The EN856 4SP hydraulic hose is a robust and reliable solution designed for medium-pressure hydraulic applications where strength, durability, and consistent performance are essential. Engineered with a four-layer spiral reinforcement of high-tensile steel wire, this hose delivers outstanding structural integrity and pressure resistance, making it an ideal choice for equipment operating in demanding environments.
Unlike standard braided hoses, the EN856 4SP features a spiral wire construction that significantly enhances its ability to withstand higher pressures and frequent pressure pulses. This four-layer spiral design not only reinforces the hose against internal pressure surges but also improves impulse fatigue resistance, contributing to a longer service life under continuous medium-pressure operation.
While not classified as a high-pressure hose like SAE 100R13 or R15, the EN856 4SP is purpose-built for medium-pressure systems that still require dependable strength and performance. It is commonly used in construction machinery, agricultural equipment, mining operations, and stationary hydraulic systems where pressures typically range from 25 to 32MPa, depending on the hose size.
The hose’s inner tube is made of oil-resistant synthetic rubber, ensuring compatibility with a wide range of hydraulic fluids. Its abrasion- and weather-resistant outer cover adds another layer of protection, allowing the hose to perform reliably in outdoor or abrasive environments. Additionally, the spiral construction allows for improved flexibility compared to traditional multi-braid designs in similar pressure ranges.
EN856 4SP hoses strike a balance between strength and economy, making them a popular choice for users needing a durable, four-layer steel wire reinforced hose in medium-pressure hydraulic systems. With its rugged design, solid pressure capabilities, and proven reliability, the EN856 4SP provides excellent value in challenging industrial applications.
