Rubber hydraulic hoses – general information
Rubber hydraulic hoses are used in high pressure hydraulic systems for control and power supply. They are designed to transfer hydraulic oil primarily (hydraulic fluid compliant with ISO 6743-4, apart from HFD R, HFD S and HFD T fire-resistant fluids). For other applications (e.g. for compressed gases) always contact Technical Department of TUBES INTERNATIONAL®. For water, water-based fluids and air, the maximum working temperature is +70°C. For air over 17 bar, the external layer of the hose should be pinpricked and have additional protection.
