Vacuum-Rated Large-Diameter Aluminum Tubing

Vacuum-Rated Large-Diameter Aluminum Tubing

Vacuum-Rated Large-Diameter Aluminum Tubing

Move bulk material, exhaust gas, or suck up dust in powerful vacuum systems—this tubing is large enough to transfer pellets and debris and strong enough to withstand nearly perfect vacuum. Made of aluminum, it’s lighter weight than steel tubing, so it’s best when you need to reduce the weight of your system. It also resists corrosion from frequent rinsing, humidity, and rain.
