Key Features

• Validated for high fatigue resistance
• Upgraded temperature resistance
• Superior abrasion resistance
• High ozone and weather resistance
• Flame resistance to a wide range of specs.
• Antistatic and antitoxic cover
• BIO biological and mineral oils compatibility

Very high pressure hydraulic hose with high fatigue, abrasion and environmental resistance. The high pressure rating has been achieved by a special design that incorporates 4 wire spirals as well as the use of Interlock Plus internal and external skive fittings. Its field of expertise are the most demanding applications in high abrasive applications like mining or construction. As expected from a mining hose, the ROCKMASTER 4SH has an upgraded peak operating temperature of 125 C, antistatic and flame resistant cover. On top of that, Manuli R&D centers have created a product that exceeds the EN 856 4SH norm requirements.
