The Slurryflex DF-Series Hard-Wall Dredge Hose is a wire-reinforced straight hose designed to be used with poly hose floats on floating pipelines. The hose diameter corresponds to the inside diameter of the hose float.

This hose consists of an abrasion-resistant rubber inner layer, and layer of wire reinforcement to create the hard wall, and an outer layer that protects it from the elements. Slurryflex Grade A rubber provides long-lasting resistance to abrasion, cutting, tearing, and overall wear.

Flexible rubber construction allows for rotation or movement on site, and minimises misalignment and vibration. The floats give the hose some flexibility of movement while also providing protection from currents, tides, and wind.

Slurryflex hoses are the most flexible, longest lasting slurry hoses on the market, as shown by independent testing. Slurryflex Grade A rubber gives you long term resistance to abrasion, cutting, and tearing.

All of our dredge hoses are custom made in Australia according to your specifications. We have the largest mining hose factory in Australia and use a hot vulcanisation process to produce a robust, premium hose. Talk to us about your requirements and we’ll help you choose the right hose for the job.
