Why Professional Builders Choose Copper Nickel (Kunifer) Pipe

Any mechanic who has spent winters fighting rusted-out steel brake lines knows the value of a quality replacement. While standard copper pipe is cheap and easy to bend, it lacks the structural strength required for high-vibration, high-pressure environments over the long haul. That is why professional workshops upgrade to Copper Nickel—commonly known as Kunifer, CuNi, or NiCopp.

This pipe offers the ultimate balance of workability and durability. It is tough enough to withstand the harshest road conditions but remains malleable enough to flare and bend without kinking, provided you are using decent workshop tools.

Key Workshop Benefits:

• Superior Corrosion Resistance: Unlike standard steel lines that rot out from road salt and moisture, Copper Nickel is highly resistant to oxidisation. This makes it the go-to choice for lasting MOT passes and classic car restorations.
• High Fatigue Strength: Brake systems operate under immense pressure, and lines are constantly subjected to engine and road vibrations. Kunifer has a significantly higher fatigue strength than pure copper, preventing the work-hardening and cracking that can lead to catastrophic pedal failure.
• Excellent Workability: While slightly stiffer than soft copper, it flares predictably and holds its shape perfectly once routed along the chassis. It works exceptionally well with both turret-type and hand-held flaring tools.

Mechanic's Tip:

When routing Kunifer, take your time with a proper pipe bender to get those factory-look radius bends. Unlike cheap copper, which can look untidy and sag over time, Kunifer stays rigid once clipped into place, keeping the underside of the vehicle looking clean and professional.

Please note: The physical appearance of the pipe coil may vary slightly from the image shown, but the metallurgical specification and performance remain identical.
