rigid brake line manufacturer

Introduction

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.

Key Features

• 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.
