This premium multi-layer fuel hose, engineered in compliance with DIN 73379-3E (11/97), combines advanced materials to ensure maximum durability, safety, and performance in the most demanding conditions. Its inner layer, crafted from high-grade Viton® (FPM), guarantees outstanding resistance to hydrocarbons, petrochemical derivatives, aggressive fuel additives, and biofuels, even under elevated temperatures. The intermediate epichlorohydrin (ECO) layer, reinforced with a robust aramid fiber braid, delivers exceptional strength, thermal stability, and long-lasting reliability, while the outer ECO layer protects against ozone, micro-cracking, and extreme weather exposure. Designed for modern fuel systems, the hose is perfectly suited for biodiesel blends such as B10, B20, and B100, resistant to rapeseed methyl ester (RME), and compatible with ethanol-based fuels like E10 and E100. Its versatility extends to conventional diesel, gasoline, mineral oils, and phosphate ester additives, making it an ideal solution for industries requiring high fuel purity, resistance to aging, and minimal hydrocarbon permeability. With a working pressure of 10 bar and an operating temperature range from -40°C to +125°C, this hose ensures reliable performance, extended service life, and optimal safety across a wide spectrum of applications.
