Square head plugs are used to close off threaded pipe openings in piping systems while allowing removal with standard wrenches when access is needed later. The galvanized coating provides corrosion resistance for use in wet or mildly corrosive environments. This fitting is a standard component in plumbing, mechanical, and industrial piping work installed by licensed plumbers and pipefitters.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for residential and commercial piping systems where a threaded pipe end must be sealed temporarily or permanently. The cored design and square head allow easy engagement with a wrench for installation and future removal. Typical applications include capping branch tees, plugging unused outlets on valves or manifolds, and closing test ports in piping assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch nominal thread size fits standard NPT threaded pipe and fittings\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and resistance to mechanical stress\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish adds corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eSquare head design allows engagement with a standard open-end or adjustable wrench\u003c\/li\u003e\n  \u003cli\u003eCored plug design reduces material weight while maintaining thread integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard stock fitting for use with 1\/2 inch NPT threaded piping systems in plumbing and mechanical applications.\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 mechanical code requirements. Shut off and depressurize the piping system before installing or removing any threaded plug. Apply appropriate thread sealant or PTFE tape to the male threads before installation. Do not over-tighten malleable iron fittings, as the material can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Thread Size\u003c\/strong\u003e: 1\/2 inch\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: Square Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlug Type\u003c\/strong\u003e: Cored\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: 819901810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524629299506,"sku":"GALPL12I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7fa60f85911efd2327b7d52f8ddca0b_434a5154-a388-436f-8032-d34444022d1e.jpg?v=1785453487","url":"https:\/\/voomisupply.com\/products\/sigma-819901810-cored-square-head-plug-1-2-in-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
