Frequently Asked Questions
The SAE J30R9 standard specifies requirements for fuel hoses used in high-pressure applications, such as fuel injection systems, ensuring they can handle higher pressures than standard R7 hoses.
Yes, KEMO SAE J30R9 hoses are engineered for excellent gasoline resistance and are fully compatible with diesel, bio-diesel, E-85, and ethanol-extended gasoline.
CARB and EPA certifications ensure the hose meets low permeation standards, meaning it prevents fuel vapors from escaping through the hose wall, reducing emissions and increasing safety.
Our hoses are designed with excellent bending properties at low temperatures, preventing cracking and maintaining flexibility in freezing environments.
For sizes from 1/8'' to 1/2'', the working pressure is rated at 2.06 Mpa (300 Psi), with a burst pressure of up to 8.27 Mpa (1200 Psi).
Absolutely. The high tensile strength and vibration resistance make these hoses suitable for medium and heavy-duty applications across various automotive and industrial markets.
