Hard Wall Mining Hose

Built for suction and discharge applications, these robust hoses are manufactured with a heavy spring steel wire helix, designed to cater for high dynamic

Hard Wall Mining Hose is also suitable for heavy-duty industrial applications

Hard Wall Mining Hose

Preformed Hose Bends

Preformed Hose Bends are intended for use where space limitations demand a much sharper bend radius than can be achieved using a length of Hard Wall Hose

Steel wire is embedded to keep sharp and provide a suction capability

Extra rubber on outer arc can significantly increase the wearing life
