EN856 4SP Hydraulic Hose

Q: What does EN 856 4SP mean?

It refers to a European standard hydraulic hose with four-spiral wire reinforcement , designed for high-pressure and high-impulse hydraulic applications.

Q: What is the pressure rating of EN 856 4SP hose?

Depending on size, it can handle up to 445 bar (6450 psi) of working pressure.

Q: Is EN 856 4SP suitable for marine or offshore applications?

Yes, the outer cover is resistant to saltwater, ozone, and weather conditions , making it suitable for offshore use.

Q: What is the difference between EN 856 4SP and 4SH?

Both are spiral-reinforced hoses, but 4SH hoses have a higher pressure rating and thicker reinforcement than 4SP.

Q: Can EN 856 4SP replace SAE 100R12 hoses?

In many cases, yes. Both are spiral wire hoses with similar pressure ranges, but always confirm compatibility with system requirements.

The EN 856 4SP hydraulic hose is a four-spiral steel wire reinforced, high-pressure hydraulic hose designed for use in heavy-duty hydraulic systems. Known for its superior pressure resistance, long service life, and excellent flexibility, it is ideal for applications requiring high impulse performance and extreme durability. This hose is widely used in construction machinery, mining, agricultural equipment, and industrial hydraulic systems, where reliability and resistance to harsh working conditions are critical.
