Constructed from zinc-plated steel, this fitting uses an MNPTF (Male National Pipe Thread Fuel) connection and is rated to a maximum working pressure of 5,500 psi. The hex design allows for standard wrench engagement during installation and removal. At 1-3\/4 inches overall length with a 1-1\/8 inch hex size, it is compact enough for tight plumbing assemblies while delivering the structural integrity needed in high-pressure hydraulic, pneumatic, and fluid power systems. Licensed plumbers, pipefitters, and hydraulic technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis hex plug is suited for use in industrial fluid power systems, hydraulic lines, and high-pressure pneumatic circuits where a 3\/4 inch to 1\/4 inch male thread termination point is required. The MNPTF thread form provides a pressure-tight seal on fuel, oil, water, and air service lines. It is appropriate for both OEM assembly environments and field service repairs where a durable, zinc-plated steel plug is specified to cap or reduce threaded ports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated to 5,500 psi maximum working pressure for demanding hydraulic and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel construction provides corrosion resistance in industrial environments\u003c\/li\u003e\n  \u003cli\u003eMNPTF thread form delivers a pressure-tight connection on fuel, oil, and air service lines\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch hex size allows engagement with standard wrenches for torque-controlled installation\u003c\/li\u003e\n  \u003cli\u003eStraight fitting shape simplifies port capping and thread reduction in linear plumbing runs\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 140137 standards for dimensional and performance consistency\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 assemblies using 3\/4 inch to 1\/4 inch MNPTF threaded ports rated to 5,500 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or hydraulic technician. Depressurize and isolate the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape compatible with the service fluid before threading the plug into the port. Do not over-tighten; follow applicable IFGC, IPC, or system manufacturer torque guidelines for the specific service application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5,500 psi\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 x 1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc-Plated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 140137\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\/4 X 1\/4 FF-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540254654770,"sku":"3\/4 X 1\/4 FF-S","price":84.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30ce649f9ac90080bf218daaa527e47a.jpg?v=1785850378","url":"https:\/\/voomisupply.com\/products\/parker-3-4-x-1-4-ff-s-hex-plug-mnptf-5500-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
