Manufactured from steel, this straight-pattern plug accepts a 3\/8 inch male NPT (MNPT) thread and is rated for working pressures up to 6,000 psi. The square head drive allows installation and removal with standard wrenches or sockets without requiring a specialized driver. Licensed plumbers, pipefitters, and hydraulic technicians use this plug to cap unused ports on manifolds, valves, pumps, and cylinders during assembly, maintenance, or system modification.\u003c\/p\u003e\u003cp\u003eThis plug is suited for use in industrial hydraulic circuits, pneumatic systems, and plumbing assemblies where a dependable threaded closure is required. Its straight fitting shape makes it appropriate for direct port-sealing applications without adapters. The rated operating temperature range of -40 degrees F to 250 degrees F covers most indoor industrial environments and many mobile hydraulic equipment applications. Typical installations include capping spare ports on hydraulic power units, valve bodies, and pipe manifolds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6,000 psi maximum working pressure for demanding hydraulic and industrial service\u003c\/li\u003e\n\u003cli\u003e3\/8 inch MNPT thread for direct installation into standard NPT-threaded female ports\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability in high-pressure environments\u003c\/li\u003e\n\u003cli\u003eSquare head drive allows use of common wrenches and sockets\u003c\/li\u003e\n\u003cli\u003eStraight fitting shape simplifies direct port closure without adapters\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service plug for industrial hydraulic and fluid power systems with 3\/8 inch female MNPT threaded ports rated to accept fittings up to 6,000 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber following applicable codes such as the IPC or relevant hydraulic system standards. Depressurize and isolate the system completely before removing or installing any threaded plugs. Apply appropriate thread sealant or PTFE tape to the MNPT threads per the system requirements before installation. Do not overtighten — use a torque value specified by the system manufacturer for the port size and material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Square Head Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6,000 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: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FF4177-06S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51541701787954,"sku":"FF4177-06S","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d6def2fa6f605976cee931a376c7ca7.jpg?v=1785882583","url":"https:\/\/voomisupply.com\/products\/eaton-ff4177-06s-square-head-pipe-plug-3-8-in-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
