What is the maximum operating pressure of the EN 856 4SP S High-Pressure Hydraulic Hose by diameter?

The EN 856 4SP S High-Pressure Hydraulic Hose has a maximum operating (working) pressure that depends on diameter, ranging from 280 bar up to 450 bar. Smaller diameters achieve the higher end of the range (up to 450 bar), while larger diameters fall toward the lower end (around 280 bar). Exact pressure per specific diameter should be confirmed from the manufacturer’s table or datasheet for precise values.

How does the EN 856 4SP S High-Pressure Hydraulic Hose perform in extremely low and high temperature environments, including short-term temperature spikes?

The EN 856 4SP S High-Pressure Hydraulic Hose is engineered for reliable operation across a wide thermal range. Its specified continuous operating window of -40°C to +100°C means it remains flexible and maintains material integrity in very low temperatures (down to -40°C) and in typical high-temperature service up to +100°C. Short-term temperature spikes up to +125°C are also tolerated, so transient overheats or brief exposure to elevated temperatures will not immediately compromise performance. Practical implications: - Low temperatures (down to -40°C): inner synthetic rubber stays oil-resistant and flexible enough to preserve flow and avoid cracking or embrittlement under normal service conditions. - High temperatures (up to +100°C continuous): hose retains pressure capability and resistance to hydraulic fluids, with outer cover protecting against accelerated weathering or abrasion. - Short-term spikes to +125°C: acceptable for brief events without immediate failure; however repeated or prolonged exposure above +100°C can accelerate ageing of rubber compounds and may reduce service life and safety margins. For critical applications with frequent extreme spikes or sustained operation above +100°C, consider additional thermal protection or a hose rated for higher continuous temperatures.
