The DIN 73379 Type B hose is designed for medium-pressure use and offers low-permeation performance across a wide range of fuels, including petrol, ethanol blends, sour gas, diesel, and biodiesel. With a working pressure of 10 bar and a burst pressure of 30 bar, this NBR (nitrile rubber) hose provides excellent resistance to chemicals and fuel vapours, along with superior flexibility. These qualities ensure reliable operation across demanding fuel system applications.
One of the hose’s main advantages is its heat-resistant textile braid made from CSM (chlorosulfonated polyethylene). This outer layer provides excellent protection against fuels, lubricants, and oils—even biodiesel—while withstanding temperatures from -40°C to +90°C. Its resistance to ozone and harsh weather conditions adds to its long-lasting durability, making it suitable for both indoor and outdoor use in challenging environments.
The hose complies with strict ROHS, EPA, and CARB emission regulations, including the CARB 13CCR section 2754 requirements. These standards confirm its environmental safety and low fuel vapour permeability, helping to reduce emissions and meet regulatory demands. It’s a dependable and eco-friendly option for use in modern fuel systems.
Thanks to its wide chemical compatibility, this hose can be used with fuels containing up to 50% aromatics, premium fuels, diesel, coolant fluids, and non-oxidising cleaning liquids. It’s ideal for both vehicle and industrial applications, ensuring efficient, leak-free fuel transfer. Whether installed in cooling systems or fuel lines, its durable build supports long-term, reliable use.
