Easily fits inside a 4 inch diameter pipe. The gasket twists up the threaded flange pipe to expand as needed. It will fit on cast iron or pvc pipe. Easy to install. Seals firmly without leaks. The fit is so snug with the gasket against the inside of the pipe that it really cannot be removed without twisting it back out. I prefer the iron over the plastic because I have broken plastic flanges before. This one is more durable.

Can I say how easy, convenient, solid and durable this toilet flange is. It's a cast iron material in black, with a twist n set replacement flange for a 4 inch iron pipe with a rubber gasket and no tools required. Make sure to follow the tag installation instruction with the tilt and twist flange while the rubber gripes into pipe perfectly. It's simple and fast replacement. It's more difficult having to remove the toilet while this flange takes no time at all for placement. I've only used it for cast iron pipe as directed.

According to my husband/plumber, this was very easy to install. Our rental property was built in the 1960's and we have always had many difficulties repairing/replacing every thing in this home. This worked really well. It slipped easily into the existing pipe and he was literally able to twist it into place and it was set. The bottom is tapered and when you twist it the rubber compresses to fit snugly.

This Oatey toilet flange is NOT your everyday purchase and item used for the home however when you have a need to replace a well worn lead bend this ingenious cast iron “twist-N-set” toilet flange plays nicely in such a repair. My lead bend project involved me calling in a professional plumber and planning a method of repair which would NOT make an already stressful and difficult project into something worse. I personally prefer cast iron repair parts over pvc and Oatey came through once again with a thick quality manufactured toilet flange. While I have used both pvc and cast iron toilet flanges in the past I’ve had longevity issues with pvc which was also substantiated by plumber friends. Only other parts required for this repair were a few Fernco couplings, a tight radius 90 degree thick cast iron bend, and a few 4-inch diameter cast iron couplings custom cut with the plumber’s soil pipe chain cutter. Whole project took just 3.5 hours start to finish leaving me with just a hole in the ceiling which my good friend and work associate to patch and spackle at a later date. This was definitely NOT a homeowner project simply because it is a technique sensitive repair acquired from many years and numerous iterations of lend bend replacement and repairs. Caveats include setting aside a day (or more) for this type repair, carefully choose a licensed bonded plumber with a warranty, and finally shop around as prices for this vary all over the map. Here in NYC prices were around $1500-$2000 so be sure and ask around and negotiate if possible. Finally, thank you Oatey for this toilet flange.

I have not installed this item as of yet, but will be doing in a few weeks. I use our Florida condo for fishing tournaments and will be going soon. I plan on installing this toilet mounting ring as old metal was broken at purchase of condo. It looks very easy top do and if it works as designed I can take out my reworked job to prevent leaks. I purchased new toilet from Home Depot and picked up FluidMaster no wax seal kit and this will make reinstalling toilet on new metal ring easy as pie.

Toilet flange repair or replace When I lifted a 1958 toilet in my 11 apartments building to check whay the ceiling in downstairs bathroom have water marks I find out that the old brass close flange sealed with steel wool and lead had cracked which I ended up destroying it in the process of its removal. I was trying to reinstall the same toilet and end up with new one for efficiency reason, also I needed a new flange since I remove the old brass one do to crack in the lead seal (I could possible fix it with new wax ring but why should I take risk I needed permanent solution), and I come across this one in the Home Depot. My waste pipe is 4 inch cast iron pipe. This unit fit nicely into the pipe, and was very easy to twist to get the rubber gasket to move up and expand around the 4 inch cast iron pipe, seating and sealing against the pipe. It seems to have provided a good seal, and created a solid support for the toilet bolts. Allowed me to properly seat and reinstall the new toilet, Simple, efficient and quick to use no tools needed or any extra sealant or glue. Adjust the rubber nut for slightly tight fitting in to the pipe Insert it in the pipe with in mind that it will go down as you tighten it, tilt ever so slightly so the rubber gasket gets a grip on the side of the drain pipe, and turn to expand it until is tight like any nut or bolt. The flange unit itself tapers to a wider outside diameter toward the flange end, which is how the gasket expands to provide a tighter seal creating a nice and stable installation. In the future I will not use anything else to fix the toilet flange, this is the perfect solution for those oops situations.

Oatey Twist-N-Set 4” Cast Iron Floor Closet Flange is designed as a replacement for broken cast iron flanges. The flange is positioned into the existing cast iron or lead piping and the tapered outside diameter of the outlet causes the rubber gasket to expand when rotated, compressing the rubber seal against the piping. No tools required. I used this cast iron replacement flange to repair the toilet drain in our 100 year old home. When previously replacing the toilet I noted with dismay that there was no flange on the drain pipe; the first indication of an issue being the toilet lag bolted to the floor. As it had not been leaking, and showed no evidence of leaking, I carefully placed a new wax ring and set the new toilet, and crossed my fingers. We only have one bathroom and I wanted to think over my options, so I had no choice but to set the new toilet. When I saw this cast iron replacement flange option I knew I wanted to try it over the plastic options available. After removing the new toilet, cleaning the flange area of wax, scraping/wirebrushing the lead drain pipe interior smooth and clean, and using a hammer to gently reshape the top of the lead drain pipe, I then dry fit the flange. I noted the flange outlet was too long, making contact with the bottom of the lead drain pipe and not allowing the flange to sit on the floor; the lead drain took an immediate 90 degree turn to the cast iron stack. I took some measurements, made some more dry fits, and decided to cut 1” off the outlet of the flange. Dry fitting after the cut showed the flange now sitting flat to the floor. I then spent about 30 minutes carefully coaxing the flange into position due to the rubber gasket already being expanded nearly to its maximum diameter. I also added wax to the underside of the flange above the rubber gasket as a secondary seal to the topside of the lead drain. I got good squeeze out, it isn’t going to leak. Yes, the best (proper?) method to fix this would be to lead a new flange into place with old-time techniques that I once helped my father with, but that is expensive and I don't have the necessary supplies and equipment. This worked, and is a good fix. I spent 4 hours on this repair. Don’t plan on using construction screws with a typical diameter head to fasten the flange to the floor as the holes in the cast iron flange are quite large. Luckily I had some old bronze wood screws lying around that worked. I also modified some washers with a punch and vice to concave them to mate to the countersunk flange holes, allowing me to use the smaller head screws. I had to use the short bronze screws over the lead drain area so as not to punch a hole in it. A new wax ring, careful resetting of the toilet, and securing with the proper bolts completed the installation. It should now be good for quite some time, at least as long as I will be using it. (I found it necessary to grind the toilet bolt heads, allowing them to rotate further, so as to have more contact area with the flange slots.) For a more typical installation, it takes some planning, luck, and probably more than one attempt to get the rubber gasket firmly compressed and seated while also having the toilet bolt slots properly positioned. Considering the alternatives, I consider this to be an easy secure installation. Be sure to have the rubber gasket securely compressed to eliminate sewer gas and moisture issues. Be sure to follow all plumbing code regulations while installing this replacement flange. One year limited warranty. Made in Taiwan.

My abode is nearly as old as I am. Which, when translated, means that the likelihood of it having cast iron plumbing is exceedingly high. In my days last century, I was known to rock and roll. However, this is not anything that I wish to do while sitting on the toilet. The timing of this gift was excellent. The broken flange needs repair/replacement. The installation really needs to be looked at in two phases. Pulling the toilet, cleaning off the wax ring, getting rid of the old cast iron flnage, and cleaning up the area deserves a one star rating. The installation of the actual flange itself coundn't be easier (unless you hired a plumber). Screwing into the existing concrete flooring was a snap. Refilling the space with a portland cement product was a 3 star activity. Having broken a couple of replacement PVC flanges, I am totally down with this cast iron product.
