ensuring you can flare and bend the pipe without risking premature failure or stress-cracking down the line.

Why Choose Copper Nickel Over Standard Copper?

• Superior Corrosion Resistance: UK roads are brutal on under-body components. Kunifer highly resists road salt, moisture, and chemical exposure, preventing the pitting and rusting that plagues OEM steel lines.
• High Fatigue Strength: Unlike standard copper, which can work-harden and become brittle under constant engine and road vibration, copper-nickel retains its structural integrity, preventing stress-cracking over time.
• Reliable Flaring and Bending: While tougher than pure copper, it remains pliable enough to be bent by hand or with a pipe bender without kinking. It forms a perfect, leak-free DIN (bubble) or SAE (double) flare every time using standard workshop flaring tools.
• High Pressure Rating: Engineered to easily handle the extreme hydraulic pressures of modern braking systems.

Workshop Advice

If you're preparing a vehicle for an MOT or doing a complete chassis restoration, don't cut corners with cheap copper. Kunifer is slightly harder to bend than pure copper, but the payoff is a line that won't degrade, fatigue, or fail. Always use a dedicated pipe bender for tight radiuses to avoid restriction, and ensure your flaring tool is rated for copper-nickel to get clean, professional flares.

Please note: The actual pipe supplied may differ slightly in appearance from the image shown, but the material specification remains identical.

Copper pipes are more traditional and easier to work with however Copper Nickel (aka CuNI, Kunifer, cupro-nickel or NiCopp) is more resistant to corrosion and has a higher fatigue strength.
