Sized at 1\/2 inch with NPT threads, this cap seals the end of a pipe run or temporarily closes off a branch line. At 0.12 pounds, it is a compact fitting suited for tight spaces in mechanical rooms, utility chases, and process piping. Licensed plumbers and pipefitters install this fitting where a durable, code-compliant termination is required on a threaded iron pipe system.\u003c\/p\u003e\n\u003cp\u003eThis cap is used in residential and light commercial plumbing, steam distribution, hydronic heating, gas distribution, and compressed air piping. The malleable iron construction handles the thermal cycling common in steam and hot-water systems. The black finish is standard for gas and steam piping applications where a galvanized fitting is not specified. It installs on any standard 1\/2 inch NPT threaded pipe end.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass 150 pressure rating: 150 psi for steam, liquid, and gas service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction for durability under thermal cycling\u003c\/li\u003e\n  \u003cli\u003eThreaded connection (NPT) for fast, tool-only installation\u003c\/li\u003e\n  \u003cli\u003eBlack finish standard for gas and steam piping applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch fitting size for common residential and light commercial pipe runs\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.12 pounds — easy to stock and handle in the field\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 1\/2 inch NPT threaded iron pipe systems rated at Class 150.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the service type.
