It features a 1-inch nominal size with female national pipe taper (FNPT) threaded ends on both ports. This standard 90-degree elbow is used to change the direction of a threaded pipe run in low-pressure fluid, gas, or steam systems. The black finish indicates it is uncoated rather than galvanized, making it common in gas piping and fire sprinkler systems. Licensed plumbers, pipefitters, and gas fitters are the typical installers for this fitting class.\u003c\/p\u003e\u003cp\u003eThis elbow is suited for residential and light commercial piping applications where threaded malleable iron fittings are specified. Common uses include natural gas distribution lines, steam heating systems, compressed air systems, and water distribution piping that operates within the 150 lb pressure class. The 1-inch nominal size fits standard Schedule 40 threaded pipe of the same nominal diameter. Black malleable iron fittings of this type are widely specified on gas supply lines inside buildings where local codes permit threaded iron pipe.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFIG 3101 standard 90-degree elbow geometry for direction changes in threaded pipe runs\u003c\/li\u003e\n\u003cli\u003e1-inch nominal FNPT threaded ends for connection to standard tapered male pipe threads\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class rating suitable for steam, gas, air, and water service\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction provides strength and impact resistance over cast iron\u003c\/li\u003e\n\u003cli\u003eBlack finish for use in gas piping and non-corrosive dry applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1-inch nominal threaded malleable iron piping systems rated at 150 lb service class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or gas fitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the system completely before disassembling or threading any fitting. Apply an approved pipe thread sealant or PTFE tape rated for the service medium before making up the threaded joint. Do not over-tighten malleable iron fittings, as the material can crack under excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIGMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 810001206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525289771314,"sku":"BL90L1I-LF","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8789f9387be85e24ed0660f01a2eafcf_06a82ec0-261b-4ab9-b108-e255c0ceb14c.jpg?v=1785469688","url":"https:\/\/voomisupply.com\/products\/sigma-810001206-malleable-iron-black-pipe-elbow-1-in-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
