It features a male NPT (MNPT) outer thread and a female NPT (FNPT) inner thread, allowing it to close off a pipe run while leaving the internal port accessible if needed. Rated at Class 125, this plug suits water, oil, gas, and air service lines where a reliable, pressure-appropriate threaded seal is required. The square head profile provides a positive wrench flat for installation and removal without slipping. Licensed plumbers and pipefitters are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for residential and light commercial plumbing, HVAC hydronic systems, compressed air distribution, and general industrial pipe assemblies. It is most commonly used to cap unused branch tee outlets, plug test ports, or terminate dead-end pipe runs in Class 125 piping configurations. The 3\/8 inch NPT size fits standard 3\/8 inch threaded pipe fittings and valves commonly found in domestic water supply and heating system branch lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch MNPT x FNPT end connections for standard threaded pipe installation\u003c\/li\u003e\n  \u003cli\u003eClass 125 pressure rating suitable for common water, air, oil, and gas service\u003c\/li\u003e\n  \u003cli\u003eSquare head design provides flat wrench engagement for secure torquing\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers corrosion resistance in wet and humid environments\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight fitting at 0.05 pounds for easy handling and stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3\/8 inch NPT threaded pipe systems rated at Class 125 service conditions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC codes for the service fluid.
