About the 12-inch Flexadux TR T-7
The 12-inch is the largest stocked Flexadux TR T-7 — the duct-cleaning and large-ventilation size — as a 25 ft length. Medium-weight black thermoplastic rubber on a spring steel wire helix that holds a 12-inch bore round under vacuum, with a smooth interior and the moisture, UV, and chemical resistance of the line.
Stocked as a 25 ft length. Each price is for one hose of that length.
Where you'll see the 12-inch T-7
- Commercial duct cleaning and HVAC service work
- Large ventilation and pollution-control runs
- Bulk material transfer
If the hose will be dragged across floors or concrete, the Flexadux TR T-7W is the same construction with an added yellow polypropylene wearstrip against abrasion. For lighter duty at lower cost, see the PVC and polyurethane Flex-Tube lines.
