Frequently Asked Questions
SAE J30R9 is a technical standard for fuel hoses used in high-pressure applications, such as fuel injection systems. It ensures the hose can handle higher pressures and provides better durability than standard fuel lines.
Yes, our hoses are specifically designed for high compatibility with Gasoline, Diesel, Bio-diesel, E-85, and Ethanol-extended gasoline without degrading.
CARB and EPA certifications ensure low permeation, meaning the hose prevents fuel vapors from escaping through the cover, reducing emissions and improving environmental safety.
Depending on the size, the burst pressure can reach up to 8.27 Mpa (1200 Psi), providing a significant safety margin over the standard working pressure.
Yes, the KEMO range is engineered for excellent bending properties at low temperatures, ensuring they remain flexible and crack-resistant in cold climates.
They are ideal for fuel injection systems, high-pressure fuel delivery lines in medium and heavy-duty vehicles, and any application requiring strict permeation control.
