Self-Sealing Steel Duct & Fittings

Self-Sealing Steel Duct & Fittings

Quickly install a duct system in residential or light commercial settings using self-sealing duct and fittings. They have built-in gaskets that form a seal at the joints and are secured with screws for easy assembly, and the duct snaps together along its length without the need for specialized tools. Run a length of duct and add fittings that bend, branch, or cap airflow to deliver heating and cooling where it's needed. Steel duct is typically a better choice than PVC for high temperature applications, and is generally lighter in weight.


Create a straight run of duct with this pipe. It's typically used to branch off trunk lines as well as to deliver return air.


Transition between larger and smaller ductwork with these reducers. They have a different diameter at each end.

End Caps

Cover duct ends with these caps to terminate a run of duct, protect duct ends, and provide a finished look on your ductwork.

Collars with Damper

Balance airflow and prevent backdrafts to help maintain efficiency in duct systems with these collared dampers. Also known as start or starting collars, they have a gasketed flange that seals around cutouts in trunk lines, floors, walls, and ceilings and also have a damper, which is an internal disc or wafer, that can be rotated to adjust airflow. These fittings are commonly installed at an easy-to-access location in each branch of a system.

90° Elbows

Change the direction of airflow at a right angle with these 90° elbows to move air up, down, or around corners. They will cause some reduction in airflow.


Split airflow off a trunk or branch line and redirect it at a right angle with these tees. They have a free flow design that forms a gentle angle to help maximize airflow. They're often used for exhaust applications.
