Frequently Asked Questions
Which end of a Reducer is crimped?
The smaller end is crimped so the fitting can reduce the duct diameter in the direction required by the duct layout, and for nesting to another piece if needed.
How is a Reducer different from an Increaser?
A reducer transitions from a larger duct to a smaller duct and has the smaller end crimped; an increaser transitions toward a larger duct and has the larger end crimped.
How do you step down from a larger duct to a smaller one?
Reducers connect a larger round duct to a smaller downstream duct size; the smaller end is crimped for the specified connection.
Which Reducer sizes are documented?
Available transitions are 4 to 3, 5 to 4, 6 to 4, 7 to 4, and 8 to 7 inches.
