Standard hoses can fatigue and fail under this constant assault, leading to catastrophic downtime and safety risks. We believe your equipment should be limited by your ambition, not by the durability of its components. That was the driving force behind our High Pressure 4SP Hose. Imagine a hose that doesn't just contain pressure, but conquers it. You can feel its immense strength in its firm, dense construction—a testament to the four layers of spiraled steel wire within. It has a presence that commands respect. When the system is under load, you don't hear the straining groans of a component at its limit; you hear the steady, contained hum of a system operating with absolute confidence. This hose doesn't just carry hydraulic fluid; it provides the unyielding backbone for your most powerful machines. It transforms the violent energy of high-pressure hydraulics into smooth, controlled force, allowing your equipment to perform at its peak, shift after shift, in the most challenging environments on earth.
Extreme High-Pressure Capability: The core strength of this hose lies in its four-layer steel wire spiral reinforcement. This robust construction allows it to handle extremely high working pressures , making it suitable for the most powerful hydraulic systems found in modern heavy machinery.
Superior Impulse Resistance: This hose is specifically engineered to withstand the severe pressure spikes and cyclic impulses inherent in high-performance hydraulic systems. Its spiral reinforcement provides exceptional fatigue resistance, ensuring a long and reliable service life even under the most demanding operating conditions.
Compact & Flexible Design: Despite its immense strength, the 4SP construction offers a more favorable bend radius and a more compact outside diameter compared to many other high-pressure hoses. This allows for easier routing in tight spaces and reduces the overall weight and bulk of the hydraulic system.
Exceptional Durability & Abrasion Resistance: The tough, synthetic rubber outer cover is designed to withstand the harshest operating environments. It provides excellent resistance to abrasion, cuts, ozone, and weathering, protecting the critical steel reinforcement layers from damage and ensuring maximum uptime.
The High Pressure 4SP Hose is the go-to choice for professionals who operate machinery at the absolute limits of hydraulic performance, where failure is not an option.
Heavy Construction & Earthmoving: The lifeblood of modern heavy equipment. It is the standard for high-pressure circuits in large excavators, wheel loaders, bulldozers, and backhoes, powering boom, arm, and bucket functions that require immense force and reliability.
Mining & Quarrying: Built for the extreme demands of mineral extraction. Used in massive mining trucks, excavators, and drilling rigs where hydraulic systems operate under continuous high pressure and are exposed to highly abrasive materials.
Material Handling & Port Equipment: Essential for powerful lifting and moving. Found in heavy-duty forklifts, container handlers, port cranes, and ship-to-shore gantry cranes, where the high-pressure lifting and steering circuits demand the utmost in hose performance and safety.
Agriculture & Forestry Machinery: Powering the next generation of farm and forestry equipment. Used in large combine harvesters, tractors, and forestry harvesters for functions like powerful lifting arms, cutting heads, and steering systems that operate under high load and constant pressure fluctuations.
Industrial Presses & Machine Tools: Used in high-pressure industrial applications such as metal forming presses, injection molding machines, and heavy-duty machine tools where a robust, high-pressure hose is critical for operational safety and efficiency.
The unparalleled performance of the 4SP hose is a direct result of its highly specialized, multi-layered construction, where each layer is engineered for maximum strength and durability.
Inner Tube: The fluid pathway. This tube is made from a high-quality synthetic rubber compound that is specifically formulated for compatibility with a wide range of hydraulic fluids. It provides a smooth, durable barrier that prevents leakage and protects the reinforcement from the fluid.
Reinforcement: The core of its power. This hose features four distinct layers of high-tensile steel wire, spiraled in alternating directions. This multi-spiral construction is what gives the hose its exceptional ability to withstand extreme internal pressures and absorb high-pressure impulses without failing.
Outer Cover: The protective armor. The cover is a tough, weather-resistant synthetic rubber. This layer is formulated to provide outstanding resistance to abrasion, cuts, ozone, and UV exposure. It serves as the first line of defense, protecting the vital steel reinforcement from the harsh external environment of a job site.

Q1: What is the main difference between a 4SP hose and a 2SN or R2 hose?
A1: The primary differences are pressure, construction, and impulse resistance. A 4SP hose has four layers of spiral wire and is designed for extremely high pressures and severe impulse applications. A 2SN/R2 hose has two layers of textile braid and is for general-purpose, medium-pressure applications. A 4SP hose is significantly stronger and more durable.
Q2: When should I choose a 4SP hose over a 4SH hose?
A2: Both are four-spiral hoses for very high pressure. The main difference is the cover. 4SH hoses have a more robust, oil-resistant cover, making them better suited for applications with extreme external exposure to oil and harsher abrasion. 4SP is an excellent choice for most high-pressure mobile equipment applications.
Q3: Can this hose be used with phosphate ester (HFD) hydraulic fluids?
A3: The standard 4SP hose is not compatible with phosphate ester fluids. For use with these aggressive fluids, a hose with a specially formulated inner tube, such as an EN 856 4SPH, is required. Always verify fluid compatibility with the manufacturer.
Q4: What type of fittings are recommended for this hose?
A4: This hose must be used with high-pressure hydraulic fittings specifically rated for spiral-wound hoses (like SAE 100 R15/4SP fittings). It is critical to use the correct fittings and crimp them with the proper dies and a calibrated crimping machine to ensure a safe and leak-free connection.
Q5: How important is the bend radius for this hose?
A5: It is critically important. Never bend the hose tighter than its minimum specified bend radius. Doing so can kink the hose, restrict flow, and severely damage the internal steel reinforcement, leading to premature and potentially catastrophic failure. Always use proper bends and supports during installation.
