Product Information
Full details
This Connect Copper Brake Pipe is designed for automotive professionals and DIY enthusiasts needing to replace damaged or deteriorated brake lines. Its primary benefit is the pliable, easy-to-work-with C106 copper construction, allowing for simple bending and shaping to fit vehicle brake systems. A potential caveat is its soft-annealed nature, which requires careful handling during installation to avoid accidental kinking.

FAQs
What is the main advantage of using copper brake pipe?
The main advantage is its exceptional pliability, making it much easier to bend and shape compared to steel brake lines, which simplifies installation and repair work.
Can this copper pipe be used for other fluid systems?
While primarily designed for automotive brake lines, it can be used for other low-pressure hydraulic fluid control systems where copper is suitable and the pressure rating is not exceeded.
What tools are needed to install this brake pipe?
You will need a tubing cutter, a pipe bender, and a double flaring tool. Standard wrenches are also required for connections.
How does the safe working pressure compare to steel brake lines?
This copper pipe has a safe working pressure of 1900 psi. Steel brake lines typically have higher pressure ratings, but for most standard automotive applications, 1900 psi is sufficient.
Is this pipe suitable for all vehicles?
It is suitable for most vehicles requiring 5/16" brake lines, especially for repairs where ease of bending is a key factor. Always confirm the correct pipe diameter for your specific vehicle.
What does 'soft annealed' mean in relation to the copper?
Soft annealed means the copper has been heat-treated to make it as soft and pliable as possible, significantly improving its bendability and ease of flaring.
Can I reuse old brake line fittings with this pipe?
It is generally recommended to use new fittings with new brake lines to ensure a reliable seal. If reusing old fittings, ensure they are clean, undamaged, and compatible with the flare type.
Troubleshooting
Pipe kinks during bending
Use a proper pipe bender and support the pipe from the inside or outside. Make bends gradually and avoid tight radii. If a kink occurs, it may be best to cut out the damaged section and re-flare.
Difficulty flaring the pipe
Ensure you are using a quality flaring tool designed for soft metals like copper. Make sure the pipe end is clean and properly deburred before attempting to flare. Anneal the end slightly if the material is too stiff, though this is uncommon with this product.
Leaks at connection points
Re-check the flare for cracks or imperfections. Ensure the fitting is the correct size and type for the flare. Tighten the fitting securely but do not overtighten, which can damage the flare or fitting.
Pipe wall appears thin or damaged
Inspect the entire length of the pipe for any signs of damage, pitting, or thinning. The specified gauge is 22, and damage can compromise the safe working pressure. If significant damage is found, replace the section.
Pros and Cons
Pros
- Easy to bend and shape for custom fittings.
- Copper construction offers excellent corrosion resistance.
- Simplifies the flaring process for secure connections.
- Adequate length (25ft) for most brake line replacement jobs.
- Meets industry standards for safety and quality.
Cons
- Soft material can kink if not handled carefully during bending.
- May require specific flaring tools for optimal results.
- Not suitable for applications requiring extreme rigidity.
- Copper can be more susceptible to damage from impacts compared to steel.
Setup, Compatibility & Care
Setup:
- Measure and Cut: Carefully measure the required length of pipe. Use a dedicated tubing cutter to ensure a clean, square cut.
- Bend: Gently bend the pipe to the desired shape using a pipe bender to avoid kinking. Support the pipe during bending if necessary.
- Flare: Use a double flaring tool to create the appropriate flare at each end of the pipe, ensuring it matches the fitting type (e.g., SAE or ISO).
- Connect: Attach the flared ends to the corresponding brake components (e.g., brake hoses, master cylinder, wheel cylinders) using appropriate fittings and wrenches.
- Test: After installation, bleed the brake system thoroughly and check for leaks under pressure.
Compatibility:
- Fluid Control Systems: Suitable for use on all hydraulic fluid control systems, most commonly automotive brake lines.
- Fittings: Compatible with standard 5/16" brake line fittings. Ensure flares are correctly made for a secure seal.
Care:
- Storage: Store the roll in a clean, dry place to prevent contamination or damage. Keep the ends capped when not in use.
- Handling: Avoid sharp bends or twists, which can weaken the pipe or cause kinking. Use appropriate tools for bending and flaring.
- Cleaning: If the pipe becomes dirty during installation, clean it with a lint-free cloth. Avoid abrasive cleaners.
