About the 4-inch Flex-Tube PU 60 HF
The 4-inch is the most-bought Flex-Tube PU 60 HF: the standard dust-port size, in the heavy 60-mil wall, stocked in six lengths from 6 to 100 ft. Clear heavy-weight polyurethane with a rigid blue ABS helix as a wearstrip — the upgrade from standard PU when wood chips, grit, or grain wear a lighter hose through. Extremely abrasion resistant, puncture and tear resistant, and flexible from -40°F to 225°F.
Stocked in 6, 8, 12, 25, 50, and 100 ft lengths. Each price is for one hose of that length.
Where you'll see the 4-inch PU 60 HF
- Dust collection at 4-inch ports where the material is abrasive — chips, grit, shavings
- Grain vacuuming, mulch blowing, feed transfer
- Lumber mills, sand blasting recovery, industrial vacuum
If your application is lighter material or lower volume, the standard Flex-Tube PU offers the same polyurethane advantages at a lower weight and cost. The PU 60 HF is the heavy-wall version — a 60-mil wall for more abrasive material and higher-demand equipment.
