Sioux Chief 884-PTM PVC Closet Flange with Test Knockout and Stainless Steel Swivel Ring, 3" x 4"

The Sioux Chief 884-PTM is a PVC closet flange built for behind-the-wall and under-floor toilet rough-in work, featuring a 3" hub that accepts 4" DWV pipe and a Test Knockout (TKO) that lets plumbers pressure- or water-test the drain line before the fixture is ever set. A stainless steel swivel ring rotates independently of the flange body so the closet bolt slots can be squared to the toilet base even if the flange itself lands slightly out of alignment during rough-in. Molded from PVC for corrosion resistance in wet, below-slab, and crawlspace conditions, this flange is designed to be solvent-welded or fitted into the drain stub-out and set flush to the finished floor so the toilet sits level and properly sealed once the flooring is down.

Key Features

  • Trade Size: 3" hub connects to 4" DWV pipe for standard toilet drain rough-in.
  • Durable PVC Construction: Molded PVC body resists corrosion and is well suited to below-grade, slab, and wet rough-in conditions.
  • Test Knockout (TKO): Removable knockout section keeps the drain line sealed for pressure- or water-testing before the flange is permanently set, then knocks out cleanly for final installation.
  • Stainless Steel Swivel Ring: Rotating ring lets closet bolt slots be aligned independently of the flange body for accurate toilet setting, even on a rotated or offset rough-in.
  • Hub-Style Connection: Hub end is sized to fit directly over 4" DWV pipe for a straightforward rough-in tie-in without extra adapters.
  • Flush-Set Design: Flange sets flush to the finished floor for a stable, level base under the toilet flange bolts.

Technical Specifications

  • Trade Size: 3" Hub x 4" Pipe
  • Material: PVC body with stainless steel swivel ring
  • Country of Origin: United States
  • Packaging: 24 EA per carton

Sioux Chief 884-PTM – Frequently Asked Questions

1) Will the Sioux Chief 884-PTM closet flange fit 4 inch DWV pipe or 3 inch?
The 884-PTM is a 3 inch hub x 4 inch pipe flange: the hub end slips over 4 inch DWV pipe directly, with no bushing or adapter. If your toilet stub-out is 3 inch pipe, this is not the right fitting for it, you'd want a flange sized to fit inside or over 3 inch pipe instead.
2) What does the TKO on the 884-PTM closet flange actually do on the job?
TKO stands for Test Knockout. The flange ships with a removable knockout section closing off the drain, so you can water- or pressure-test the DWV line during rough-in before any fixture is set. Once the test passes and you're ready to set the toilet, the knockout breaks out cleanly and the flange is ready for the wax ring and closet bolts. If your inspector doesn't require a line test, a plain flange without the knockout does the same job.
3) My toilet drain rough-in came in slightly rotated. Can I still get the closet bolts square with the 884-PTM?
That is what the stainless steel swivel ring is for. The ring carries the closet bolt slots and rotates independently of the PVC flange body, so you can square the bolts to the toilet base even when the flange itself landed off-angle in the rough-in. It saves cutting the pipe back and resetting the fitting.
4) Can a PVC closet flange like the Sioux Chief 884-PTM be used under a slab or in a crawlspace?
Yes. The body is molded PVC, which resists corrosion in wet, below-slab, and crawlspace rough-in, and the swivel ring is stainless steel. It's used on slab-on-grade and wood-frame floor rough-ins alike. For a cast iron or steel drain system you'd be looking at a different flange material, but for PVC or ABS DWV work under a floor this is the standard approach.
5) How high should the 884-PTM flange sit relative to the finished floor?
Set it flush to the finished floor, not to the subfloor. The flange is designed to sit level on top of the finished surface so the toilet base seats flat and the wax seal compresses evenly. If you're tiling, account for tile and thinset thickness before you solvent-weld the flange in place.
6) How is the 884-PTM closet flange connected to the drain line?
It's a hub-style connection, solvent-welded onto the 4 inch DWV stub-out. No gaskets or mechanical couplings, just primer and PVC cement. The hub slips over the pipe rather than inside it, so the pipe end needs to be cut square and clean.
7) Does the Sioux Chief 884-PTM come with closet bolts and a wax ring?
The 884-PTM is the flange and its stainless steel swivel ring. Closet bolts, the wax or foam seal, and the floor fasteners are separate items you'll need on the truck to finish setting the toilet. Solvent cement and primer for the hub joint are also separate.
8) How many Sioux Chief 884-PTM flanges come in a carton for a multi-unit job?
Cartons are 24 each, which is a practical stocking quantity for crews roughing in toilets across multiple units. The 884-PTM is made in the United States.
