The plug features a male NPT (MNPT) end style and a 1-1\/4 inch nominal size, making it a standard-dimension fitting for threaded pipe assemblies. Rated at 125 lb, this brass plug is supplied with a rough finish and is an import product. Plumbers and pipefitters install this type of fitting to cap or plug threaded ports in pipe networks, manifolds, and valve bodies.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial plumbing, hydronic heating systems, and general-purpose piping applications where a brass, threaded square head plug is specified. The square head profile allows for easy wrench engagement during installation and removal. At 1-1\/4 inch MNPT, it fits standard Schedule 40 threaded pipe fittings and valve bodies of the same nominal size. The 125 lb pressure class is appropriate for low-pressure water and air service typical in these applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch nominal MNPT thread for compatibility with standard threaded pipe systems\u003c\/li\u003e\n  \u003cli\u003e125 lb pressure class rating suitable for low-pressure water and air service\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in water and air piping\u003c\/li\u003e\n  \u003cli\u003eCored square head design allows positive wrench grip for installation and removal\u003c\/li\u003e\n  \u003cli\u003eRough finish suitable for use as-is or with thread sealant tape or compound\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 1-1\/4 inch MNPT threaded pipe systems rated at 125 lb class pressure service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC or local plumbing code requirements. Shut off system pressure and drain the line before installing or removing any threaded plug. Apply an appropriate thread sealant compound or PTFE tape to the male threads before engagement to ensure a leak-free seal. Use a proper box or open-end wrench on the square head — do not use pipe wrenches on the head itself, as this can damage the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: MNPT (Male National Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 125 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Rough\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Cored Square Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Import\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XNL117-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51524946493746,"sku":"PLUG114LF","price":19.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a86a50b22faff591a258f200343443d_b3033c7a-2f57-4f4d-94ee-32e1efa78eb1.jpg?v=1785462081","url":"https:\/\/voomisupply.com\/products\/merit-brass-xnl117-20-cored-square-head-plug-1-1-4-in-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
