Flanged In Cut 30°

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

Our Flanged In Cut duct fittings are used to add ducting into existing lines of industrial ductwork. In-cuts are also known as “saddle taps”.

In-cuts are standard 30° or optional 45°.

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

When ordering In Cuts, specify A and C diameters.
Saddle length and width = 3" all directions from Branch Tube C.
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
Other material gauges available include 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.
