Is the EN 857 PROKOMP 2SC compact hydraulic hose suitable for continuous use at +100Â°C and temporarily at +120Â°C without reduced lifespan?

EN 857 PROKOMP 2SC compact hydraulic hose is specified for continuous operation up to +100Â°C and temporarily up to +120Â°C. The listed operating temperature range (-40Â°C to +100Â°C, temporarily +120Â°C) means the hose is designed to withstand short-term exposures to +120Â°C without immediate failure. However, continuous use at the upper limit (+100Â°C) is the intended maximum for normal service; sustained higher temperatures accelerate ageing of the rubber compounds and can reduce long-term service life and impulse-cycle durability. The confirmed lifespan of 400,000 impulse cycles applies under the manufacturerâs specified conditions (including temperature limits). For media such as water and air, the maximum operating temperature is lower (+70Â°C), and special precautions (micro-perforation of the outer layer for air above 17 bar) are required. Conclusion: continuous use at +100Â°C is within the hoseâs rated operating conditions; occasional short-term exposure to +120Â°C is allowed per specification, but regular or prolonged exposure above +100Â°C may shorten service life and is not recommended.

Can EN 857 PROKOMP 2SC compact hydraulic hose be used with air above 17 bar without micro-perforation of the outer layer?

No. EN 857 PROKOMP 2SC compact hydraulic hose must not be used with air above 17 bar without micro-perforation of the outer layer. For air above 17 bar the specification requires micro-perforation of the outer layer to prevent damage; therefore use only a hose prepared accordingly.

Does the EN 857 PROKOMP 2SC compact hydraulic hose require specific fittings for use at 400 bar?

EN 857 PROKOMP 2SC compact hydraulic hose does not inherently require a special or proprietary fitting type solely because it is rated to 400 bar; however, fittings must be compatible with the hoseâs specifications and pressure rating. Use fittings that: - are rated for the maximum working pressure of the specific hose diameter (up to 400 bar), matching or exceeding that rating; - are designed for double steel-braid (2SC) constructions and for the hose internal diameter to ensure proper crimping or swaging and mechanical retention; - are suitable for the hose materials (oil-resistant synthetic rubber inner/outer layers) and the intended fluid (hydraulic oil, water, air) and temperature range (-40Â°C to +100Â°C, temporarily +120Â°C; for water/air max +70Â°C); - follow applicable standards and manufacturer recommendations for assembly (correct ferrules, insertion depth, crimp profiles, and torque where relevant). Additional operational notes: for air service above 17 bar, the hose requires micro-perforation of the outer layerâensure fittings and assembly method do not impede or contradict this requirement. Always follow the hose manufacturerâs assembly instructions or use manufacturer-approved fittings to maintain the confirmed impulse life (400,000 cycles) and safety at high pressures.
