The square head drive style allows for positive wrench engagement during installation and removal, making it a reliable choice for pressure-tested systems and service applications. Constructed from malleable iron with a galvanized finish, this plug resists corrosion in typical plumbing and mechanical environments. At 2 inches nominal size, it fits standard NPT threaded connections and is commonly installed by licensed plumbers and pipefitters working on commercial and industrial piping systems.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for use in water, air, and low-pressure gas piping systems where a threaded pipe end must be temporarily or permanently sealed. The galvanized malleable iron construction makes it appropriate for exposed or mildly corrosive environments. Typical applications include plumbing rough-ins, mechanical room piping, fire protection system drain points, and hydronic heating system capping. It is an import product intended for general trade use where an OEM-spec fitting is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2 inch nominal NPT threaded fitting for standard pipe compatibility\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and resistance to impact during installation\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish adds corrosion resistance for plumbing and mechanical service environments\u003c\/li\u003e\n  \u003cli\u003eCored square head design enables secure wrench engagement for proper torque application\u003c\/li\u003e\n  \u003cli\u003eSuitable for permanent or service-access pipe end closures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard trade fitting for 2 inch NPT threaded piping systems in plumbing, mechanical, and light industrial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing codes. Depressurize and drain the piping system before removing or installing threaded plugs. Apply appropriate thread sealant or PTFE tape to the male threads before installation. Use a properly sized wrench on the square head to avoid rounding the drive surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable 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: Cored Square Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\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: SIGMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 819902578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524353655090,"sku":"GALPL2I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7fa60f85911efd2327b7d52f8ddca0b_fe71905a-2cdf-42b1-9bfd-2542e7dd1386.jpg?v=1785446798","url":"https:\/\/voomisupply.com\/products\/sigma-819902578-cored-square-head-plug-2-inch-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
