Q2: What are the standard sizes and how are they measured?

Common IDs are 3.2 mm (1/8") and 4.8 mm (3/16"). Outer diameters, fitting types, and custom lengths (from 200 mm to 2.5 m) are available per project.

Q3: Which standards/testing do hoses conform to?

SAE J1401, FMVSS 106, DOT, and for global exports often ISO 3996/3997. Factory tests include burst, proof/working, permeability, whip resistance, brake fluid compatibility, ozone, and lifecycle.

Q4: Can SAE J1401 brake hose be used with all brake fluids?

Suitable for DOT3, DOT4, DOT5.1 glycol-based, mineral, and select silicone fluids. Always confirm fluid compatibility when ordering.

Q5: What is the correct installation standard?

Hoses should follow manufacturer's bend radius, no sharp twists, secured away from heat sources, compliant with SAE J1401 and FMVSS routing guides.
