Frequently Asked Questions
They are primarily used as pressure transmission lines in automotive hydraulic brake systems for cars, motorcycles, and light trucks, as well as high-pressure lines in construction and agricultural machinery.
Yes, the SAE J1401 Brake Hose is specifically designed to be compatible with both petroleum-based and water-based hydraulic fluids.
It means the hose does not expand significantly under pressure, ensuring that the force applied to the brake pedal is transmitted directly to the calipers without loss, resulting in a firmer pedal feel.
With an operating temperature range of -40℃ to +120℃ and high ozone resistance, it remains flexible in freezing cold and durable in extreme engine heat.
Both the 1/8" and 3/16" specifications are engineered to withstand a burst pressure of greater than 60MPa.
Moisture in brake fluid can lower the boiling point and cause internal corrosion; low permeation ensures the hydraulic fluid remains pure and effective.
