Threaded with a 3\/4-inch male MNPTF connection, this fitting creates a pressure-tight closure rated to 1,000 psi maximum working pressure. The brass construction resists corrosion and handles a wide service temperature range, from -65 degrees F to 250 degrees F. It meets SAE J530 and SAE J531 standards. Licensed plumbers, pipefitters, and fluid power technicians install this type of fitting during system assembly, maintenance, or pressure testing to cap unused ports and branch lines.\u003c\/p\u003e\n\u003cp\u003eThis hex plug is suited for use in hydraulic, pneumatic, fuel, and general-purpose fluid piping systems where a threaded pipe port needs to be sealed. The MNPTF thread profile provides a dry-seal connection without requiring additional sealant tape or compound, though jobsite practice may vary. It is commonly installed in industrial machinery, plumbing headers, compressor manifolds, and test bench assemblies where 3\/4-inch NPT ports must be closed off reliably under moderate to high pressure conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1,000 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch male MNPTF dry-seal thread connection\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in fluid service\u003c\/li\u003e\n  \u003cli\u003eService temperature range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J530 and SAE J531 standards\u003c\/li\u003e\n  \u003cli\u003eHex head profile accepts standard wrench for controlled installation torque\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard MNPTF hex plug for 3\/4-inch pipe thread ports in hydraulic, pneumatic, and general-purpose fluid piping systems conforming to SAE J530 and SAE J531 thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber, pipefitter, or fluid power technician using an appropriately sized open-end or box wrench on the hex head. Depressurize and isolate the system completely before installing or removing any threaded fittings. MNPTF threads are designed for dry-seal engagement, but verify jobsite specifications and applicable codes such as the IPC or IFGC before omitting thread sealant. Do not overtighten, as brass threads can strip or crack the fitting body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J530, SAE J531\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 218P-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544492933426,"sku":"218P-12","price":21.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/413de9e7ff942f4cbd9caf44e3f7eec1_e3fc74d3-1e6d-42f0-b8b5-81ab8b27ce59.jpg?v=1785928016","url":"https:\/\/voomisupply.com\/products\/parker-218p-12-hex-plug-3-4-inch-mnptf-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
