It features two hub ends that accept standard 4-inch PVC pipe, creating a solvent-weld joint suitable for DWV service. This fitting is manufactured to Schedule 40 dimensional standards and is intended for use in gravity-flow drainage applications. Licensed plumbers and pipefitters install this coupling during repairs or new construction where a full-length coupling without an internal stop is required to slide over existing pipe ends.\u003c\/p\u003e\n\u003cp\u003eThis repair coupling is used in residential and light commercial DWV systems where standard 4-inch PVC drain pipe is present. Its hub-end configuration makes it well suited for in-line pipe repairs where access is limited and a slip-style coupling is needed to join two pipe ends without cutting back to a fitting stop. It is appropriate for horizontal drain lines, vertical stacks, and vent piping that operate under gravity flow rather than pressure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch nominal pipe size fits standard Schedule 40 PVC DWV pipe\u003c\/li\u003e\n  \u003cli\u003eHub ends on both sides accept solvent-weld connections\u003c\/li\u003e\n  \u003cli\u003eSchedule 40 wall thickness meets standard DWV dimensional requirements\u003c\/li\u003e\n  \u003cli\u003ePVC construction resists corrosion and chemical degradation common in drain service\u003c\/li\u003e\n  \u003cli\u003eRepair coupling design allows installation over existing pipe ends without a stop\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting compatible with 4-inch Schedule 40 PVC DWV piping systems 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 a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments. Shut off water flow and ensure the pipe section is dry before solvent-welding. Clean and prime both the pipe ends and the hub sockets with the appropriate PVC primer before applying PVC solvent cement. Allow full cure time per the cement manufacturer's instructions before restoring flow.\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\u003eSchedule\u003c\/strong\u003e: 40\/STD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hub x Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: DWV (Drain, Waste, Vent)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40172608\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-d130-040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Westlake Pipe \u0026 Fittings","offers":[{"title":"Default Title","offer_id":51138812870962,"sku":"DWV-D130-040","price":25.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532682.webp?v=1778263846","url":"https:\/\/voomisupply.com\/products\/westlake-pipe-fittings-dwv-d130-040-dwv-repair-coupling-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
