Spiral Reducers

Spiral Reducer

Galvanised steel Spiral reducers designed to connect two different sizes of spiral pipe with a smooth, tapered transition between duct diameters.

The tapered design provides a gradual change in duct size, helping maintain efficient airflow through HVAC and ventilation systems.

Manufactured with ball-swaged connections, stitch-welded seams and factory-fitted rubber gaskets for a strong, secure and airtight connection.
