4 inch x 3 inch PVC DWV Slip Toilet Flange with Metal Ring Adjustable

PVC DWV Closet Flange with Metal Ring – Slip Fit for Secure Toilet Installations

The PVC Closet Flange DWV Slip with Metal Ring is a durable, code-compliant fitting designed to provide a secure connection between the drainage waste-vent (DWV) system and floor-mounted water closets. The flange incorporates a corrosion-resistant metal ring mechanically bonded to a PVC body, supporting both long-term performance and structural stability during installation and operation.

With a slip-style hub designed to fit over 3" or inside 4" DWV pipe, this flange simplifies the alignment and setting of the toilet fixture while providing a reliable anchor for closet bolts. It is engineered to meet dimensional and performance requirements of standard residential plumbing installations involving gravity drainage systems.

Key Features and Functional Advantages

• ✅ Reinforced Ring Design: Integrated metal ring enhances bolt-holding strength and resists flange deformation under load.
• ✅ PVC Body Construction: Non-corrosive thermoplastic suitable for contact with soil and waste in horizontal drainage applications.
• ✅ Slip-Fit Hub: Allows direct solvent-weld to 3" or 4" DWV pipe without the need for specialty fittings or adapters.
• ✅ Code-Conforming Dimensions: Manufactured in compliance with applicable plumbing standards for residential systems.
• ✅ Load Bearing Stability: Maintains joint integrity during fixture movement and under weight-bearing loads.

Technical Specifications

• Material: PVC (body) with galvanized or stainless steel ring
• Size: 4" x 3" (slip over 3", inside 4" pipe)
• Connection Type: Slip hub, solvent-weld installation
• Configuration: DWV system component; designed for closet flange applications
• Compliance: Typically conforms to ASTM D2665 and ASME A112.4.3 performance criteria

Installation Notes

Ensure pipe is clean and dry prior to solvent-welding. Dry-fit the flange to verify alignment with toilet bolt slots positioned parallel to the back wall. After solvent cement is applied and the flange is set, anchor the ring to the subfloor using corrosion-resistant fasteners. The flange must be flush with or above finished floor height for optimal seal with the wax ring or gasket.

Typical Use Cases

This type of flange is used in residential DWV systems, typically at floor level in bathroom installations. It serves as the connection point for water closets in new construction, remodels, and service replacements. Its robust metal ring offers added support in subfloor installations over wood, concrete, or tile substrates.

Technical Insight

The addition of a metal ring to a PVC closet flange increases tensile strength and provides a stable base for closet bolts, reducing the potential for movement or failure over time due to fixture shifting, thermal expansion, or installation stress.

The PVC Closet Flange DWV Slip with Metal Ring is a critical component in gravity waste systems, offering mechanical stability and dimensional compatibility with standard DWV piping in code-compliant installations.
