Constructed from zinc-plated steel, this plug delivers a maximum working pressure rating of 3000 psi, making it suitable for demanding pressure-containment applications. With an overall length of 2-1\/2 inches and a 1-3\/4 inch hex drive, it accepts a standard wrench for secure installation. It is installed by pipefitters, hydraulic technicians, and industrial maintenance mechanics to cap off unused ports or temporarily block lines during system service.\u003c\/p\u003e\u003cp\u003eThis hex plug is used in industrial fluid power systems, hydraulic manifolds, plumbing assemblies, and pipe distribution networks where reliable port sealing is required. It is appropriate for both maintenance and new installation work in light industrial, heavy manufacturing, and processing environments. The MNPTF thread form provides a pressure-tight mechanical seal without requiring additional sealant in many applications, though thread sealant is commonly applied per job requirements and applicable standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3000 psi maximum working pressure rating for demanding hydraulic and pneumatic applications\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction provides corrosion resistance in typical industrial environments\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch MNPTF male thread for dryseal pressure-tight connections\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch hex drive accepts standard wrenches for fast, secure installation\u003c\/li\u003e\n\u003cli\u003eStraight fitting shape for direct port sealing without offset\u003c\/li\u003e\n\u003cli\u003eMeets SAE 140137 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or maintenance fitting for industrial hydraulic and pneumatic piping systems using 1-1\/4 inch MNPTF female-threaded ports rated to 3000 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter, hydraulic technician, or industrial mechanic. Depressurize and de-energize the system fully before removing or installing any threaded fittings. Apply thread sealant or PTFE tape as required by the application and in accordance with applicable standards.
