Sioux Chief 886-4PM 4 Inch Hub Pvc Closet Flange

Product Description

The Sioux Chief 886-4PM is a 4-inch hub-style PVC closet flange designed for Schedule 40 DWV (drain, waste, and vent) systems. It connects a toilet to the drain line at floor level, creating a secure, leak-resistant seal between the toilet horn and the drain stack. Built from Schedule 40 PVC, this flange provides durable, corrosion-resistant performance in residential and light commercial plumbing applications. Licensed plumbers install this component during new construction rough-in or as a replacement flange in remodel and repair work where the existing flange is cracked, broken, or corroded.

This closet flange is suited for residential toilet installations and light commercial bathroom rough-in work. The hub-style connection solvent-welds directly onto a 4-inch PVC DWV pipe, making it a straightforward fit for standard drain configurations. It is commonly used in new construction, bathroom remodels, and repair scenarios where the waste line terminates with a 4-inch Schedule 40 PVC stub-out. This part is sold individually as a single unit.

Compatibility

Designed as an OEM-style replacement and new-construction component for 4-inch Schedule 40 PVC DWV drain systems in residential and light commercial toilet installations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and clear the drain line before beginning work. Solvent-weld the hub connection using PVC primer and cement rated for DWV applications, following the cement manufacturer's cure time before applying load or making the toilet connection. Ensure the flange ring sits flush with or slightly above the finished floor surface to allow a proper wax ring seal.
