Flanged Y Branch 18ga

Nordfab manufactures ducting for use in dust, mist, and fume collection systems.

Nordfab® flanged duct branches in Y shape (sometimes called “true wyes”) are standard 60º between legs, optional 90º. Durable 18 gauge steel construction. Standard with our rotational Angle Flange (AFL) ends.

When ordering Y Branches, specify A, B, C.

Both B & C each must be at least 50% of A, with B or C being at least 80% of the opposite leg.

Use the following formula to determine length: L = A + 4”.
