About Duct Couplings and Adapters

What Are Couplings and Adapters?

Within HVAC ductwork you will find many instances where connecting fittings are required to join two vents/pipes. Couplings generally imply a connector that joins two similar sized vents. Contrast that with an HVAC adapter, which serves as a reducer or increaser to connect different-sized venting or pipe.
