If you have a random mitigation fan from Fantech RN 4 ec, it needs two 6" couplings. However, you CANNOT use 6" PVC couplings because those pipes have a 6.625" outer diameter. You must use coupling for a pipe with an OUTER diameter of 6". 5" clay pipe is correct.
This coupling WILL connect the Fantech RN 4 EC to a 4" PVC.
