The Slurryflex DT-Series Trunnion Dredge Hose is a steel-reinforced hose designed to meet the rigorous demands of cutter dredging.

Instead of the usual spring wire reinforcement of standard slurry hoses, this trunnion or ladder hose has integral steel rings that allow for flexibility under high loads and full vacuum.

The internal wear liner provides resistance from abrasive material such as soft clay, sand, and silt with high solids concentration. The outer cover protects against UV, ozone, and external wear. Flexible rubber construction provides rotation or movement on site, and minimises misalignment and vibration.

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
