It connects a 4-inch closet flange to a 3-inch drain line, providing the necessary transition at the base of a toilet installation. Licensed plumbers install this fitting during new construction and remodel work where the floor drain stub-out does not match the full 4-inch flange diameter. The ABS material is lightweight, chemically resistant, and compatible with standard ABS solvent-cement joining methods.\u003c\/p\u003e\u003cp\u003eThis reducing closet flange hub is used in residential and light commercial plumbing applications. It is suited for installations where an existing 3-inch ABS DWV drain line needs to support a standard toilet flange connection. The fitting is typically set into or mounted over the floor, allowing the toilet horn to seat and seal properly. Plumbers use it in slab-on-grade and wood-frame floor assemblies where reducing the drain outlet size is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReduces from 4-inch flange to 3-inch hub connection for flexible drain line sizing\u003c\/li\u003e\n\u003cli\u003eABS plastic construction — lightweight and resistant to common drain chemicals\u003c\/li\u003e\n\u003cli\u003eHub-style inlet accepts standard 3-inch ABS pipe with solvent cement\u003c\/li\u003e\n\u003cli\u003eDesigned for DWV systems — not rated for pressure applications\u003c\/li\u003e\n\u003cli\u003eCompatible with standard ABS solvent-cement installation methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential and light commercial ABS DWV drain systems requiring a 4-inch x 3-inch reducing closet flange connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed plumber in accordance with local plumbing codes and the IPC or applicable state code.
