The DIN 73379 Type B hose is designed for medium-pressure fuel applications and delivers low-permeation performance across a broad range of fuels, including petrol, ethanol blends, sour gas, diesel, and biodiesel. Built from high-quality NBR (nitrile rubber), it offers superior flexibility and excellent resistance to chemicals and fuel vapours. With a working pressure of 10 bar and a burst pressure up to 30 bar, this hose ensures dependable operation under demanding conditions, making it suitable for use in fuel injection systems.
One of the standout features of this hose is its heat-resistant outer layer, made from durable textile braid reinforced with CSM (chlorosulfonated polyethylene). This jacket provides resistance to fuels, oils, and lubricants — including biodiesel — while withstanding temperatures from -40°C to +90°C. Its excellent ozone and weather resistance makes it a reliable choice for use in both indoor and outdoor environments.
The hose meets strict industry standards, including ROHS, EPA, and CARB emissions compliance (13CCR section 2754), helping to minimise fuel vapour emissions and support environmental sustainability. Its low-permeation construction helps reduce atmospheric pollution, making it a smart and eco-conscious option for modern fuel systems.
With compatibility for fuels containing up to 50% aromatic content, diesel blends, coolants, and non-oxidising detergents, this hose is ideal for use in automotive and industrial applications. Its durable construction ensures safe and efficient fuel transfer, whether used in engine systems or cooling circuits, helping to maintain overall system integrity and performance.
