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

Good product and well made. Problem was it would not fit my 4 in cast iron pipe. All cast iron pipes get rusty inside and as a result the flange would not fit inside the 4 in. opening. I tried to grind some of the rust away to see if it would slide in - no luck. Ended up having to use Sioux Chief 4 in. PVC DWV Gasket Closet Flange. Disappointed, and could not return because it is now dirty and scrapped up. Costly lesson.

Just what I needed for my 4 cast iron pipe tighten the 3 bolts down and tapcon it to the concrete floor and was good to go.

Works well

Easy to install almost for any situation, and works like charm. Superb design.

It feet to my old style cast iron pipe. Condition is good.

These work good. Have used a few over the years. Just do not over tighten the Allen bolts. That is to seal it to the pipe not hold the whole shooting match to the floor. Screw the flange down well and it is stronger to put the closet bolts in the two small notches than the big slot. Place your bolts in the notches and get them spaced off the wall evenly before you push it down in the pipe and you should be...good to go.

This thing was/is amazing. Fit perfectly into the cast iron pipe and tightened as tight as the old cast iron flange used to be. Toilet is as tight as it could be and it doesn’t wobble anymore!!! Very happy with this....

Easy to install. Made it easy to connect to the lead pipe in our old house. What else can I say except the poop goes down and water doesnt leak out. lol

This piece really seemed to be perfect for my particular application, where the person who lived in this house previous (and it is an old 1930s era house) had really done a number on installing the old toilet. When I pulled the old one off (made in 67..finally had the tank crack and flood the bathroom), there was no flange of any kind. The guy had used the lead-trick on top of the iron pipe to form a flange...the bolts for the bowl were screwed down into the floor..and of course broke off when I removed the nuts. SO...after much research, and really good reviews on this piece, I ordered it. It fit into the 4 pipe quite well and snugged down very nicely on my practice try...maybe a mistake, because one of the nuts somehow cross-threaded, I think, and I couldnt get it to go either way. So when I went to do the install, I could not tighten all 3 allen-screws down like I wanted. At any rate, I was able to put 3 really nice long wood screws into the floor to secure the flange, and the new toilet fit on it perfectly...level...and we are off and running...well...off and something!!

Easy to install
