Manufactured to accept a 3\/8 inch male MNPTF (Dryseal National Pipe Taper Fuel) thread connection, this plug is rated to a maximum working pressure of 6000 psi, making it suitable for high-pressure hydraulic and pneumatic lines. The hollow hex drive design allows installation and removal with a standard hex key. Overall length is 7\/16 inches and hex size is 5\/16 inches. Licensed plumbers, pipefitters, and hydraulic system technicians install this fitting as part of pressure line assemblies, test port closures, or system cap-offs.\u003c\/p\u003e\n\u003cp\u003eThis plug is intended for industrial pipe and fluid power applications where a male MNPTF threaded closure is required. Common use cases include sealing unused ports on manifolds, hydraulic valve bodies, and high-pressure fluid distribution blocks in both fixed and mobile equipment environments. The 6000 psi pressure rating makes it appropriate for demanding hydraulic service. Its compact dimensions allow installation in space-constrained port locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6000 psi maximum working pressure rating for high-pressure hydraulic and pneumatic service\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch MNPTF male thread connection for dryseal pipe thread fitment\u003c\/li\u003e\n  \u003cli\u003eHollow hex drive design — 5\/16 inch hex size — for installation with a standard hex key\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 7\/16 inches suits tight port access\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction suitable for port sealing on manifolds and valve bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for industrial pipe and fluid power assemblies requiring a 3\/8 inch MNPTF male threaded hollow hex plug rated to 6000 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed pipefitter, hydraulic technician, or plumber depending on the application. Depressurize and isolate the system completely before removing or installing any threaded pipe plug. Use a correctly sized 5\/16 inch hex key to avoid rounding the drive. Follow applicable industry standards and torque practices for MNPTF dryseal thread connections — thread sealant use should follow the system fluid and pressure requirements per manufacturer guidance.\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\u003eConnection Type\u003c\/strong\u003e: MNPTF\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 6000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\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: 3\/8 HHP-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542320152882,"sku":"3\/8 HHP-S","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6355ea243b3497060c8fbc849b9d2cd8.jpg?v=1785898043","url":"https:\/\/voomisupply.com\/products\/parker-3-8-hhp-s-hollow-hex-plug-3-8-in-mnptf-6000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
