Product Overview
LEAD-FLEX EN856 4SP is a high-performance spiral hydraulic hose tailored for rigorous high-pressure hydraulic systems. As a core product in the high-pressure steel wire spiral hose category, it integrates durability and reliability to meet industrial demands. The hose features a precision-engineered structure: an oil synthetic rubber inner tube forms the foundation, ensuring seamless compatibility with most hydraulic fluids and resisting internal corrosion. It is reinforced with four or six layers of high-strength spiral wire reinforcement—a key design element that enhances the hose’s ability to withstand extreme pressure without deformation. The outer layer is a tough oil and weather resistant rubber cover, which shields the hose from external factors like UV rays, moisture, and mechanical scratches, extending its service life in both indoor and outdoor settings. Whether used in heavy machinery or industrial equipment, LEAD-FLEX EN856 4SP stands out as a dependable solution for high-pressure fluid transfer.
Product Advantage
Superior Pressure Resistance: The multi-layer spiral wire reinforcement delivers exceptional structural integrity, allowing the hose to handle high operating pressures consistently. This eliminates the risk of leaks or bursts even in high-stress hydraulic circuits.
Broad Fluid Compatibility: The oil synthetic rubber inner tube works seamlessly with a range of common hydraulic fluids, including glycol, mineral oil, and emulsions. This versatility reduces the need for multiple hose types in diverse applications.
All-Weather Durability: The weather resistant rubber cover ensures the hose performs well in harsh environments—from dry industrial workshops to outdoor construction sites. It resists aging and degradation, maintaining performance over time.
Wide Temperature Adaptability: With an operating temperature range from -40℃ to +120℃, the hose functions reliably in extreme cold and heat. For water-based media, it adjusts to a safe range of 0℃ to 70℃, adding flexibility for different use cases.
Long-Term Reliability: Every component is selected for durability, minimizing maintenance needs and replacement frequency. This lowers overall operational costs for users.
Product Uses
LEAD-FLEX EN856 4SP is widely applied in scenarios where reliable high-pressure hydraulic fluid transfer is critical. Its primary uses include:
Industrial Hydraulic Systems: It is commonly used in manufacturing facilities to connect hydraulic presses, injection molding machines, and assembly line equipment. The hose’s compatibility with mineral oil and lubrication oils makes it ideal for keeping these machines running smoothly.
Heavy Machinery & Construction: In construction and mining, the hose is installed in excavators, loaders, and mining equipment. Its weather resistant cover and pressure resistance withstand the rough conditions of construction sites and opencast mining operations.
Agricultural Equipment: Farm machinery like tractors and harvesters rely on the hose to transfer hydraulic fluids for functions such as lifting and steering. The hose’s ability to handle emulsions and wide temperatures suits the varying outdoor conditions of agricultural work.
It is important to note that LEAD-FLEX EN856 4SP cannot be used for conveying phosphate ester groups. These fluids can react with the inner tube material, causing degradation, leaks, and potential equipment damage.
FAQ
What does "EN856 4SP" mean for this hydraulic hose?
EN856 4SP refers to the industry standard that the hose complies with, specifically focusing on its reinforcement structure. The "4SP" indicates that the hose uses four layers of spiral wire reinforcement (a key design feature) as its skeleton. This standard ensures the hose meets strict criteria for pressure resistance, material quality, and performance—making it a trusted choice for high-pressure hydraulic applications.
Is LEAD-FLEX EN856 4SP suitable for outdoor use?
Yes, it is highly suitable for outdoor use. The hose’s outer layer is a weather resistant rubber cover that protects it from outdoor elements like rain, UV rays, and temperature fluctuations. Additionally, its wide temperature range ensures it functions reliably in outdoor environments, whether in hot summer months or cold winter conditions. Just ensure the conveyed medium is compatible (avoid phosphate ester groups) to maintain optimal performance.
Can this hose be used with water as the conveying medium?
Yes, LEAD-FLEX EN856 4SP can convey water, but with a specific temperature limitation. When water is the medium, the recommended temperature range is within a safe interval to protect the inner tube. For other compatible media (e.g., mineral oil, glycol), the hose operates within a broader temperature range, adapting to diverse industrial needs.
