It features female NPT (FNPT) end connections on both ends and reduces from 2 inches nominal on the larger end to 1-1\/2 inches nominal on the smaller end. Rated for 150 lb service, this fitting carries a black oxide finish that provides a base level of corrosion resistance in dry and low-moisture environments. It is commonly installed by licensed plumbers and pipefitters working on schedule 40 threaded pipe assemblies.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial pipe installations where a threaded connection is required between two different pipe diameters. Typical applications include water distribution lines, hydronic heating systems, fire protection piping, and general mechanical piping where a 2-inch to 1-1\/2-inch diameter transition is needed. The FNPT configuration allows direct threading onto standard NPT pipe without additional adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 2 inches nominal to 1-1\/2 inches nominal in a single fitting\u003c\/li\u003e\n  \u003cli\u003eFemale NPT (FNPT) threads on both ends for standard threaded pipe connection\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suitable for general plumbing and mechanical piping service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and impact resistance compared to cast iron\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for base corrosion protection in low-moisture environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use fitting for 150 lb rated malleable iron threaded pipe systems using NPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter. Shut off system pressure and drain the line before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly.
