Abstract

Overview

Key topics and technical requirements

Scope and materials: Applies to double-walled rolled metallic tubes and compatible coated tubes for use in vehicle hydraulic brakes.
Dimensional specifications: Detailed dimensions for bare pipe diameters, wall thicknesses, single flares and flange geometries are given in tables and figures to ensure mating compatibility.
Tapped holes (cone sealing): Defines tapped-hole geometries and optional hole entry forms for reliable cone-type sealing of fittings.
Male fittings and hose end fittings: Drawings and dimension tables for male fittings and both male/female hose end fittings; throat, hex sizes and sealing faces are specified.
Mechanical and surface requirements: The standard lists mechanical characteristics for steel tubes (tensile strength, yield point, elongation, hardness) and requires inner/outer surfaces free from oxidation. The outer surface must be corrosion-protected and withstand the NSS salt spray test in accordance with ISO 9227 for at least 96 h.
Assembly torques: Minimum tightening torques are specified (for example, 30 N·m for certain M10/M12 fittings, 35 N·m for larger fittings and hose end fittings) to ensure secure connections.
Compatibility: Pipes with additional plastic coating are permitted provided they remain compatible with the specified fittings, tapped holes and flares.

Applications and who uses this standard

ISO 4038 is used by:

Automotive OEMs and tier-1 brake system suppliers for part design and specification.
Manufacturers of brake pipes, fittings and hose assemblies to ensure interchangeability and safety.
Component and materials engineers for selection of tubing and surface treatments.
Quality, testing and certification labs for acceptance testing (dimensional, mechanical, corrosion).
Maintenance, repair and aftermarket producers to match replacement parts to original specifications.

Practical applications include design/manufacture of brake lines, production control, supplier specifications, and ensuring reliable cone-sealed connections in hydraulic brake circuits.
