MSHA approved, flame retardant and antistatic hoses are designed for power and run-off installations of machines and devices operating under high pressure in underground mines with methane and coal dust explosion hazard.

Hoses may be used for:
– hydraulic liquids in accordance with ISO 6743-4, except for HFD R, HFD S, HFD T (from -40°C to +100°C),
– water solutions (from -40°C to +70°C),
– water (from 0°C to +70°C),
– compressed air (from 0°C to +80°C).

These hoses are not suitable for liquids containing castor oil and esters.

Working pressures
From 63 to 225 bar depending on diameter.
