  • 90-degree turn for 8-inch duct runs
  • Galvanised steel resists corrosion in HVAC systems
  • 22-gauge wall handles up to 42 in wc pressure
  • Rolled-edge ends simplify clamp connections
  • Weighs 6.1 lb for easy handling

90 Degree Elbow 8 in Galvanised Steel

Nordfab 8040400004 is a 90-degree duct elbow made from 22-gauge galvanised steel for an 8-inch nominal duct diameter. It has an 18 1/4-inch overall length and a 1 1/2-inch centreline radius with rolled-edge ends. The fitting weighs 6.1 lb and is rated for 2 to 42 inches water column pressure. It installs in HVAC systems requiring a right-angle turn.

Suits installers needing a standard 8 in 90-degree

The elbow fits ducts with an 8-inch inside diameter and matches the same inlet and outlet size. It is not for systems that require a different angle, a different duct diameter, or a non-rolled edge connection. Buyers needing a straight coupler or a reducing fitting should choose another part.

8 in duct diameter with 42 in wc max pressure

The 8-inch diameter and 42 inches water column maximum pressure rating determine whether this elbow matches the ductwork and fan specifications. Verify both values against the system design before ordering.

Questions about this item

Is the 8 in duct diameter the only size this elbow is offered in?

Yes, this Nordfab elbow is produced for an 8 in nominal duct diameter with an 8 in inlet and outlet.

What does the 22 ga steel thickness mean for airflow resistance in a real installation?

The 22 ga galvanised steel keeps the internal surface smooth, so the 90 degree turn adds minimal friction loss at rated pressures.

How does the rolled-edge end type affect the maximum 42 in wc pressure rating?

The rolled edge provides a secure clamp connection that maintains the 42 in wc maximum pressure rating without leakage.
