Duct Seal 1C (35–45mm Duct) TDUX-45

The TDUX-45 is a high-performance inflatable duct sealing solution designed for permanently sealing 35–45mm telephone cable ducts. Part of the innovative TDUX series, this flexible wraparound system prevents water ingress into exchange vaults or manholes, protecting sensitive infrastructure from flooding and damage. Suitable for use with plastic, concrete, or steel duct wall-feedthrough systems, the TDUX-45 accommodates polyethylene or lead-jacketed cables and is compatible with both oval and round duct configurations.

This robust seal can be installed quickly, even in congested or water-filled environments, using the Duct Inflation Tool. It provides a water- and airtight barrier up to 50 kPa and is ideal for sealing vacant ducts or those containing one or two cables, with an optional clip available for multi-cable applications. Designed with durability and environmental safety in mind, the TDUX-45 is resistant to chemicals, bacteria, and is non-toxic.
