Why is transparent hose usually preferred for gold dredging?
When you are operating a suction dredge in a river, the hose runs from the suction nozzle at the river bottom and up to the dredge pump. If gravel bridges and blocks the hose, you cannot easily determine where the blockage is in a non-transparent hose. When you use a transparent hose you can see exactly where the flow has stopped and locate the blockage quickly. It also gives visual confirmation that material is flowing when the pump is running.
Is lighter and more flexible always better for gold dredging suction hose?
Not always — but for most alluvial gold suction applications, yes. The operator is carrying the hose on their body while doing physical work in cold water — light weight reduces the load on the shoulder and a flexible hose drapes more naturally in this position than a stiff one, particularly in cold river water where stiffer PVC becomes harder to position comfortably. The tradeoff is that the thin PVC wall that provides this flexibility and light weight is less durable than heavier alternatives under abrasive conditions. For smooth river gravel in water this is acceptable. For sharp, dry, or highly abrasive material it is not.
Can I use this hose for dry material or dust collection?
The SH Series is rated for dust collection, but it is not suitable for dry abrasive material suction or sharp material. The thin PVC wall will wear quickly under sustained abrasive conditions. For dry abrasive material handling, contact United Flexible for a more appropriate product.
How does the Tigerflex SH Series compare to heavier clear PVC hoses for alluvial gold dredging?
Other types of clear PVC hoses are sometimes used or offered as an alternative to the Tigerflex SH Series for gold dredging. They tend to be heavier and less flexible — particularly in cold conditions — which makes them more cumbersome and difficult to handle. The Tigerflex SH Series is specifically engineered as a suction hose with Cold Flex PVC for sub-zero flexibility, making it the most practical option for alluvial gold dredging use.
What fittings are compatible with the Tigerflex SH Series?
The SH Series is compatible with any industrial hose fittings which fit using an internal hose tail matched to the hose bore size. Contact United Flexible with your bore size and connection requirements for a specific recommendation.
