This series of reusable air-tight aluminum duct couplings are ideal for both temporary and permanent installations.

• The coupling body, rubber gasket, and stainless steel fasteners are essentially impervious to corrosion.
  
  
• No special tools are required to install the couplings except a Allen-head wrench.
  
  
• To reuse, remove the 2 aluminum halves of the coupling and carefully cut the gasket. The coupling can then be reused with a new rubber gasket.
