dojobkinb 1/2-inch ID Fuel Line Hose 20ft – NBR Rubber, 300 PSI for Automotive Fuel Systems

Meet the dojobkinb 1/2-inch ID Fuel Line Hose, a purpose-built NBR rubber hose designed to support automotive fuel paths with confidence. It runs 20 feet long, giving you flexible routing options for tight engine bays or longer runs between components. With an inner diameter of 1/2 inch (12 mm) and an outer diameter of about 0.78 inch (20 mm), this hose is sized for steady fuel flow while staying easy to route around hoses, clamps, and brackets. The material balances resilience and flexibility, offering a practical balance for everyday use. The hose is rated for a working temperature range from -40°F to 257°F, making it capable of handling cold starts and hot engine compartments. A working pressure of 300 PSI and a burst pressure around 1160 PSI provide a comfortable safety margin for typical automotive applications. The combination of material and construction is aimed at longer service life in environments that experience vibration, heat, and exposure to fuels.

Beyond pure fuel transfer, the hose is designed for versatility. It can work with diesel, biodiesel, gasoline, oil, grease, water, and air, enabling you to use a single hose across multiple lines where fluids or air are involved. This broad compatibility helps simplify inventories in shops or DIY setups. However, because pressure and temperature vary by application, please verify your specific use case aligns with the hose rating before installation to avoid unexpected stress on the hose.
