Brake pipes deliver hydraulic pressure safely, ensuring stable braking and long-term durability.
Steel, copper-nickel, and aluminum
High corrosion resistance
Precision bending & forming
Leak-proof connections
OEM & custom solutions
Our automotive brake hard lines are engineered for precise, reliable, and long-lasting delivery of hydraulic brake fluid within vehicle braking systems.
Leveraging decades of manufacturing experience, we ensure exceptional pressure resistance, corrosion protection, dimensional stability, and leak-free performance required for safety-critical brake applications.
Brake hard lines are commonly manufactured from copper-nickel alloy (CuNi), galvanized steel (Bundy tube), or stainless steel, supporting advanced braking systems including ABS / ESP.
High hydraulic pressure resistance
Ensures stable braking force transmission with minimal volumetric expansion.
Premium corrosion protection
CuNi and coated steel lines deliver long service life even in road-salt environments.
Dimensional accuracy & rigidity
CNC bending ensures precise routing and consistent brake response.
Chemical compatibility
Compatible with DOT3 / DOT4 / DOT5.1 fluids.
Reliable sealing performance
High-precision flare fittings prevent leaks under vibration and thermal cycling.
Multiple material choices
Bundy steel, stainless steel, and CuNi options available to meet performance & cost targets.
