Finished in black, this Class 150 fitting carries a liquid and gas pressure rating of 300 psi, making it suitable for use in a wide range of piping applications involving air, water, gas, or steam within its rated limits. Licensed plumbers, pipefitters, and HVAC technicians install this type of plug when capping unused tapped ports on valves, manifolds, fittings, and pipe assemblies. The malleable iron construction provides reliable durability in standard commercial and industrial piping environments.\u003c\/p\u003e\n\u003cp\u003eThe 13371 square plug is used in residential and commercial piping installations wherever a threaded end connection must be sealed off. Typical applications include capping spare ports on gas manifolds, water distribution headers, hydronic heating systems, and compressed air lines. The square head profile allows standard wrench engagement for proper torque without the need for specialty tools. This fitting ships in a quantity of 5 per package, which suits service techs and contractors who frequently stock common plug sizes on their trucks or in parts inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction with black finish for corrosion resistance in standard piping environments\u003c\/li\u003e\n  \u003cli\u003eClass 150 rated with 300 psi liquid and gas pressure capacity\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch threaded end connection for direct engagement with standard NPT female ports\u003c\/li\u003e\n  \u003cli\u003eSquare head profile accepts standard wrenches for installation and removal\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 5, suited for service stock and small-job replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Class 150 malleable iron threaded square plug compatible with 3\/8-inch NPT female threaded pipe ports in typical plumbing, HVAC, and gas piping installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of threaded pipe plugs should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, and IFGC requirements.
