It features a 3\/8 inch male MNPTF (Dryseal) thread that forms a pressure-tight seal without a separate sealant, though thread sealant tape is commonly applied in field installations. Rated to 6,000 psi maximum working pressure, this plug is built for demanding industrial service. The hex drive design allows installation with standard wrenches. Weighing 0.2 pounds, it is a compact, single-piece fitting suited for inline port sealing tasks across a wide range of fluid power and instrumentation applications.\u003c\/p\u003e\u003cp\u003eThis hex plug is used to cap or block unused ports on valves, manifolds, cylinders, pumps, and other hydraulic or pneumatic components. It is appropriate for both industrial plant maintenance and mobile equipment applications where a reliable, leak-free port closure is required. The MNPTF thread classification makes it well suited for high-pressure instrumentation lines and fluid transfer systems where pressure integrity is critical. Licensed pipefitters, hydraulic system technicians, and industrial maintenance mechanics are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6,000 psi maximum working pressure rating for high-pressure hydraulic and pneumatic service\u003c\/li\u003e\n\u003cli\u003e3\/8 inch MNPTF (Dryseal National Pipe Taper Fuel) male thread for pressure-tight connections\u003c\/li\u003e\n\u003cli\u003eStraight hex plug configuration for straightforward port sealing\u003c\/li\u003e\n\u003cli\u003e3\/4 inch hex size for use with standard open-end or box wrenches\u003c\/li\u003e\n\u003cli\u003eOverall length of 1-7\/16 inches for compact fitment in tight port locations\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.2 pounds for easy single-hand installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or maintenance fitting for hydraulic and pneumatic systems with 3\/8 inch MNPTF ported connections rated to 6,000 psi or below.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the system completely before removing or installing any fittings. Apply thread sealant tape or an appropriate anaerobic thread sealant to the male threads before installation; do not overtighten, as MNPTF threads are tapered and can crack ports if over-torqued. Verify system pressure rating does not exceed the 6,000 psi maximum working pressure of this fitting before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMale Thread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPTF\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\u003eHex Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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 FF-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538900255026,"sku":"3\/8 FF-S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f9b09958c70a85ef69c2ee4c2a68d6a.jpg?v=1785829121","url":"https:\/\/voomisupply.com\/products\/parker-3-8-ff-s-hex-plug-3-8-inch-mnptf-6000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
