It features female NPT (FNPT) end connections on a 1-1\/2 inch nominal pipe size and is finished in black. Malleable iron construction provides the ductility needed to withstand mechanical stress and vibration in threaded pipe assemblies. This elbow is used to change flow direction in low-pressure piping systems and is a standard fitting for plumbing, gas distribution, and mechanical piping installations. Licensed plumbers and pipefitters are the primary installers of this fitting type.\u003c\/p\u003e\n\u003cp\u003eThis elbow is suited for residential and light commercial piping applications where a 90-degree directional change is required in a threaded iron pipe system. Typical uses include natural gas branch lines, steam and hot-water heating piping, compressed air distribution, and general industrial piping where a 150 lb malleable iron fitting meets system pressure requirements. The FNPT thread pattern conforms to standard NPT taper thread specifications for a reliable, leak-resistant mechanical joint when properly assembled with thread sealant or tape.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction for strength and resistance to vibration-induced cracking\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch nominal pipe size with FNPT end connections on both ports\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suitable for gas, steam, and compressed air service\u003c\/li\u003e\n  \u003cli\u003eBlack finish for standard non-galvanized piping systems\u003c\/li\u003e\n  \u003cli\u003eFIG 3101 designation for straightforward replacement and procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting for 1-1\/2 inch nominal threaded iron pipe systems rated at 150 lb service class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable local plumbing and mechanical codes. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant compound or PTFE tape to male threads before assembly. Do not over-tighten malleable iron fittings, as excessive torque can crack the casting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Pipe Size\u003c\/strong\u003e: 1-1\/2 inches\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 Rating\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 810001610\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524782227762,"sku":"BL90L112I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8789f9387be85e24ed0660f01a2eafcf_adaff46b-4d5f-4c62-9f76-5c24c3bdca2e.jpg?v=1785457338","url":"https:\/\/voomisupply.com\/products\/sigma-810001610-malleable-iron-elbow-1-1-2-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
