OATEY 43621-FASTSET – Frequently Asked Questions
1) What does the 4 inch offset on the Oatey 43621 Fast Set toilet flange actually do for me?
The offset lets the closet flange sit off-center from the drain pipe, so when the stub-out doesn't land where the toilet needs to be, you can still set the bowl without moving the pipe. Oatey builds the 43621 with a 4 in. offset specifically to give a margin of error on drain pipe to flange alignment. That's the common fix in remodels where a wall moved or the rough-in is short.
2) How does the Oatey 43621 Fast Set flange fasten down, and does it work on both wood and concrete floors?
There are 4 screw holes plus 4 mounting slots, which Oatey provides so the flange can be anchored on any installation type. The slots let you shift the bolt position to line the closet bolts up with the bowl. Fasteners are not part of the fitting, so pick them for your substrate: wood screws for a subfloor, concrete anchors for a slab.
3) Is the Oatey 43621 toilet flange code listed for a permitted plumbing job?
It carries a UPC listing and meets ASTM D2665, the standard for PVC DWV pipe and fittings. That's what an inspector looks for on a residential or commercial closet flange in a UPC jurisdiction.
4) Is the Oatey 43621 flange a metal ring or plastic ring?
Plastic. The 43621 has an integrated plastic ring rather than a stainless or cast iron ring. It's a one-piece white PVC body, so there's nothing to corrode in a wet bathroom floor, but it also means you're relying on the plastic for the closet bolt bearing surface. If your spec calls for a metal ring, this isn't the version to order.
5) Does this Oatey offset flange sit on top of the finished floor or recessed into it?
It sits flush on the floor. The flange is designed to rest on top of the finished floor surface, which is what you want under a standard wax ring. If your pipe is cut too low and the flange ends up below the finish floor, you'll need an extension ring and a longer set of closet bolts to make up the difference.
6) Should I use an offset closet flange or a standard straight one?
Use a straight flange when the drain stub-out is already centered where the toilet will sit. Reach for the offset 43621 when it isn't, which is typical on remodels, wall relocations, or a rough-in that came in short. Bear in mind an offset restricts the effective opening compared to a concentric flange, so don't use one where a straight flange would have worked.
7) What do I need to order along with the Oatey 43621 flange to finish the toilet set?
The flange itself is the fitting only. Plan on PVC primer and solvent cement for the 4 in. joint, floor fasteners suited to your subfloor, a pair of closet bolts, and a wax ring or waxless seal. For a property manager stocking a truck, those are the four items that turn this into a completed toilet installation.
8) What is the exact Oatey part number for this Fast Set offset flange with the plastic ring?
Order it as Oatey 43621-FASTSET. It's the Fast Set offset closet flange, white PVC, 4 in., solvent weld with an integrated plastic ring.
