The ISO7840 collection, including both A1 and A2 specifications, is engineered to meet the demanding safety and performance standards required for marine fuel systems. Designed specifically for fuel transfer in maritime environments, these hoses provide exceptional reliability for a wide range of vessels, from recreational boats to commercial marine fleets. Built to the rigorous ISO7840 standard, this collection delivers the durability, flexibility, and safety that marine professionals and boat owners trust on the water.

Our ISO7840 A1 hoses are designed for fuel feed lines where the hose will be located within an engine compartment or enclosed spaces. These A1-rated hoses feature high resistance to fire and ensure minimal fuel permeation, providing the highest level of safety in confined areas where fuel vapors could accumulate. Crafted from premium, flame-resistant materials, A1 hoses are the ideal choice for inboard engines or situations where the hose may be exposed to heat.

The ISO7840 A2 hoses, on the other hand, are intended for fuel fill and vent applications in areas outside of engine compartments. These hoses also provide outstanding resistance to fuel permeation and offer a high level of safety for marine fuel systems. While not specifically designed for exposure to high heat, A2-rated hoses are highly flexible and corrosion-resistant, ensuring easy installation and a long service life, even in tough marine environments.

Both A1 and A2 hoses in the ISO7840 collection are constructed from robust, fuel-resistant materials that prevent degradation from continuous contact with gasoline, diesel, and other petroleum-based fuels. These hoses are designed to withstand the corrosive effects of saltwater, UV exposure, and the harsh marine climate, ensuring longevity and reduced maintenance needs.

Flexibility and ease of handling are essential features in the ISO7840 collection. These hoses are engineered for straightforward routing, fitting effortlessly into the tight spaces typically found on boats and yachts. Their lightweight and flexible construction simplify installation without compromising on strength, making them a top choice for marine technicians and DIY boat owners.

Each ISO7840 hose is equipped with reinforced layers to provide added protection against leaks, ruptures, and wear. This multi-layered construction ensures that both A1 and A2 hoses deliver safe, dependable fuel transfer, even under challenging conditions. The hoses are rigorously tested to meet stringent marine safety standards, helping to prevent fuel spills and reduce the risk of fire hazards.

With the ability to perform across a broad temperature range, the ISO7840 A1 and A2 hoses are suitable for a variety of climates and marine applications, from tropical coastlines to colder northern waters. This adaptability makes them ideal for diverse marine fuel needs, supporting reliable operation wherever your vessel takes you.
