Fernco donuts work off of compression, therefore your dimensions need to be very specific and within 1/8" or else the product will fail. Please contact Fernco Customer Service with your specific application details, 800-521-1283.

If you are trying to couple ABS to Cast iron and you can join it at a bell in the cast iron this is the only way to go. Makes for a very clean and tidy connection! I would recommend it to anyone doing this kind of plumbing project. I have used these couplers a few times always easy to use and the finished job is perfect.
