Wrot copper fittings are wrought from copper alloy, producing a denser, stronger fitting than cast alternatives. This coupling is used to extend or repair DWV piping runs and is installed by licensed plumbers working on residential or light commercial drain and vent systems. The sweat-solder end connections create a reliable, leak-resistant joint when properly fluxed and soldered.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for horizontal and vertical DWV piping runs inside residential and light commercial construction. It is a direct-connect fitting used when extending drain lines, repairing damaged sections of copper DWV pipe, or tying into existing 1-1\/2 inch copper waste or vent stacks. Plumbers working on bathroom sink drains, laundry standpipes, and vent risers will commonly encounter this fitting size. It is not rated for pressure supply service and is intended exclusively for gravity-flow DWV applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWrot copper construction for consistent wall thickness and high joint integrity\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch C x C end connections accept standard DWV copper tubing\u003c\/li\u003e\n\u003cli\u003eSweat-solder joints compatible with standard lead-free solder and flux\u003c\/li\u003e\n\u003cli\u003eDesigned for gravity-flow DWV service, not pressure water supply\u003c\/li\u003e\n\u003cli\u003eCompact coupling profile suited for tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 1-1\/2 inch copper DWV piping systems using cup-by-cup sweat connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and drain any connected piping before cutting into an existing DWV system. Clean and flux both the pipe ends and the fitting cups thoroughly before applying heat and lead-free solder. Do not use this fitting on pressurized water supply lines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Cup x Cup (C x C) sweat solder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Wrot copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Type\u003c\/strong\u003e: DWV (drain, waste, vent) gravity flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DWVCOUP112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524697719090,"sku":"DWVCOUP112","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81a7f280aa44581a005d8f6e831f3b05_52e3b1ba-7d99-4c99-aa9f-4d1ede21781d.jpg?v=1785455620","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-dwvcoup112-dwv-coupling-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
