Rated at 150 lb, this cap features a female NPT (FNPT) end connection and a hot-dip galvanized finish that resists corrosion in wet or outdoor environments. Sized for 3-inch nominal pipe, it is a standard fitting used in low-pressure piping systems for gas, water, air, and steam service. Licensed plumbers and pipefitters install these fittings during new construction, system modifications, or temporary line isolation.\u003c\/p\u003e\n\u003cp\u003eThis pipe cap is suited for residential and light commercial plumbing, gas distribution, compressed air, and hydronic heating applications where a 3-inch threaded termination is required. The galvanized coating makes it appropriate for exposed or damp locations where bare iron would be prone to rust. It is a domestically produced fitting conforming to standard malleable iron pipe fitting dimensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch nominal size closes standard threaded pipe ends cleanly\u003c\/li\u003e\n  \u003cli\u003eFNPT end style threads directly onto male-threaded pipe or nipple\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suitable for low-pressure water, air, gas, and steam service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and impact resistance over cast iron\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish resists corrosion in wet and outdoor installations\u003c\/li\u003e\n  \u003cli\u003eDomestically produced fitting for projects requiring domestic-origin components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fitting for 3-inch FNPT threaded piping systems using 150 lb malleable iron fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter.
