Sioux Chief 886-GI Cast Iron Closet Flange with Push-Tite Inside Outlet, 4"

The Sioux Chief 886-GI is a 4" cast iron closet flange built with a Push-Tite inside outlet designed to seal directly inside DWV pipe. Rather than requiring a hub connection, this flange pushes into the existing drain pipe and fastens directly to the floor, making it a straightforward option for both new rough-in work and replacement jobs where a damaged or outdated flange needs to come out. The cast iron body gives installers a rigid, durable base for the closet bolts and wax ring that will carry the toilet above, and the design keeps the waterway open and unobstructed through the transition from pipe to fixture.

Key Features

  • Trade Size: 4" inside outlet sized to seal directly inside 4" DWV pipe.
  • Durable Construction: Cast iron body provides a rigid, long-wearing flange that stands up to the stress of floor mounting and closet bolt loading.
  • Push-Tite Connection: The gasket seals inside the DWV pipe for easy installation - simply push the flange into the pipe and fasten it to the floor, with no solvent welding or hub cutting required.
  • Smooth Flow Channel: A large flow channel with smooth inner walls and no internal obstructions or ledges helps reduce the chance of waste buildup and clogs at the transition point.
  • Replacement-Friendly Design: Works equally well for new construction or as a drop-in replacement flange when an existing fitting has failed or corroded.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing parts around practical jobsite installation, and the 886-GI closet flange reflects that approach with its push-in Push-Tite connection and cast iron construction. The smooth, obstruction-free flow channel and straightforward push-and-fasten installation make it a dependable choice for plumbers handling both new installs and flange replacements on existing DWV lines.

Sioux Chief 886-GI – Frequently Asked Questions

1) Will the Sioux Chief 886-GI closet flange fit inside 4 inch DWV pipe, or does it need a hub?
The 886-GI seals inside 4 inch DWV pipe. It is an inside-outlet flange with a Push-Tite gasket, so you push it down into the existing 4 inch drain and fasten the ring to the floor. No hub connection, no solvent welding, no cutting a hub off the stack. If your rough-in terminates with a hub you need to set a flange over, this is the wrong style.
2) Can I use a push-in toilet flange to replace a corroded old flange without cutting the pipe?
That is exactly what the 886-GI is built for. Because it seals inside the pipe rather than over a hub, you remove the failed fitting, push the new flange into the remaining 4 inch DWV line, and bolt it down to the floor. It works the same way on new rough-in as it does on a replacement.
3) Is a cast iron closet flange better than plastic for a commercial restroom?
The 886-GI uses a cast iron body, which gives a rigid base under the closet bolts and wax ring. In high-traffic commercial restrooms where toilets get rocked and re-set repeatedly, that rigidity is the reason specifiers pick iron over a plastic ring. The tradeoff is weight and the fact that iron is the heavier part to handle in a tight joist bay.
4) Do I still need a wax ring and closet bolts with this flange?
Yes. The 886-GI is the floor flange only. The toilet is sealed to it with a wax ring and held down by closet bolts seated in the flange slots, so both are part of the job and are bought separately. The Push-Tite gasket on the outlet handles only the seal between the flange and the DWV pipe.
5) Does the 886-GI flange restrict flow where the toilet meets the drain?
No. The flow channel through the 886-GI is full and open, with smooth inner walls and no internal ledges or obstructions at the pipe-to-fixture transition, which is where waste tends to catch on flanges that neck down.
6) How many Sioux Chief 886-GI flanges come in a box?
The 886-GI is packaged 5 each. Worth knowing if you are buying for a single bathroom remodel versus a multi-unit rough-in where five flanges get used in a day.
