3 inch PVC Open Closet Toilet with Stainless Steel Swivel Ring Total Knockout

3" PVC Closet Flange with Stainless Steel Ring – Fixed Ring, Spigot Connection for Gravity DWV Systems

This 3" closet flange is constructed from Schedule 40 PVC and features a corrosion-resistant stainless steel ring for secure toilet mounting in drainage applications. The flange body is designed with a spigot outlet that fits directly into a 3" PVC hub fitting, offering a solvent-weld connection compatible with standard DWV system layouts.

The fixed-position stainless steel ring is mechanically fastened to the flange body and includes elongated slots to accommodate closet bolts. This design allows for secure anchoring of the toilet base to the floor while maintaining alignment under load and minimizing deflection over time.

Technical Specifications

• Nominal Size: 3 inches
• Flange Body Material: PVC (conforming to ASTM D2665)
• Ring Material: Type 430 stainless steel, fixed rotation
• Outlet Type: Spigot – fits into 3" hub
• Mounting Features: Four or more closet bolt slots, predrilled screw holes for floor attachment
• Certifications: UPC listed; complies with IPC, UPC, and ASTM standards

Typical Applications

• Toilet rough-in connections in residential and light commercial construction
• New construction or replacement scenarios where spigot outlet is preferred
• Installations requiring durable floor-mounted toilet anchors within DWV systems

Installation Considerations

The flange is installed by solvent-welding the spigot outlet into a 3" PVC hub fitting using primer and cement rated for Schedule 40 DWV systems. The stainless ring should be mechanically fastened to the finished floor using corrosion-resistant screws. Ensure that the flange is level and installed flush with the finished flooring surface to maintain code compliance and fixture alignment.

Material Advantages

PVC body construction offers resistance to corrosion and scale buildup while reducing installation weight compared to cast iron alternatives. The fixed-position stainless steel ring improves long-term structural performance and corrosion resistance in moisture-prone environments.

Summary

The 3" PVC closet flange with stainless steel ring is designed for code-compliant toilet installations in gravity drainage systems. Its spigot connection, durable materials, and secure mounting configuration make it a reliable solution for both new construction and replacement applications in residential and commercial plumbing systems.
