The DIN 73379 Type B fuel hose is designed as a medium-pressure, low-permeation option suitable for a range of fuels, including gasoline, ethanol, sour gas, diesel, and biodiesel. It offers a working pressure of 10 bar and can withstand bursting pressures up to 30 bar, ensuring reliable performance under tough conditions. Made from NBR (nitrile butadiene rubber), the hose features excellent resistance to chemicals and permeation, combined with high flexibility. These qualities make it a dependable solution for fuel injection systems across various applications.
A notable characteristic of this hose is its heat-resistant textile braided cover, made from CSM (chlorosulfonated polyethylene). This cover provides outstanding resistance against fuels, oils, lubricants—including biodiesel—and endures temperatures ranging from -40°C to +90°C. In addition, the CSM braid offers strong protection from ozone and harsh weather, extending the hose’s lifespan and maintaining its integrity in challenging environments. This makes it well-suited for diverse operational settings where durability and environmental resistance are vital.
Complying with strict industry regulations, this fuel hose meets ROHS, EPA, and CARB emission standards, specifically fulfilling CARB requirements as outlined in 13CCR section 2754. These certifications confirm the hose’s adherence to environmental and safety guidelines, making it a responsible and environmentally conscious choice. Its low permeation design helps limit fuel vapor emissions, contributing to reduced environmental impact.
The DIN 73379 Type B hose is highly versatile, compatible with fuels containing up to 50% aromatic content, various high-quality fuels, diesel, coolant fluids, and non-oxidizing liquid detergents. This adaptability makes it ideal for automotive and industrial fuel and coolant systems, ensuring safe and efficient fluid handling. Its robust build and dependable performance help maintain optimal fuel system operation and integrity.
