Manufactured to ASTM D2665, F1498, D331, and D1784 standards and certified to NSF 14, this fitting delivers smooth, consistent interior walls that promote full flow and resist scaling and corrosion. It is installed by licensed plumbers in residential and light commercial drainage systems where a transition between 6-inch and 4-inch hub-end pipe is required.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for non-pressurized DWV applications in sanitary drain, waste, and vent piping systems. The hub-by-hub configuration accepts solvent-welded PVC pipe on both ends. Typical installation scenarios include main drain stack reductions, building drain transitions, and branch connections where pipe diameter changes are necessary. The fitting is appropriate for use in residential new construction, renovation work, and commercial plumbing projects governed by applicable plumbing codes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch by 4-inch increaser\/reducer with hub-by-hub solvent-weld connections\u003c\/li\u003e\n  \u003cli\u003eSmooth interior walls promote full flow and reduce scaling buildup\u003c\/li\u003e\n  \u003cli\u003eSuperior resistance to chemicals and corrosion inherent to PVC material\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASTM D2665, F1498, D331, and D1784 specifications\u003c\/li\u003e\n  \u003cli\u003eNSF 14 certified for drain, waste, and vent applications\u003c\/li\u003e\n  \u003cli\u003eUniform interior and exterior dimensions for consistent, reliable fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style DWV replacement or new-installation fitting for non-pressurized PVC sanitary drain, waste, and vent piping systems using hub-end connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local authority having jurisdiction.
