The special Y piece is designed to enable connection of different diameter ducting to a rigid joining piece without the need for seperate reducers. There is a centre flange of one diameter and 2 flanges of a smaller diameter in the Y shape. The Y piece can therefore be used for moving one large to 2 small ducts or 2 small to one large. It is in stock with a main flange diameter of 6", 8", 10" or 12" as follows:
1 x 6" - 2 x 5"
1 x 8" - 2 x 6"
1 x 10" - 2 x 8"
1 x 12" - 2 x 10"
