Duct Seal 1A (60–110mm Duct) TDUX-90

The TDUX-90 is a high-capacity inflatable duct seal engineered for sealing 60–110mm telephone cable ducts. Designed to protect critical telecom infrastructure, this advanced wraparound system prevents water from entering exchange vaults or manholes. Developed for use with plastic, concrete, or steel wall-feedthrough systems, the TDUX-90 is compatible with polyethylene and lead-jacketed cables, and adapts to both round and oval ducts.

Its flexible and reliable design allows for quick installation with a Duct Inflation Tool, even in tight or water-filled spaces. The TDUX-90 creates an airtight and watertight seal up to 50 kPa and is suitable for both vacant ducts and ducts with one or two cables. A clip is also available to seal around multiple cables. Resistant to chemicals and bacteria, this environmentally friendly and non-toxic solution ensures long-lasting protection with the added benefit of easy removal.
