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

Size: 1.5" to 12" inner diameter (ID), depending on application.

Grade: Typically SAE 100R1, 100R2, or 100R14 for marine fuel transfer.

Viscosity: Compatible with fuels ranging from gasoline (low viscosity) to heavy fuel oil (high viscosity).

Buoyancy: Often reinforced with buoyant materials (e.g., foam) for floating applications.

Material: Nitrile rubber (NBR) or fluoropolymer (e.g., Viton) for chemical resistance; reinforced with synthetic fiber or steel wire.

Pressure Rating: 150 psi to 300 psi, depending on construction.

Temperature Range: -20°F to +250°F (-29°C to +121°C), varies by material.

Standards: Compliant with USCG, OCIMF, ISO 15540, and ASTM D380.

End Fittings: Flanges, camlocks, or quick-connect couplings, typically stainless steel or brass.

Static Conductivity: Electrically conductive or static-dissipative for safety.

Yes, Fuel Transfer Hoses and Marine Fuel Systems typically comply with maritime standards such as ISO 7840, ISO 15540, and USCG regulations for safety and performance.
