Featuring a 3\/4 inch male MNPTF (Dryseal National Pipe Taper Fuel) thread connection, this hex plug is rated for a maximum working pressure of 5,500 psi, making it suitable for demanding hydraulic, pneumatic, and fluid power applications. The 1-1\/8 inch hex size accommodates standard wrenches for secure installation. With an overall length of 2 inches, this compact fitting provides a reliable, leak-resistant seal when correctly torqued into a mating female port. Licensed plumbers, pipefitters, and hydraulic system technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis hex plug is used in industrial piping systems where a threaded port must be permanently or temporarily sealed. Common applications include hydraulic manifolds, pneumatic distribution blocks, fluid power circuits, and high-pressure test systems. The MNPTF thread form provides a pressure-tight metal-to-metal seal without requiring additional sealant in many configurations, though installation practices should follow system requirements and applicable standards. It is suited for both original equipment builds and field service work across a range of industrial environments.\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 fluid power service\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch MNPTF male thread for a pressure-tight dryseal connection\u003c\/li\u003e\n  \u003cli\u003eStraight hex plug fitting shape for direct port sealing\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch hex size for use with standard open-end or box wrenches\u003c\/li\u003e\n  \u003cli\u003e2 inch overall length for compact installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003eSold and packaged as a single unit\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 piping and fluid power systems requiring a 3\/4 inch MNPTF male thread hex plug 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 in accordance with applicable codes and system specifications. De-energize and fully depressurize the system before removing or installing any fitting. Use the 1-1\/8 inch hex to drive the plug with a properly sized wrench — avoid pipe wrenches on the hex body, which can deform the fitting. Inspect threads for damage before installation and verify the thread form of the mating port is compatible with MNPTF before seating the plug.\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\u003eFitting Shape\u003c\/strong\u003e: Straight\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 5,500 psi\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\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\/4 FF-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541188510002,"sku":"3\/4 FF-S","price":21.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27213ef293f47b52954872f64c983574_37299f0f-f884-4f66-a156-032805a0bf14.jpg?v=1785869756","url":"https:\/\/voomisupply.com\/products\/parker-3-4-ff-s-hex-plug-5500-psi-mnptf-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
