Machined from brass with a 3\/8 inch MNPTF (Male National Pipe Thread Fuel) connection, this plug seals open pipe ports while maintaining a rated working pressure of 1000 psi. The hollow hex drive allows installation with a standard hex key or socket, making it well suited for tight-clearance applications. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting where a flush or recessed plug profile is needed without sacrificing pressure integrity.\u003c\/p\u003e\n\u003cp\u003eThe 219P-6 is used in hydraulic, pneumatic, fuel, and general fluid-handling systems where a 3\/8 inch male threaded port needs to be capped or temporarily sealed. It performs across a wide temperature range, from -65 degrees F to 250 degrees F, making it appropriate for both refrigeration-adjacent piping and moderate-heat fluid systems in commercial and industrial settings. Its brass construction resists corrosion in water, oil, and fuel service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1000 psi maximum working pressure for reliable port sealing under system load\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in water, oil, and fuel service\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch MNPTF thread conforms to SAE J530 and SAE J531 standards\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eHollow hex drive enables installation in confined spaces with a hex key or socket\u003c\/li\u003e\n  \u003cli\u003eCompact, low-profile design suits tight manifold and valve body applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for any 3\/8 inch MNPTF-threaded pipe port in hydraulic, pneumatic, fuel, or general fluid-handling systems requiring a hollow hex plug closure.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter following applicable codes. Depressurize and isolate the system completely before removing or installing any threaded plug. Apply thread sealant appropriate for the fluid service — consult the system manufacturer or applicable code for sealant type. Do not overtighten; use a calibrated torque method and follow standard practices for brass fittings to avoid galling or thread damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hollow Hex Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPTF\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: 1000 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: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 219P-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541459304754,"sku":"219P-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/678d9f25931d6040cc1ac83296b50627_f0031e57-ad44-4c7f-8a7f-2d8f48e28dca.jpg?v=1785876733","url":"https:\/\/voomisupply.com\/products\/parker-219p-6-hollow-hex-plug-3-8-inch-mnptf-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
