Frequently Asked Questions
It is primarily used as a pressure transmission line in hydraulic brake systems for cars, motorcycles, light trucks, and heavy-duty vehicles, as well as in industrial and agricultural machinery.
Yes, the hose is designed to be compatible with both petroleum-based and water-based hydraulic fluids.
Low expansion ensures that the force applied to the brake pedal is transmitted directly to the calipers without the hose "swelling," resulting in a firmer pedal feel and shorter stopping distances.
It is engineered to operate safely in temperatures ranging from -40℃ to +120℃, ensuring reliability in both arctic and desert environments.
Ozone resistance prevents the rubber from cracking (dry rot) over time due to atmospheric exposure, which is critical for preventing sudden brake failure.
Both the 1/8" and 3/16" inner diameter hoses are rated with a burst pressure of greater than 60 MPa.
