It features a male NPT (MNPT) end connection that threads directly into a female-threaded fitting or pipe opening. The ABS construction handles a working temperature range of -40 degrees F to 180 degrees F, making it suited for standard residential and light commercial DWV applications. Plumbers and pipefitters install this plug as part of ABS DWV system assemblies.\u003c\/p\u003e\u003cp\u003eThis plug is used in residential and light commercial drain, waste, and vent piping systems constructed with ABS pipe and fittings. Common applications include capping open test ports after DWV pressure or smoke testing, sealing off stub-outs on unused fixture connections, and closing branch lines during phased construction. The 1-1\/4 inch size fits branch lines typically serving lavatories, utility sinks, and similar fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch MNPT connection threads into standard female NPT DWV fittings\u003c\/li\u003e\n\u003cli\u003eABS construction rated from -40 degrees F to 180 degrees F\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.03 pounds, minimizing added load on branch lines\u003c\/li\u003e\n\u003cli\u003eISO 9001:2008 manufactured under a certified quality management system\u003c\/li\u003e\n\u003cli\u003eSingle-piece plug design with no moving parts for reliable sealing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for ABS DWV piping systems using 1-1\/4 inch female NPT threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers in accordance with applicable plumbing codes such as the IPC or UPC. Shut off water supply and verify the line is depressurized before installing or removing any DWV plug. Hand-tighten first, then use a strap wrench or pipe wrench for final snugging — do not overtighten ABS threaded fittings, as the material can crack under excessive torque. Confirm thread engagement is complete before conducting any line pressure or smoke test.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: MIPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Acrylonitrile Butadiene Styrene (ABS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: I177150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51540512244018,"sku":"I177150","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d14b4bda50ad3a3721ed8a4f4f716808.jpg?v=1785857033","url":"https:\/\/voomisupply.com\/products\/nibco-i177150-dwv-plug-1-1-4-inch-mnpt-abs","provider":"Voomi Supply","version":"1.0","type":"link"}
