Duct Fittings & Components
Duct fittings from AEROVAC Duct range in function, length, and diameter. If you are looking for flanges, elbows, branches, double branches or, y-branches we have many types of duct fittings in stock as well as custom fabrication capabilities. Many of our duct fittings are in the list below.
Flanges (Angle Rings)
Pressed and rolled steel flanges (angle rings) are used widely in joining ductwork together in dust and fume control work. All flanges/rings are of unpainted black steel. All sizes are stocked for immediate shipment.
Flanged Duct
Flanged duct is available in 5′ or 10′ lengths. It is also available fully seam welded or in lock seamed joints. Lock-seamed is only available in 5′ lengths. Standard flanges are galvanized. Available in stainless steel or black iron.
Elbows – Flanged
Standard radius (1.5) and long radius (2.5) flanged elbows are available in 30 to 90-degree elbows; from 24 to 48 in diameter; and 16 and 18 gauge stainless or galvanized steel.
Elbows -Flanged, Pleated / Non-Welded
The non-welded, unidirectional, pleated and flanged elbow is very cost efficient in systems where a small amount of leakage is acceptable (the wood industry). Available in galvanized steel only.
Elbows – Flaged, Pleated /Welded
The welded, unidirectional, pleated and flanged elbow provides good, all around usage. Available in galvanized steel only.
Branches (Tee on Taper)
Single branches (Tee on Taper) are available in 30 and 45-degree angles; 24 to 48 diameter; and 18 to 16 gauge galvanized or stainless steel. Heavier gauges and larger sizes are also available.
Double Branches (Tee on Taper)
Double branches (Tee on Taper) are available in 30 and 45-degree angles; 24 to 48 diameter; and 18 to 16 gauge galvanized or stainless steel. Heavier gauges and larger sizes are also available.
Y-Branches
Flanged Y Branches are available in 30 and 45-degree angles; 24 to 48 diameter; and 18 to 16 gauge galvanized or stainless steel. Heavier gauges and larger sizes are also available.
In-Cuts
Flanged in-cuts are available with Tee’s in 30 and 45-degree angles; 24 to 48 diameter; and 18 to 16 gauge galvanized or stainless steel. Heavier gauges and larger sizes are also available.
Cut-offs & Blast Gates
Flanged cut-offs and Blast Gates are available in 4 to 22 diameters in both galvanized and stainless steel. Blast gates are constructed from 14 gauge galvanized or stainless steel.
Reducers
Flanged reducers are available in 24 to 48 diameters (priced by the large end) in 18 and 16 gauge galvanized or stainless steel. Available in heavier gauges and larger sizes.
Rectangle to Round Transitions
Flanged Rectangular to Round transitions (hemmed) are available in 24 to 48 diameters (priced by the large end) in 18 and 16 gauge galvanized or stainless steel. Available in heavier gauges and larger sizes.
