It connects hub to spigot ends, allowing a smooth transition between no-hub cast iron pipe and PVC DWV pipe in the same drainage run. The fitting is manufactured in white PVC for lightweight handling and corrosion resistance. Licensed plumbers and pipefitters install this type of adapter when joining dissimilar materials or extending an existing DWV stack. It is a straightforward, single-piece fitting with no gaskets or fasteners required beyond standard solvent cement on the hub end.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and light commercial DWV applications where a 4-inch nominal pipe size is required. Typical installations include drain stack tie-ins, horizontal branch connections, and transitions from underground cast iron mains to above-grade PVC runs. The hub end accepts solvent-welded PVC pipe, while the spigot end inserts into a no-hub coupling with a stainless steel band clamp. Plumbers working on new construction, renovation, or repair projects will find this fitting useful wherever a DWV pipe-to-no-hub transition is needed at the 4-inch size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch nominal pipe size fits standard DWV drain, waste, and vent lines\u003c\/li\u003e\n  \u003cli\u003eHub x Spigot end configuration for solvent-cement-to-no-hub coupling transitions\u003c\/li\u003e\n  \u003cli\u003eWhite PVC construction provides corrosion resistance and low weight\u003c\/li\u003e\n  \u003cli\u003eDWV-rated fitting intended for gravity-flow drainage applications\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design with no internal components to fail or replace\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard installation fitting for 4-inch residential and commercial PVC DWV piping systems requiring a hub-to-spigot no-hub transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the drain line is clear before cutting into an existing system. Use the appropriate PVC primer and solvent cement on the hub end per manufacturer and code requirements. The spigot end requires a no-hub stainless steel band coupling torqued to the coupling manufacturer specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hub x Spigot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDWV Rated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40171708\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: WESTLAKE PIPE FITTINGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dwv-d119-040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Westlake Pipe \u0026 Fittings","offers":[{"title":"Default Title","offer_id":51138877161778,"sku":"DWV-D119-040","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532687.jpg?v=1778265156","url":"https:\/\/voomisupply.com\/products\/westlake-pipe-fittings-dwv-d119-040-dwv-no-hub-adapter-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
