Flanged Tee Branch 12ga

Flanged T-Branch duct fittings are standard with industry-standard Angle Flanges on both ends. The flanges are retained via a vanstone lip so that bolt holes can easily be aligned with those on existing flanged connections.

12 gauge steel material provides extra durability for high wear applications. 12 Gauge Y-Branches have leak-free, solid welded seams; elimination of air leakage makes a dust collection system more efficient, providing savings on energy costs.

When ordering tees, specify A, C. The two “A” ends must be the same dimension, however “B” must be equal to or smaller than the “A” dimension.
Use the following formula to determine length: L = C + 8".
Available in galvanized steel or carbon steel
Available with QF ends in diameters up to 24", flanged diameters up to 72", and other end types
Other material gauges available include standard 22 and 20, 18, 16, 14 and 10
Flange gaskets available

Contact Nordfab or your local Nordfab dealer for assistance with optional end types, larger sizes, and material / gauge options.
