Therefore, it is crucial to select a hose that is compatible with the chemical makeup of diesel fuel and its additives.
Nitrile rubber (NBR) is a popular choice for diesel fuel lines due to its good resistance to diesel fuel and its additives. NBR hoses are widely used in fuel systems and are compatible with diesel, biodiesel, gasoline, oil, grease, and water. They offer excellent wear resistance and high-temperature resistance, with a temperature range of -40°F to 257°F. The premium NBR construction also makes it compatible with a wide range of fluids, including methanol, nitromethane, hydraulic fluid, and pump gas.
However, it is important to note that not all NBR blends are suitable for diesel fuel. Some general-purpose NBR blends may not be specifically formulated for fuel applications, so it is crucial to choose NBR hoses that are designed for diesel fuel. Industry standards, such as SAE J30R or ISO 4217, can provide assurance of compatibility. Additionally, consulting a qualified professional in hydraulics or fuel systems can help ensure that the selected hose is suitable for the specific application.
The pressure rating of the hose is another important consideration. The hose's pressure rating should meet or exceed the fuel system's pressure requirements. For example, the NBR fuel line with a 3/8 inch inside diameter has a working pressure of 300 psi and a burst pressure of 1200 psi. Therefore, it is essential to consider the work pressure of the application before purchasing a diesel fuel line.
In summary, while Nitrile rubber (NBR) is a popular option for diesel fuel lines due to its compatibility and resistance to diesel fuel, it is important to select the correct NBR blend and ensure that the hose meets industry standards and pressure requirements for safe and optimal performance.
