About the 4-inch Flex-Tube PU
The 4-inch is the workshop size of the Flex-Tube PU: it fits standard 4-inch dust collection ports and is the polyurethane upgrade when sawdust turns into chips. Clear ether-based polyurethane with a .033-inch wall and a rigid yellow ABS helix that takes the wear; better abrasion resistance and a wider temperature range than PVC, stocked in 12, 25, 50, and 100 ft.
Stocked in 12, 25, 50, and 100 ft lengths. Each price is for one hose of that length.
Where you'll see the 4-inch PU
- Dust collection at 4-inch ports — sawdust, chips, shavings
- Industrial vacuum cleaning and material handling
- Food-grade granular transport
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.
