Durable Fuel Line Hose Leak Proof Heat Resistant Flexible Design

Description

The Fuel Hose Pipe is a high-performance flexible conduit designed for the safe and efficient transfer of diesel, gasoline, and marine fuel oils under high pressure and variable temperature conditions. Constructed from premium synthetic rubber and reinforced with multi-layer textile or steel wire braiding, it provides excellent durability, chemical resistance, and thermal stability. The hose maintains consistent performance even in harsh marine environments, ensuring smooth fuel delivery from storage tanks to engines, pumps, or auxiliary systems.

Each hose is engineered and tested in accordance with ISO 1825, EN 1360, and SAE J1527 standards to guarantee reliability and compliance with international maritime safety regulations. The inner tube offers excellent resistance to aromatic hydrocarbons, while the outer cover is formulated to withstand UV exposure, saltwater, and abrasion. With customizable sizes, pressure ratings, and end fittings, the Fuel Hose Pipe meets the demanding requirements of offshore platforms, port fueling stations, and shipboard systems.

Case Study

In 2024, a major port authority in Southeast Asia partnered with Hongruntong Marine to upgrade its aging bunkering system. The existing fuel transfer lines suffered from frequent leaks and corrosion due to exposure to saline air and fluctuating pressure. Our engineering team conducted a detailed on-site assessment and proposed replacing the system with Hongruntong’s Reinforced Fuel Hose Pipe Series HRT-FP600.

The installation involved 300 meters of flexible hose integrated with quick-connect camlock fittings and stainless-steel end couplings. The new hoses were designed to operate at a maximum working pressure of 2.5 MPa and a temperature range of -40°C to +90°C, ensuring stable performance even during rapid fueling operations.

After implementation, the port reported a 35% reduction in fueling time and a complete elimination of leakage incidents within six months. Maintenance requirements dropped significantly, as the hoses resisted kinking and external abrasion from deck machinery. The success of this project led to the adoption of the same hose series by two nearby terminals, demonstrating Hongruntong’s reputation for safety, quality, and reliability in marine fuel systems.

Key Features

Multi Layer Reinforced Construction
Each hose features an inner tube of high-grade NBR or FKM rubber designed to resist aromatic hydrocarbons, ethanol blends, and biodiesel components. The middle reinforcement layer is composed of synthetic textile cords or stainless-steel wire braids to prevent bursting under high pressure. The outer layer is coated with ozone-resistant, flame-retardant rubber to enhance safety and service life in demanding port environments.

Superior Thermal and Chemical Resistance
The Fuel Hose Pipe retains flexibility and mechanical strength across a wide temperature range, typically from -40°C to +100°C. It resists degradation caused by prolonged exposure to UV light, seawater, and various chemical vapors. Even when handling high-aromatic fuels, it maintains its structural integrity and sealing performance, reducing the risk of cracking or blistering.

Leak Proof and Anti-Kink Design
Precision manufacturing and seamless bonding between layers ensure absolute leak prevention. The hose body is engineered with an optimized bending radius that prevents kinking or flattening during heavy use or repetitive motion. This design enhances fuel flow stability and reduces maintenance downtime caused by deformation.

Customizable End Connections and Lengths
Hongruntong offers a wide range of coupling options—camlock, flange, threaded, or quick-release—compatible with global fuel transfer systems. Each assembly undergoes hydrostatic testing to verify safety and performance. Lengths, diameters, and pressure ratings can be tailored to customer specifications, allowing integration into both stationary and mobile fueling systems.

Applications

Port Bunkering Systems
Ideal for refueling vessels at port terminals, ensuring fast, clean, and safe transfer of marine diesel oil or heavy fuel oil. The hose’s flexibility enables easy handling across docks and decks with limited space.

Offshore and Shipboard Fuel Supply
Used for connecting storage tanks, day tanks, and main engine systems on offshore platforms and vessels. Resistant to salt corrosion and vibration, the hose guarantees continuous, reliable operation under dynamic sea conditions.

Harbor and Shipyard Maintenance Operations
Applicable for mobile fuel dispensing units and service barges in shipyards. Its lightweight structure allows quick deployment for temporary or emergency fuel supply without performance compromise.
