The DIN 73379 Type B fuel hose is designed as a medium-pressure, low-permeation solution suitable for various fuels such as gasoline, ethanol, sour gas, diesel, and biodiesel. It features a working pressure of 10 bar and a bursting pressure rating of 30 bar, ensuring strong performance in demanding conditions. Made from NBR (nitrile butadiene rubber), this hose offers excellent chemical resistance, low permeability, and high flexibility, making it a reliable choice for fuel injection systems across many applications.
This hose is equipped with a heat-resistant textile braided cover made from CSM (chlorosulfonated polyethylene). The cover provides exceptional resistance to fuels, oils, lubricants—including biodiesel—and maintains durability across a temperature range of -40°C to +90°C. It also offers high protection against ozone and harsh weather, extending the hose’s lifespan and making it suitable for use in tough environmental conditions.
Complying with stringent industry standards, the hose meets ROHS, EPA, and CARB emission requirements, specifically following CARB regulations referenced in 13CCR section 2754. These certifications demonstrate its compliance with environmental and safety standards, making it an eco-friendly option. Its low permeation design supports efforts to minimise fuel vapor emissions, helping reduce environmental impact.
The DIN 73379 Type B hose is compatible with fuels containing up to 50% aromatic content, various high-grade fuels, diesel, coolant fluids, and non-oxidizing liquid detergents. This versatility makes it ideal for automotive and industrial fuel and coolant applications, ensuring safe and efficient fluid transfer. Its strong construction and trustworthy performance help maintain fuel system integrity and operational efficiency.
