Collection: Couplers

Radon Fan Couplers

Couplers are short pipes or tubes with a socket on one or both ends used to join 2 pipes together. Most of our radon fan couplers are manufactured by Fernco, with the exception of our 3” x 3” black, and the 4” x 3” black which are made by Eastman. The radon fan couplers also reduce vibration noise and are fan model specific. Some models come in multiple colors and sizes so you can always find the right flexible coupling for your project. For more information on any of our Eastman or Fernco couplers, browse our shop below. You can also reach out to us to speak with a member of our expert team.

Reminder: Contractors, remember to sign in before beginning your order!
