Rated at 150 lb, this fitting accepts female iron pipe (FIP) connections on both ends, making it a standard choice for directional changes in threaded piping runs. Malleable iron construction provides reliable strength and durability in gas, air, and compatible fluid distribution systems. Licensed plumbers and pipefitters install this fitting as part of threaded iron pipe assemblies where a square 90-degree turn is required.\u003c\/p\u003e\n\u003cp\u003eThis elbow is suited for use in low-pressure threaded piping systems including natural gas distribution, compressed air lines, and compatible water supply applications. The 3\/4 inch FIP x FIP configuration fits standard 3\/4 inch NPT-threaded pipe and is a common size in both new construction and retrofit installations. It is appropriate for residential gas supply lines, commercial mechanical rooms, and light industrial piping layouts where malleable iron fittings meet code requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow geometry for square directional changes in threaded piping runs\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure-rated malleable iron construction\u003c\/li\u003e\n  \u003cli\u003eFIP x FIP thread pattern on both ends for standard NPT pipe connections\u003c\/li\u003e\n  \u003cli\u003eBlack finish suited for gas and air service applications\u003c\/li\u003e\n  \u003cli\u003eProduced to ASTM and applicable malleable iron fitting specifications\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 compatible with standard 3\/4 inch NPT threaded iron pipe systems rated for 150 lb malleable iron fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on service type. Shut off all gas or fluid supply and depressurize the line before disassembling or connecting any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly.
