Designed for hydraulic torque systems and critical applications, CEJN hoses withstand pressures up to 300 MPa with reinforced steel construction and low volumetric expansion. Available in multiple configurations, they provide safety, thermal resistance from -40°C to +100°C, and customized assembly for extreme industrial demands.
Safety hoses for ultra-high-pressure hydraulic systems
CEJN ultra-high-pressure hoses for hydraulic systems are manufactured using polymer materials reinforced with steel spiral layers, maintaining excellent flexibility. Their low volumetric expansion ensures fast response times in hydraulic systems while minimizing pressure drop. The reduced outer diameter makes these hoses ideal for torque applications. Each hose assembly is custom-built according to customer requirements and crimped with one of our wide range of end fittings, with high-pressure quick couplings also available as an optional feature.
