Tuff Tube®
Tuff-Tube®
to Protect your Equipment from Extreme Spouting Wear
Tuff-Tube® Spout Lining
The Tuff-Tube® lining system is a patented urethane spout liner manufactured by Sioux Rubber & Urethane with our specially formulated Endurawear® Urethane. Tuff-Tube® can significantly reduce the abrasion of grain, seed and fertilizer handling, extending the life of your equipment. In a season or less grain will cause extreme wear in your spouting that can ruin your spouting. The Tuff-Tube® lining system is an excellent answer to high maintenance costs and the constant replacement of steel spout. The Tuff-Tube® spouting liner can be rotated 120° – 180° to present additional wear surfaces. Completely used liners can be removed and replaced using the same spout, saving you the expense of having to purchase new each year. Tuff-Tube spout liners are available for any standard spout diameter up to 24” and in lengths up to 20’ for new or existing spouting applications. The Tuff-Tube® protects your valuable machinery and improves your bottom line!
Seamless Spouting Application
This is a seamless spouting system that prevents objects from getting in-between the liner and spout that creates buckling, plugging and peeling issues. Our lined spout elbows have a permanently bonded liner that matches up to the Tuff-Tube® liner for total spout protection. Lined spout elbows are available with and without tapered leading edge.

Tuff-Tube® is effective and convenient for spouting applications including:
- Feed, Seed and Grain Processing
- Aggregate
- Mining
- Fertilizer
- Frac Sand
Conveyed material cannot force itself under lining:

Tuff-Tube® slip-in Endurawear® Urethane liners counter material wear to spout lining, saving time, money and extending useful life of equipment by reducing down time. Worn liner can be rotated 120° – 180° to present addition wear surface. Completely used liners can be removed and replaced using the same spout.
