It features a 1\/4 inch MNPT male thread that engages a matching FNPT female fitting, and it is rated at 125 psi at Class 125 service conditions. The square head drive profile allows installation and removal with a wrench or socket without relying on a slotted or hex recess. The plug is fully lead free, meeting requirements for potable water and other lead-sensitive applications. At 0.04 pounds, it is a compact, single-piece brass fitting suited for frequent use by licensed plumbers and pipefitters.\u003c\/p\u003e\n\u003cp\u003eThis plug is used wherever a threaded pipe port needs to be capped or blanked off. Common applications include sealing unused tee outlets, test ports, gauge ports, and branch connections in residential and light commercial plumbing, hydronic heating, compressed air, and general fluid service lines. The Class 125 pressure rating makes it appropriate for standard low-pressure service in both water and air systems. It is sold individually with a minimum order quantity of 6 units, making it practical for stocking in a service van or shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch MNPT threaded connection engages standard FNPT female fittings\u003c\/li\u003e\n  \u003cli\u003eSquare head drive profile for positive wrench grip during installation and removal\u003c\/li\u003e\n  \u003cli\u003e125 psi pressure rating at Class 125 service conditions\u003c\/li\u003e\n  \u003cli\u003eLead free construction suitable for potable water applications\u003c\/li\u003e\n  \u003cli\u003eSolid brass body resists corrosion in water, air, and light fluid service\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds for easy handling and high-volume stocking\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 any standard 1\/4 inch FNPT threaded port in Class 125 brass, iron, or compatible piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed plumber or qualified pipefitter should install this plug in accordance with applicable IPC and local plumbing code requirements.
