The set includes two rigid copper brake lines for the rear beam (flexible line connectors)

• External rear left NR 8
• External rear right NR 9

In addition to this set, we add 500ml of DOT-4 brake fluid

Product information:

Our series of rigid copper brake lines ZPHM are made of high-quality, seamless CuDHP R200 copper tube, compliant with the PN-EN 12449 standard. This tube comes from a leading European mill, ensuring:

Strength:

• Copper brake lines can operate at working pressures up to 220 bars, and an additional safety factor of x3.5 means that the bursting pressure exceeds 750 bars. For comparison, in a typical brake system, the maximum pressure reaches around 100 bars.

Easy installation:

• Copper with hardness R200/R220 is relatively ductile, allowing for flaring and shaping even with simple hand tools, greatly facilitating installation.

Ready-to-install set:

• The lines in our set are ready for installation - they have the appropriate flare types, and the ends have the correct size and thread pitch. Each line is made to measure and marked with a location, significantly speeding up installation.
• The dimensions of the lines are precisely matched based on the vehicle manufacturer's technical specifications. Additionally, our technical department verifies the correctness of the part selection based on the VIN number, ensuring maximum accuracy and minimizing the risk of discrepancies between catalog data and the actual vehicle condition.

High-grade galvanized steel end fittings:

• The line ends in ZPHM sets are made of galvanized, high-grade automatic steel, providing high corrosion resistance. Each end fitting is a Polish product, guaranteeing controlled quality and compliance with European standards.
• Also available are versions ZPHM/M - ZPHM/I made with brass or stainless steel end fittings.

Installation and shaping:

• The lines are delivered in coils, properly protected during transport. Before installation, they require shaping. Bending tools can be used for shaping, but a skilled mechanic can also handle it without specialized tools.

Summary:

• Rigid copper brake lines are an excellent choice for those seeking products combining high corrosion resistance, durability, and ease of installation. Made of high-quality materials, ZPHM sets guarantee long-term reliability, even in challenging operating conditions. Their ease of shaping makes installation quick and trouble-free, resulting in cost savings, making them an attractive option for owners of older or more budget-friendly vehicles.

FAQ - Frequently Asked Questions

Which to choose - copper ZPHM or steel ZPHS rigid lines?

1. What are the advantages of rigid copper brake lines:

Copper lines are corrosion-resistant, making them ideal for environments with a high degree of corrosion. Additional advantages of copper lines include:

• Easy flaring and bending - Copper is easy to work with, so flaring and bending are easier and can be done with basic tools.
• Faster installation and shaping - Copper's ductility allows the lines to be easily shaped, reducing installation time and making replacement less complicated.
• Economical choice - Copper lines are a cheaper alternative to steel lines, allowing for cost-effective restoration of older vehicles to full functionality.

2. What are the disadvantages of copper lines?

• Copper tubing is less mechanically durable than steel tubing, but its strength parameters significantly exceed the loads typical for brake systems (the minimum bursting pressure is 7 times higher than that in the brake system)
• Copper can also react electrochemically with steel fittings or aluminum components, which over time can make disassembly difficult. For this reason, copper lines are mainly intended for "single use," there is a high probability of damaging the line during disassembly - and after each disassembly of the rigid line, it is recommended to make new flares. (to eliminate this problem, our fittings made of brass or stainless steel can be used)

3. What do steel lines exceed copper lines in?

Sets of rigid steel brake lines are characterized by higher mechanical strength and are used by most manufacturers for so-called first assembly. These lines are made of double-walled steel tubes, copper-coated inside, galvanized and painted on the outside. At PHU DONOCIK, for increased corrosion resistance, we use additional protective heat-shrinkable sleeves. Steel lines are a premium product for demanding customers who want to maintain the factory quality of the vehicle for long-term use. Steel brake lines can also be made with brass or stainless steel fittings.

4. What are the disadvantages of steel lines?

• Steel lines require more processing - flaring and bending require the use of specialized tools and higher skills.
• Shaping and installation are more difficult than with copper, so replacement is recommended for experienced mechanics. The higher installation time means higher replacement costs.
• Steel lines also have less corrosion resistance than copper lines, requiring additional periodic inspections.

5. Summary:

Both types of lines provide years of safe and reliable brake system operation. The choice of material depends on the user's preferences: copper lines are an economical, easy-to-install solution ideal for older vehicles, while steel lines are an option for customers who value durability and factory quality for years to come.
