DIN EN856 4SH Hydraulic Hose is designed for very high-pressure hydraulic systems that require a stable hose structure, strong impulse resistance, and dependable service life under severe operating conditions. This hose uses a four-spiral steel wire reinforcement design combined with an oil-resistant synthetic rubber tube and a durable outer cover to support demanding hydraulic fluid transfer in construction machinery, mining equipment, industrial hydraulic systems, and other heavy-duty applications. It is especially suitable for installations where pressure retention, abrasion resistance, and mechanical durability are critical to hose performance and replacement intervals.

Reinforced with four layers of high-tensile spiral steel wire
Built for petroleum-based hydraulic fluids
Resistant to abrasion, weather, ozone, oil, cut damage, and aging
Suitable for demanding hydraulic systems exposed to vibration, outdoor service, and repeated pressure cycles
Compatible with multiple common industrial fitting standards

DIN EN856 4SH Hydraulic Hose is a four-spiral wire reinforced hose developed for hydraulic circuits exposed to high pressure, pulse loading, and mechanically demanding service conditions. Compared with lighter-duty constructions, the 4SH structure is intended for systems where reinforcement strength, hose stability, and outer cover durability all have direct impact on service reliability. The hose combines an oil-resistant synthetic rubber tube for hydraulic media conveyance, four spiral steel wire layers for pressure-bearing performance, and a durable synthetic rubber cover to protect the hose in abrasive and weather-exposed environments.
This hose is suitable for hydraulic systems used in construction, mining, transport equipment, industrial machinery, and similar applications where pressure fluctuations and harsh site conditions are common. From a selection standpoint, the value of a 4SH hose is not only in nominal pressure class, but also in how the construction supports dimensional stability, fitting assembly, and durability over time. For users managing replacement schedules, equipment uptime, or hydraulic assembly standardization, this hose provides a more application-oriented option than general lower-pressure hose types.
