It accepts a 1-1\/4 x 1 inch MNPTF (Male National Pipe Thread Fuel) connection and carries a maximum working pressure rating of 3000 psi. The hex drive design allows for standard wrench installation, making it a practical solution for high-pressure hydraulic, pneumatic, and fluid transfer lines. Plumbers, pipefitters, and hydraulic system technicians install this fitting when capping or blocking off a port in a pressurized line or manifold assembly.\u003c\/p\u003e\n\u003cp\u003eThis hex plug is suited for industrial and commercial piping applications where a reliable MNPTF threaded port closure is required. Typical installation scenarios include hydraulic manifolds, fluid power systems, and high-pressure plumbing assemblies. The straight fitting shape and standardized thread form make it compatible with a wide range of pipe system configurations in both shop and field environments. It conforms to SAE 140137 standards, which is relevant for hydraulic and fluid power component applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3000 psi maximum working pressure rating for high-pressure system applications\u003c\/li\u003e\n  \u003cli\u003eMNPTF connection type provides a tapered male thread for a secure, fuel-rated seal\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch hex size accommodates standard open-end or combination wrenches\u003c\/li\u003e\n  \u003cli\u003eStraight fitting shape for direct port closure without offset or angle\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 140137 standards for hydraulic and fluid power fittings\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 2-7\/16 inches for installations with limited clearance\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 hydraulic systems requiring a 1-1\/4 x 1 inch MNPTF hex plug rated to 3000 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed pipefitters or hydraulic technicians. Always depressurize and isolate the system completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape rated for the fluid type and pressure range in use. Do not overtighten, as damage to the tapered thread can compromise the pressure seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1-1\/4 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MNPTF\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\u003eHex Size\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 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: 1 1\/4 X 1 FF-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542449488178,"sku":"1 1\/4 X 1 FF-S","price":46.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30ce649f9ac90080bf218daaa527e47a_41eef0ec-de41-48f3-b2ea-ed8284272173.jpg?v=1785900866","url":"https:\/\/voomisupply.com\/products\/parker-1-1-4-x-1-ff-s-hex-plug-3000-psi-mnptf","provider":"Voomi Supply","version":"1.0","type":"link"}
