Sioux Chief 888-PM PVC Closet Flange, Swivel Ring

Sioux Chief 888-PM PVC Closet Flange, Swivel Ring

The Sioux Chief 888-PM is a PVC closet flange built for toilet rough-in and replacement work, available in 3" and 4" sizes to match standard DWV drain piping. Every flange in the 888-PM family features a stainless steel swivel ring and an extended outlet for a secure connection to the drain line, joined with a solvent-weld connection for a permanent, leak-resistant joint. The PVC body resists corrosion in drain, waste and vent (DWV) applications, while the swivel ring rotates freely so installers can square the closet bolt slots to the finished floor without twisting the pipe joint below the slab or subfloor. Manufactured in the United States, this flange family is sized for standard 3" and 4" DWV piping in both residential and commercial rough-in work.

Key Features

• Trade Size: Available in 3" and 4" to match standard closet-flange rough-in connections on 3" and 4" DWV piping.
• PVC Construction: Solvent-weld PVC flange body resists corrosion and holds up to everyday DWV service conditions behind the wall or under the floor.
• Stainless Steel Swivel Ring: The swivel ring turns independently of the flange body, letting installers square the closet bolt slots to the finished floor without disturbing the pipe joint underneath.
• Extended Outlet: An extended outlet spigot gives installers extra reach into the drain fitting, useful where subfloor thickness or fitting depth varies on the job.
• Solvent Weld Connection: The flange outlet is built for a solvent-weld joint to the drain fitting, providing a permanent, leak-resistant connection at the rough-in.
• Closet Bolt Slots: Slotted flange face accepts standard closet bolts for a secure toilet-to-floor connection.
• Country of Origin: Manufactured in the United States for consistent fit and quality control across both sizes.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing components to stand up to the demands of daily trade use, and the 888-PM closet flange family is no exception. The PVC body and stainless steel swivel ring are engineered to give installers a corrosion-resistant, properly aligned connection at the toilet rough-in in either the 3" or 4" size, helping reduce callbacks tied to loose or misaligned closet bolts. The extended outlet design and solvent-weld connection give extra working room and a dependable joint on jobs where fitting depth or subfloor thickness is inconsistent, so crews spend less time fabricating workarounds in the field. For plumbers and contractors who need a dependable, domestically manufactured flange for new construction or replacement work, the 888-PM delivers consistent fit at the rough-in stage, in whichever size the job calls for.
