Manufactured from cast iron with a galvanized finish, it features a male NPT (MNPT) end style sized at 3 inches nominal. The 125 lb pressure class rating makes it suitable for standard-service pipework. Licensed plumbers and pipefitters install this fitting during system assembly, pressure testing, or temporary line isolation. The galvanized coating provides corrosion resistance in exposed or damp environments.\u003c\/p\u003e\n\u003cp\u003eThis square head plug is used in residential and commercial plumbing, HVAC hydronic systems, and industrial piping where a reliable threaded pipe termination is required. The cored design distinguishes it from a solid plug, allowing for future tapping or line extension if needed. It is a domestically manufactured fitting appropriate for above-ground and in-wall applications on threaded cast iron or steel pipe systems rated at 125 lb service class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 inch nominal MNPT end style for standard threaded pipe connections\u003c\/li\u003e\n  \u003cli\u003eCast iron construction rated for 125 lb service class\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in damp or exposed environments\u003c\/li\u003e\n  \u003cli\u003eCored design allows for future tapping without full fitting replacement\u003c\/li\u003e\n  \u003cli\u003eSquare head drive provides positive wrench engagement during installation\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured fitting\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 3 inch nominal threaded cast iron and steel pipe systems operating at 125 lb service class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters using a pipe wrench sized for the square head drive. Always depressurize and isolate the pipe section before removing or installing threaded plugs. Apply an appropriate thread sealant or PTFE tape to the MNPT threads in accordance with local plumbing code requirements. Do not overtighten cast iron fittings, as the material is brittle and susceptible to cracking under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3 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 Class\u003c\/strong\u003e: 125 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Square Head, Cored Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic (USA)\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: ASC Engineered Solutions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3.NP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51524702011698,"sku":"GALPL3","price":56.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a16ac84ab8df35dea0d7b8d95aac5487_c93cb6aa-03bb-4c1b-a81c-9630dca65d9e.jpg?v=1785455767","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-3-np-square-head-plug-3-inch-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
