The fitting seals an open male NPT port with a pressure rating of 150 psi, making it a dependable choice for low-to-moderate pressure service in plumbing, HVAC, and industrial fluid systems. At 0.625 inches in length and 1\/8 inch in size, it is a compact fitting suited for tight spaces. Plumbers, pipefitters, and HVAC technicians install this plug when capping unused branch ports or sealing test ports after commissioning.\u003c\/p\u003e\u003cp\u003eThis hex plug is appropriate for residential and light commercial applications where a 1\/8 inch MNPT threaded closure is needed. Common install scenarios include capping unused gauge ports on hydronic heating systems, sealing tee branches during pressure testing, and closing off unused connections on manifolds or valves. The external hex drive allows for standard wrench installation without requiring specialty tools. Its 304 stainless steel construction suits applications involving mild corrosives, moisture exposure, or environments where carbon steel fittings are not acceptable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction resists corrosion in wet and mildly corrosive service environments\u003c\/li\u003e\n\u003cli\u003e1\/8 inch MNPT threaded end connection for compatibility with standard NPT pipe ports\u003c\/li\u003e\n\u003cli\u003e150 psi pressure rating suitable for low-to-moderate pressure plumbing and HVAC applications\u003c\/li\u003e\n\u003cli\u003eHex drive profile allows installation with a standard open-end or box wrench\u003c\/li\u003e\n\u003cli\u003eCompact 0.625 inch length fits tight pipe configurations and panel-mounted valve bodies\u003c\/li\u003e\n\u003cli\u003eISO-rated fitting manufactured to recognized dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard MNPT hex plug for use in any 1\/8 inch female NPT threaded port rated at or above 150 psi, consistent with typical residential and light commercial plumbing and HVAC piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed plumber or pipefitter should install threaded pipe fittings in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the system fully before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation, and tighten using a properly sized wrench on the hex flats. Do not over-tighten stainless steel threads, as galling can occur without proper lubrication or sealant.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: MNPT (Male National Pipe Thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: K417H-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51544439750962,"sku":"K417H-02","price":25.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75f319add51adbf85e1106acf1a8e56c.jpg?v=1785926571","url":"https:\/\/voomisupply.com\/products\/merit-brass-k417h-02-hex-plug-1-8-in-304-ss-mnpt-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
