Oatey GIDDS-173390 43539 Replacement Flange Forcast Iron, 4 Inch, PVC

There are a couple different styles of this contraption, and I like this version the best. The toilet gasket I was replacing (cracked) was mounted on a concrete slab, so working from the underneath wasnt feasible. The hardest part was heating the old flange just enough to pull it out, without damaging the PVC pipe which is left behind. Another version works by twisting the flange on a rubber gasket. As the flange is twisted, the rubber gasket is forced to expand and creates a seal. This version, however, works by crunching the rubber gasket, forcing it to expand. This is far superior as you can correctly lay the orientation of the flange, then tighten the gasket as necessary without turning the orientation. I believe this version requires an allen to tighten the flange, which isnt always ideal for those without every shape tool in their inventory.

I was kinda nervous about this sealing into my old home floor pipe. The floor pipe isnt perfect round, it has bulges and dents, but this sealed. I YouTubed the installation so I had a lot of faith in how to do it.

Worked great, did what it was exactly intended to do. Very, very easy install. Just make sure its aligned, and measured from the wall for correct rough in.

Works well

Worked great for my old cast iron pipe. Very tough material and was impressed with this item. Would definitely recommend.

Had a 4 cast iron drain pipe with a mostly rusted flange. Watched my son-in-law drill and chisel it out and then we replaced it with this part. Tightened it up after securing it to subflooring and reattached the toilet. The toilet hasnt felt this stable in many years. Perfect replacement!

It’s works perfectly and very easy!

This flange saved the day. I tried all different sizes and shapes but this was the best. It fit well with the old cast iron pipe and was tight and durable. You won’t be disappointed!

I am so glad they make a fitting that works on cast iron.

This is the best replacement ever. Easy to install.
