Machined for MNPTF (male national pipe taper fuel) connections, this fitting accepts a 3\/4 inch male thread and is rated to a maximum working pressure of 5,500 psi. The hollow hex design allows for standard hex wrench installation without the need for specialized tooling. At 5\/8 inch overall length and a 9\/16 inch hex size, it fits into tight plumbing assemblies common in hydraulic, pneumatic, and industrial fluid systems. Plumbers, pipefitters, and fluid system technicians install this type of plug to cap or test ports in high-pressure lines.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for industrial and commercial pipe applications where a threaded port closure is required on MNPTF-configured fittings. Typical installations include hydraulic manifolds, pneumatic panels, test port closures, and instrumentation tie-ins operating at or below 5,500 psi. The compact 5\/8 inch length makes it a practical choice in space-constrained panel or manifold assemblies. It ships as a single unit, making it appropriate for spot replacements or low-quantity service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated to 5,500 psi maximum working pressure for high-pressure industrial service\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch MNPTF male thread connection provides a tapered, leak-resistant seal\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch hex size accommodates standard wrench or socket installation\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch overall length suits tight-clearance manifold and panel installations\u003c\/li\u003e\n  \u003cli\u003eHollow hex body design simplifies torque application during installation\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 systems using 3\/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 licensed pipefitter or qualified fluid systems technician. Depressurize and isolate the system completely before removing or installing any threaded plug. Apply appropriate thread sealant compatible with the system fluid before threading the plug into the port. Follow applicable industry codes and the system manufacturer guidelines for torque and sealant procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hollow Hex Plug\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: 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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 HHP-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544066818354,"sku":"3\/4 HHP-S","price":22.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a460d947d013ffaa486d7be534b7de1.jpg?v=1785923572","url":"https:\/\/voomisupply.com\/products\/parker-3-4-hhp-s-hollow-hex-plug-3-4-in-mnptf-5500-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
