It features a 1-inch male National Pipe Taper (MNPT) connection with a 1-11-1\/2 thread pitch, meeting ASME B16.14-1991 dimensional standards. Constructed from steel with a zinc-plated finish for corrosion resistance, this plug is rated for a pressure class of 150 lb and an operating temperature range of -20 to 350 degrees F. Plumbers, pipefitters, and mechanical contractors install this fitting when blanking off a pipe run or isolating a branch during system testing or permanent closure.\u003c\/p\u003e\u003cp\u003eThe 66775 is suited for residential and light commercial plumbing, hydronic heating, compressed air, and low-pressure gas piping applications where a threaded closure is required. Its hex head design allows installation and removal with standard hex wrenches or pipe wrenches, making it a practical choice for both permanent installations and service work. The zinc-plated finish provides additional protection in damp or mildly corrosive environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid steel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1-inch MNPT connection with 1-11-1\/2 thread pitch for secure, leak-tight sealing\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class rating suitable for standard piping systems\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -20 to 350 degrees F\u003c\/li\u003e\n\u003cli\u003eHex head design allows installation with standard wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME B16.14-1991 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install fitting for 1-inch MNPT threaded pipe systems rated at 150 lb pressure class in galvanized steel fitting assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Always depressurize and isolate the pipe section before installing or removing threaded plugs. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before installation. Do not overtighten, as this can crack fittings or damage threads in the mating connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 1-11-1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.31 inches\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 to 350 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel, Zinc-Plated\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: 66775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950731624754,"sku":"66775","price":15.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8c23bdde93792d96686a40721c7396f_c463e399-3495-4b1f-8b96-094048aa1886.jpg?v=1791723276","url":"https:\/\/voomisupply.com\/products\/midland-industries-66775-hex-head-plug-1-in-mnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
