This plug is used to seal off open pipe ends in plumbing, HVAC, and light industrial piping systems. The square head drive allows installation with a standard wrench, making it straightforward to torque into fittings without specialty tools. Brass construction provides corrosion resistance and compatibility with a wide range of fluids, making it a reliable choice for potable water, gas, and hydraulic service lines where a Class 125 pressure rating is appropriate.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for residential and light commercial piping applications where a threaded pipe end needs to be capped or blanked off. Common install scenarios include capping unused branch outlets on water supply lines, plugging test ports on HVAC piping, and sealing distribution manifold ports during system configuration or repair. Plumbers, pipefitters, and HVAC technicians regularly use Class 125 threaded brass plugs in both new construction and service work. The 3\/4 inch MNPT thread engages standard Schedule 40 fittings and valves with matching female NPT ports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch threaded fitting size in MNPT x FNPT configuration\u003c\/li\u003e\n  \u003cli\u003eClass 125 pressure rating suitable for water, gas, and light hydraulic service\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers corrosion resistance across a broad range of media\u003c\/li\u003e\n  \u003cli\u003eSquare head drive accepts standard open-end or adjustable wrench for installation\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type for secure, leak-resistant sealing of open pipe ends\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use fitting for standard 3\/4 inch female NPT threaded pipe ports in Class 125 plumbing, HVAC, and light industrial piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC codes for the service type. Shut off and depressurize the piping system completely before removing or installing any threaded pipe plugs. Apply thread sealant tape or pipe dope appropriate for the fluid service to the MNPT threads before engagement. Do not overtighten brass fittings, as the material can deform; hand-snug plus wrench tightening to achieve a leak-free seal is the standard practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Square Head Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: MNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C117-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51538971361586,"sku":"C117-12","price":26.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d109fc0fed7f9534b504faf45cc1a48.jpg?v=1785831378","url":"https:\/\/voomisupply.com\/products\/merit-brass-c117-12-brass-square-head-plug-3-4-in-class-125","provider":"Voomi Supply","version":"1.0","type":"link"}
