Flanged Tee Branch

Flanged Tee Branch

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

Our 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.

  • 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 and 304SS (as shown below) or optional 316SS or carbon steel
  • Available with QF ends in diameters up to 24", flanged diameters up to 72", and other end types
  • Optional gauges 18, 16, 14, 12 and 10
  • Flange gaskets available

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