We don’t just sell hoses; we provide certified fluid conveyance solutions tested for 200,000+ impulse cycles.
We manufacture a full range of hydraulic hoses to meet every industrial need. Our extensive product line includes SAE and DIN EN series hoses, spiral hoses, and more. With over 20 years of expertise, we guarantee durability, reliability, and peak performance for your equipment.
Our marine steering hose is engineered with a corrosion-resistant thermoplastic construction. It is designed for fast and accurate response in hydraulic steering systems, ensuring precise control. This hose is built to withstand both saltwater and freshwater environments, providing reliability and safety at sea.
We offer a marine high-pressure hose reinforced with multiple layers of high-tensile steel wire. This hose is perfect for demanding applications like deck cranes and winches, where it must handle extreme pressure surges and dynamic loads with superior strength and durability.
We offer marine suction and return hose for low-pressure applications. This type of hose is constructed to be flexible and kink-resistant, making it ideal for the smooth transfer of hydraulic fluid back to the reservoir, a vital part of a ship’s hydraulic circulation system.
Superior Saltwater & UV Resistance (MSHA Approved) Our proprietary synthetic rubber cover is engineered to surpass standard requirements. It has passed 72-hour salt spray testing without cracking or degradation. Designed to withstand continuous UV exposure and ambient temperatures ranging from -40°C to +100°C, our hoses deliver a service life 30% longer than standard SAE hoses in high-salinity maritime zones.
Engineered for 6,000+ PSI: High-Tensile Spiral Wire Reinforcement Our marine hoses are reinforced with 4 to 6 layers of high-tensile spiral steel wire, capable of withstanding working pressures up to 420 Bar (6,090 PSI) with a 4:1 safety factor. This robust structure ensures zero burst failure even under extreme hydraulic surges commonly found in deck cranes and winches.
Our fire-resistant and anti-static (FRAS) hoses reduce ignition risks, providing a crucial safety feature for onboard systems and fluid transfer.
Engineered to endure constant motion and vibration, our hoses maintain integrity without kinking, offering both flexibility and robust long-term durability.
Hoses are designed to prevent leaks and spills of hydraulic fluid, protecting marine ecosystems from contamination and helping you comply with environmental regulations.
We ensure our marine hoses meet stringent international maritime standards, guaranteeing quality and providing peace of mind for critical applications at sea.
Marine hydraulic hoses are the lifelines of vessels, playing a critical role in a wide range of onboard systems. Their ability to withstand the extreme pressures of hydraulic fluid while resisting the corrosive effects of saltwater and constant motion is essential for safety and operational efficiency. These specialized hoses are found in systems from steering to cargo handling, ensuring smooth and reliable performance in the challenging marine environment.
Steering Systems
Hoses are used to transfer hydraulic fluid to and from the rudder’s actuators, enabling the precise and powerful control needed for a ship’s navigation. These systems are crucial for safety and maneuverability, relying on the hoses’ ability to handle pressure and resist corrosion.
Deck Cranes and Winches
These hoses supply the power to operate deck machinery for lifting cargo, anchors, and other heavy equipment. They are built to withstand intense pressures and dynamic loads, ensuring the reliable and safe handling of materials on a ship’s deck.
Mooring and Anchoring Systems
Hydraulic hoses are critical for the fluid power that drives anchor windlasses and mooring winches. Their durability and strength are essential for ensuring a vessel can be securely docked and anchored, even in challenging weather and sea conditions.
Propulsion and Thrusters
In some marine vessels, hydraulic hoses are used to power bow and stern thrusters. These systems provide enhanced maneuverability, particularly in tight spaces like harbors, making a vessel easier to control and dock without the need for tugboats.
Cargo Handling
Hoses are used to operate specialized hydraulic equipment for loading and unloading cargo, particularly in tankers and other vessels with fluid transfer needs. They must be compatible with the fluids being transferred and built to rigorous safety and environmental standards.
A marine hydraulic hose is a specialized type of hydraulic hose specifically engineered to operate in the harsh and corrosive environment of the marine industry. Unlike standard hydraulic hoses, which are designed for general industrial use, marine hoses are built with a focus on resistance to saltwater, UV rays, ozone, and constant vibration.
Marine hydraulic hoses are specifically designed to operate in the harsh marine environment. Their primary difference lies in the material composition of the outer cover, which is formulated to be highly resistant to corrosion from saltwater, UV radiation, and ozone. Standard hoses lack this specialized protection and would quickly degrade in a maritime setting.
Marine hydraulic hoses are crucial for a wide range of onboard systems. Their applications include powering steering systems for navigation, operating deck cranes and winches for cargo and anchor handling, and activating propulsion and thruster systems. They are also used for fluid transfer and in power tilt/trim systems for outboard motors.
Safety is paramount in marine applications, and these hoses are built with that in mind. They feature robust, high-pressure reinforcement to prevent catastrophic failures. Many also have a fire-resistant and anti-static (FRAS) outer cover to reduce the risk of ignition in case of a leak. Their resistance to environmental degradation also ensures long-term reliability.
The lifespan of a marine hydraulic hose can vary depending on its application, usage frequency, and environmental exposure. However, with proper installation and regular maintenance, a quality marine hose can last for several years. It’s crucial to inspect hoses regularly for signs of wear, abrasion, or cracking and replace them promptly to avoid failure.
Choosing a certified marine hydraulic hose guarantees that the product meets stringent international maritime standards. These certifications ensure the hose has been rigorously tested for pressure, material compatibility, and durability in a marine environment. Using a non-certified hose can compromise the safety and reliability of critical onboard systems.
