Clutch Pipe Austin A55 Mk1 ACP071

The Professional's Choice for Brake Line Replacements

Dealing with corroded brake lines is a standard part of life in British workshops, especially when MOT season rolls around. While standard copper pipe has historically been the go-to for quick fixes due to how easy it is to bend, Copper Nickel (Kunifer) is the industry standard for a permanent, professional-grade repair.

Why Choose Copper Nickel (CuNi) Over Standard Copper?

Standard copper is soft and easy to work, but it lacks the high tensile strength required for modern, high-pressure braking systems—especially those equipped with ABS. Over time, pure copper can also suffer from work-hardening and internal chemical degradation.

Copper Nickel (often referred to as Kunifer, CuNi, or NiCopp) is an alloy engineered to solve these exact issues:

• Superior Fatigue Strength: It easily withstands the constant high-pressure cycling of modern braking systems without stretching or fatiguing.
• Extreme Corrosion Resistance: It is highly resistant to road salt, moisture, and agricultural run-off, meaning it won't rust out like OEM steel lines or oxidise like cheap copper.
• Excellent Workability: While stiffer than pure copper, it still flares cleanly and consistently using standard workshop flaring tools (for both DIN and SAE flares) and can be bent smoothly without kinking.

In the Workshop

When routing this line along the chassis, you will find it holds its shape far better than soft copper. It snaps securely into original OEM brake line clips without sagging, giving you a neat, factory-level finish that looks right and passes inspection every time.

Whether you are plumbing a complete classic car restoration from scratch or splicing in a section to replace a rotted rear line on a daily driver, using Kunifer means you do the job once, and you do it right.

Please note: The physical appearance or coiling of the pipe supplied may vary slightly from the product image.
