Flanged Reducer 12ga

Flanged Reducer 12ga

Nordfab Reducers provide easy transition from one size of duct pipe or fitting to a smaller size.

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

  • When ordering reducers, specify dimensions of both A and B ends.
  • Rotational Angle Flanges retained vanstone lip is standard. If welded flanges required, clocking must be specified.
  • Available in galvanized steel or carbon steel
  • Available with QF ends in diameters up to 24", and other various end types
  • Optional gauges standard 22 and 20, 18, 16, 14 and 10. Diameters up to 72".
  • Flange gaskets available
