The high pressure flexible hoses with STECKO fittings are applied in powering and drain installations of hydraulic machines and devices working under pressure in difficult use conditions of the mining plants, also in rooms with fire and explosion hazard, with application of all hydraulic liquids approved for use in underground mines.

The flexible hoses are commonly used in the hydraulic systems of the mining cover combining servo-motors (supports, shifts, stands, etc.) with elements of systems: supporting (control return valves) and control (manually controlled dividers, hydraulic and electrohydraulic ones).
