Designed for use in industrial hose and ducting assemblies, the Thermal Flex Reducer 2 3/4 x 3 is a transition fitting manufactured by Tacna International under the Thermal Flex product line. It connects two different hose or duct diameters, 2¾ inch and 3 inch, allowing for diameter changes within a system without additional adapters or custom fabrication.
This reducer is suited for thermal management, ventilation, and exhaust routing applications where flexible ducting requires a stepped connection between mismatched component sizes. As a Thermal Flex component, it is built to integrate directly with compatible flexible duct products in the same line.

For joining mismatched duct or hose sizes, this reducer transitions between a 2 3/4 inch diameter and a 3 inch diameter so you can make that size change in the run without adding extra adapters or having something custom made.
