Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting handles a broad range of residential and light commercial applications. The 3\/8 inch fitting size accepts standard NPT threading, and a galvanized finish provides corrosion resistance in damp or exposed environments. Licensed plumbers and pipefitters install this type of plug during system testing, winterization, or any time an open pipe end must be capped off cleanly and securely.\u003c\/p\u003e\n\u003cp\u003eThis square plug is suited for use in gas lines, water supply systems, steam distribution, and HVAC hydronic piping wherever a 3\/8 inch threaded port needs to be closed. The square head design allows for easy wrench engagement during installation and removal. Typical scenarios include capping unused branch outlets, pressure testing isolated pipe sections, and sealing off decommissioned connections. This fitting ships in a package quantity of five, making it practical for service trucks, maintenance shops, and jobsite inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e300 psi liquid and gas pressure rating for reliable service in pressurized systems\u003c\/li\u003e\n  \u003cli\u003e150 psi steam pressure rating supports steam distribution applications\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and resistance to vibration and impact\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish offers corrosion resistance in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eSquare head design allows positive wrench grip for secure installation and removal\u003c\/li\u003e\n  \u003cli\u003eClass 150 fitting meets standard pipe fitting classification for threaded iron systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-stock fitting compatible with 3\/8 inch NPT threaded pipe systems in liquid, gas, and steam service within Class 150 malleable iron piping assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters working under applicable plumbing and mechanical codes such as the IPC or IFGC. Shut off and depressurize the line completely before installing or removing any threaded pipe plug. Apply appropriate thread sealant or PTFE tape to the male threads before seating the plug, and tighten with a wrench to a secure fit without over-torquing the fitting. Inspect for leaks after restoring system pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Square Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid and Gas Pressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSteam Pressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720513945906,"sku":"13121","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bae77e33de1a120d9230439b1a523c6a.jpg?v=1788565320","url":"https:\/\/voomisupply.com\/products\/value-collection-13121-malleable-iron-square-pipe-plug-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
