About the 3-inch Flex-Tube PU
The 3-inch is the largest small-bore Flex-Tube PU — 25, 50, and 100 ft rolls of polyurethane for the runs just below the 4-inch dust-port size. Clear ether-based polyurethane, .033-inch wall, rigid yellow ABS helix as a wearstrip; abrasion resistant and flexible from -40°F to 200°F.
Stocked in 25, 50, and 100 ft lengths. Each price is for one hose of that length.
Where you'll see the 3-inch PU
- Small dust collection branches and vacuum lines
- Granular and food-grade material transfer
- Industrial vacuum cleaning
Compared with PVC hose like the Flex-Tube PV, the Flex-Tube PU has better abrasion resistance, higher tensile strength, and a wider operating range (-40°F to 200°F vs. 20°F to 160°F). For the most abrasive material, the heavy-wall Flex-Tube PU 60 HF is the next step up.
