Professional Specifications

The EZ-FLO 40054 DWV Closet Flange Extension is fabricated from schedule-grade PVC resin formulated for rigidity and resistance to impact, corrosion, and chemical degradation. The 3 x 4 inch connection configuration accommodates multiple DWV pipe sizes, providing installation flexibility for new construction or retrofit applications. The flange maintains a uniform 3/8-inch thickness for consistent elevation and alignment of the toilet base flange with finished floor surfaces. The solvent-weld connection ensures a permanent, leak-free joint, while the PVC material withstands exposure to standard wastewater environments. This fitting meets dimensional and structural performance requirements defined by ASTM standards for DWV applications.
