OATEY 43651 – Frequently Asked Questions
1) Will the Oatey 43651 Twist-N-Set flange fit inside cast iron pipe, or only PVC?
It installs inside 4 inch pipe and the gasket expands to seal in service weight, heavy weight and no-hub pipe, so cast iron is covered. That is the main reason people reach for it: replacing a broken cast iron toilet flange without cutting out the pipe. The flange body itself is PVC.
2) Do I need a torch, solvent cement or special tools to set the Oatey 43651 closet flange?
No. It is a gasketed, no-tools install, twisted into place inside the pipe. No solvent welding, no lead and oakum, no caulking the joint. That makes it a practical repair in a finished bathroom where you cannot get a torch or a saw down to the pipe.
3) Does the Oatey 43651 come with the sleeve, or do I have to order that separately?
The sleeve is not included. Order the flange knowing you may need to source that piece separately for your repair.
4) Is the Oatey Twist-N-Set a straight flange or an offset one?
Straight. The outlet runs in line with the pipe below it, so it does not shift the closet bolt centers off the existing drain. If your toilet needs the waste moved toward or away from the wall, a straight flange will not do that for you.
5) For a rental turnover with a broken toilet flange in a slab, is this the repair flange to use?
It suits that job well. The 43651 drops inside the existing 4 inch pipe and seals with an expanding gasket, so you are not breaking concrete or cutting cast iron to get a fresh flange. PVC body, white finish, and it is specifically made to replace broken cast iron closet flanges.
6) Will the Oatey 43651 restrict drain flow since it sits inside the pipe?
It uses a smooth, unrestricted flow design, so the inside diameter is not choked down the way a patched or sleeved repair can be. That matters on a 4 inch closet bend carrying the whole toilet discharge.
