This fitting is engineered for gravity-fed, non-pressure waste elimination systems and is rated for service up to 140 degrees F. Made from lightweight PVC, it simplifies handling and positioning during installation without sacrificing durability. Licensed plumbers and pipefitters install this fitting in residential and commercial DWV systems where a pipe diameter change is needed inline. Solvent cement joining keeps the process straightforward and eliminates the need for specialty tooling.\u003c\/p\u003e\n\u003cp\u003eThis reducer coupling is used wherever a DWV system requires a step-up or step-down transition between 4-inch and 8-inch PVC pipe runs. Typical applications include main drain stacks, building drain transitions, and vent stack connections in both residential and light commercial construction. The fitting is compatible with standard PVC DWV pipe and accepts solvent cementing, threading, flanging, and roll-grooved joining methods, giving installers flexibility based on site conditions and local code requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions between 4-inch and 8-inch PVC DWV pipe in a single fitting\u003c\/li\u003e\n  \u003cli\u003eRated for non-pressure gravity-fed drain, waste, and vent systems\u003c\/li\u003e\n  \u003cli\u003eMaximum service temperature of 140 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompatible with solvent cement, threaded, flanged, and roll-grooved joining methods\u003c\/li\u003e\n  \u003cli\u003eLightweight PVC construction requires no special cutting tools\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for standard 4-inch and 8-inch PVC DWV piping systems used in residential and commercial drain, waste, and vent applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the pipe run is fully drained before cutting into an existing system. When solvent cementing, use a PVC-rated primer and cement appropriate for the pipe schedule and follow the manufacturer's cure time before restoring flow. Cutting can be performed with a hand saw or power saw without specialty tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size (Inlet)\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size (Outlet)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Type\u003c\/strong\u003e: DWV (Drain, Waste, Vent) — Non-Pressure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJoining Methods\u003c\/strong\u003e: Solvent cement, threaded, flanged, roll-grooved\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 611942113439\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHARLOTTE PIPE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PVC-102-4X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHARLOTTE PIPE","offers":[{"title":"Default Title","offer_id":51383559029042,"sku":"PVC-102-4X8","price":70.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671588.png?v=1782600497","url":"https:\/\/voomisupply.com\/products\/charlotte-pipe-pvc-102-4x8-pvc-dwv-reducer-coupling-4x8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
