Fuel oil transfer hoses in marine fuel systems are flexible conduits designed to safely transport fuel between tanks, vessels, and storage facilities. These hoses are built to withstand harsh marine environments, including exposure to oil, chemicals, and extreme weather conditions. They often feature reinforced layers for durability and compliance with international safety standards.

Grade: Suitable for marine fuel oil (MGO, MDO, IFO, HFO)

Viscosity Range: Up to 700 cSt at 50°C

Buoyancy: Typically non-buoyant, but buoyant variants available

Material: Nitrile rubber (NBR) inner tube, reinforced with synthetic fiber or steel wire, abrasion-resistant outer cover

Temperature Range: -20°C to +100°C (short peaks up to +120°C)

Pressure Rating: 10 to 25 bar (varies by construction)

Standards: ISO 15540 (fire resistance), ISO 7840 (static electricity), OCIMF guidelines

End Fittings: Flanges, camlocks, or quick-release couplings

Static Conductive: Yes (≤50 MΩ/m)
