Flanged Reducer 14ga

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

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

14 gauge steel material provides extra durability for high wear applications. 14 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. 14 gauge Reducers are available in diameters from 8" to 50".
Rotational Angle Flanges retained vanstone lip is standard. If welded flanges required, clocking must be specified.
Available in galvanized steel and 304SS (as shown below) or optional 316SS 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, 12 and 10. Diameters up to 72".
Flange gaskets available
