Machined to a 1-1\/4-11-1\/2 MNPT thread, it meets ASME B16.14-1991 dimensional standards and carries a 150 lb pressure class rating. The countersunk head design allows the plug to sit flush with or below the mating surface, keeping the installation clean and low-profile. A 3\/4-inch square drive socket is required for installation and removal. This fitting is rated for service from -20 degrees F to 350 degrees F, covering a wide range of commercial and industrial pipe applications. Plumbers and pipefitters install this plug as a permanent or serviceable closure on branch outlets, test ports, and capped-off run ends.\u003c\/p\u003e\u003cp\u003eThis plug is used in black steel piping systems in residential, commercial, and light industrial settings. Common applications include gas distribution piping, compressed air lines, and hydraulic systems where a low-profile threaded closure is required. Its black steel construction and 150 lb pressure class make it suitable for moderate-pressure service lines. The ASME B16.14-1991 compliance ensures dimensional interchangeability with standard fittings from other manufacturers in the same pressure class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4-11-1\/2 MNPT thread for direct engagement with standard female NPT fittings\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class per ASME B16.14-1991\u003c\/li\u003e\n\u003cli\u003eCountersunk head sits flush or below mating surface for low-profile installations\u003c\/li\u003e\n\u003cli\u003e3\/4-inch square socket drive for installation and removal with a standard socket wrench\u003c\/li\u003e\n\u003cli\u003eRated -20 degrees F to 350 degrees F for broad service temperature range\u003c\/li\u003e\n\u003cli\u003eBlack steel construction suitable for gas, air, and hydraulic line applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for black steel piping systems using standard 1-1\/4 in MNPT threaded connections rated at 150 lb pressure class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber or pipefitter. Depressurize and isolate the pipe system before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads per applicable code requirements such as IFGC or IPC. Use a 3\/4-inch square drive socket and torque wrench for proper engagement; do not over-drive as this may damage the female fitting threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 1-1\/4-11-1\/2 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -20 degrees F to 350 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.365 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: ASME B16.14-1991\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 67636\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950315995442,"sku":"67636","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f98fc8488d5cc864521b49c5d77777c_6b7fbc31-3654-4932-8d93-a0306e7531a8.jpg?v=1791713112","url":"https:\/\/voomisupply.com\/products\/midland-industries-67636-countersunk-plug-1-1-4-in-mnpt-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
