Duct flange gasket strip seals between duct flanges so joints stay airtight and dust-tight.
Stick it to one flange before assembly.
What is a duct flange gasket strip?
Duct flanges, G-clamps and gaskets join rectangular ductwork. The flange profile fixes to each duct end, the gasket sits between the flanges, and clamps hold the joint tight between the corner bolts.
An airtight joint saves fan energy and stops dirty air leaking into ceilings. Therefore, use a gasket on every flange joint.
