About the 6-inch Flex-Tube PU
The 6-inch is the Flex-Tube PU stocked in the most lengths — nine, from a 5 ft replacement piece to a 100 ft run — because six inches is a common leaf vacuum hose size and the PU is the abrasion-resistant, cold-weather choice for it. Clear ether-based polyurethane with a .035-inch wall and a rigid yellow ABS helix as a wearstrip; it handles leaves, wood chips, and bark mulch, and stays flexible to -40°F.
Stocked in 5, 6, 8, 10, 12, 15, 25, 50, and 100 ft lengths. Each price is for one hose of that length.
Where you'll see the 6-inch PU
- Leaf and lawn debris collection on walk-behind and tow-behind vacuums
- Mulch blowing and wood-chip handling
- Dust collection mains and industrial vacuum lines
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.
