Flexible Coupling - 3.0" x 6.0" - Black

They were true to size and the only place I could find them. Delivery was timely and they seem of good quality.

I used this to connect a 3" pvc pipe to one end of a radon fan housing. It fit perfectly.

I received a Fernco 1006-43, which is 5.59" diameter on the wide end. It's possible with a little difficulty to stretch this out to fit over the 6" flange on the larger radon fans.I expect all the couplings used for this application are like this - even RadonAway's 3" x 6" coupling is advertised as a Fernco coupling. So, I don't think this is the seller's fault, but it's annoying to get this coupling onto the fan because it's just a bit too small.

Worked great! Most satisfactory.

Fast shipping and excellent deal compared to what special order was from my local big box stores. Nobody had a 6“ x 3“ in stock. And I got a name brand part! I was expecting generic or foreign made since the brand was not specified. Thank you!
