Machined from 304 stainless steel, it provides solid corrosion resistance in both wet and dry environments. The male NPT (MNPT) threaded end connects directly into female-threaded fittings, valves, and manifolds. Rated to 150 psi, this plug is suited for low- to medium-pressure service. The square head drive allows installation and removal with a standard wrench, making it a practical choice for service technicians working in tight access points.\u003c\/p\u003e\u003cp\u003eThis plug is commonly used to cap unused ports on valve bodies, pipe tees, manifolds, and distribution headers in residential and light commercial plumbing and HVAC systems. It is also appropriate for industrial fluid and gas lines where a corrosion-resistant, threaded closure is required. Plumbers, pipefitters, and HVAC technicians install this fitting during new construction, system modifications, and service calls where ports need to be blanked off cleanly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction for corrosion resistance in wet and industrial environments\u003c\/li\u003e\n\u003cli\u003eSquare head drive for easy installation and removal with a standard wrench\u003c\/li\u003e\n\u003cli\u003eMNPT threaded connection for direct fitment into female NPT ports\u003c\/li\u003e\n\u003cli\u003e150 psi pressure rating suitable for low- to medium-pressure pipe systems\u003c\/li\u003e\n\u003cli\u003eISO standard compliance for dimensional consistency\u003c\/li\u003e\n\u003cli\u003eCompact 1\/4 inch fitting size for small-diameter port applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded pipe plug for 1\/4 inch female NPT ports found in standard plumbing, HVAC, and industrial piping assemblies conforming to ISO fitting standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters and should follow applicable IPC or IFGC guidelines for the system type. Depressurize and drain the line before removing or installing any threaded plug. Apply thread sealant tape or pipe dope to the MNPT threads before hand-tightening, then snug with a wrench — do not overtighten stainless steel threads to avoid galling. Inspect the female port threads for damage before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: K417A-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51691567087922,"sku":"K417A-04","price":23.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0a27084d023b1bda7368bb9c4f390e5.jpg?v=1788287066","url":"https:\/\/voomisupply.com\/products\/merit-brass-k417a-04-square-head-pipe-plug-1-4-in-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
