Marine Hose

What is a Marine Hose?

A marine hose is a flexible, high-performance hose engineered for use in marine and offshore applications. It is typically constructed from reinforced rubber or thermoplastic materials designed to resist saltwater, fuel, oil, and extreme temperature changes.

Whether you're handling fuel delivery, engine cooling, bilge drainage, or air exhaust, the right marine hose is essential to ensure safety and optimal performance on the water.

Types of Marine Hose

We offer a wide variety of hoses to suit different marine systems and compliance requirements. Here are the most common types:

  • Marine Exhaust Hose

Marine exhaust hoses are designed to carry hot gases and cooling water away from inboard engines. These hoses must be heat-resistant, flexible, and reinforced to handle both back pressure and high temperatures. They are essential for engine safety and are often routed through confined engine bays.

  • Outboard Fuel Hose

An outboard fuel hose connects a portable fuel tank to an outboard engine. These hoses are fuel-resistant and often include primer bulbs for manual priming. They're used in both petrol-powered boats and inflatable vessels and must comply with marine fuel handling standards.

  • Outboard Fuel Line

The outboard fuel line is a complete hose assembly including connectors, fittings, and sometimes anti-siphon valves. It ensures a safe and consistent flow of fuel to the outboard engine and is critical for both safety and performance.

  • Inlet Hose

An inlet hose is used for the intake of fresh water, coolant, or even waste systems on board. These hoses need to be abrasion-resistant, flexible, and able to withstand varying pressures and temperatures -depending on the application.

Industries that use Marine Hoses

Marine hoses are suitable for a wide range of onboard systems, including:

  • Fuel Systems – Fuel hoses and lines for outboard motors and fuel tanks
  • Cooling Systems – Inlet hoses for raw water or coolant circulation
  • Exhaust Systems – Heat-resistant exhaust hoses for inboard engines
  • Ventilation – Flexible ducting hoses for air movement in engine compartments
  • Bilge & Waste Systems – Drainage hoses for bilge pumps and marine sanitation devices

Each hose in our collection is built to perform reliably in marine environments and is designed to resist degradation from UV rays, saltwater exposure, and harsh chemicals.

Key Features to Look for in Marine Hoses

When selecting the right marine hose for your vessel, consider the following:

  • Compliance: Choose a hose that meets marine safety standards (ISO 7840), like Fuelmaster
    Marine Fuel Delivery Hose    .
  • Flexibility: Essential for tight engine compartments or curved routing.
  • Material: Look for hoses made from EPDM rubber or fuel-resistant thermoplastics, like Nautilus
    Marine Exhaust Hose.
  • Pressure & Heat Resistance: Especially important for marine exhaust hoses or fuel systems.
  • Reinforcement: Braided or spiral reinforcement for added durability and crush resistance.
