Reducing Y pieces are manufactured to order from 0.7mm galvanised mild steel. The ends are male, meaning they are slightly smaller than the nominal size to enable them to slip inside rigid spiral and/or flexible ducting.
To order the correct size reducing Y piece/s, please select a size from the list below that represents dimension A in the drawing. Dimension B and the required angle can be selected on the following page.
