Duct Seal 1D (110–125mm Duct) TDUX-125
The TDUX-125 is the largest inflatable duct seal in the TDUX range, engineered for permanently sealing 110–125mm telephone cable ducts to prevent water ingress into manholes and exchange vaults. This innovative wraparound system provides a reliable, long-term seal and is suitable for use with plastic, concrete, or steel wall-feedthrough duct systems. It accommodates both polyethylene and lead-jacketed cables, and adapts easily to oval or round ducts.
Installation is fast and straightforward using the Duct Inflation Tool, even in tight or water-filled spaces. The TDUX-125 delivers a water- and airtight seal up to 50 kPa and can be used for vacant ducts or ducts containing one or two cables. A clip is available for sealing multiple cables. Designed to be non-toxic, environmentally friendly, and highly resistant to chemicals and bacteria, this seal also offers easy removal when required.
