It features a male NPT inlet on one end and a female NPT outlet on the other, allowing a direction change without the need for an additional nipple. The black oxide finish provides baseline corrosion resistance for dry or low-moisture environments. At 3\/4 inch nominal size, this fitting is a standard choice for gas distribution, compressed air, and general-purpose piping systems in both residential and light commercial applications. Licensed plumbers and pipefitters install this fitting where a compact 90-degree turn is required in threaded iron pipe runs.\u003c\/p\u003e\n\u003cp\u003eThis street elbow is suited for 3\/4 inch threaded iron pipe systems in residential and commercial mechanical rooms, gas supply lines, steam and hot-water heating systems, and industrial process piping. The MNPT x FNPT configuration allows the fitting to thread directly into a pipe or tee without an intermediate nipple, saving space in tight installations. It is appropriate for low-pressure gas, steam, water, and air service within the 150 lb pressure class rating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFIG 3104 street elbow geometry for compact 90-degree direction changes in threaded iron piping\u003c\/li\u003e\n  \u003cli\u003eMNPT x FNPT end style eliminates the need for an additional close nipple\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class rating suitable for gas, steam, water, and compressed air service\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides strength and impact resistance in mechanical piping applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for standard corrosion protection in typical indoor or sheltered installations\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch nominal size matches common residential and light commercial pipe sizes\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 for 3\/4 inch nominal threaded malleable iron pipe systems rated to the 150 lb pressure class.\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 codes such as the IPC or IFGC. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus the appropriate number of turns for the pipe size — do not overtighten malleable iron fittings as they can crack. Verify system pressure and leak-test all joints after returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3104\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: MNPT x FNPT\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 Oxide\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: 810027409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51524357390642,"sku":"BL45STL34I-LF","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2bd20d2bc24370f6cb2d6e9ea6d90e9.jpg?v=1785446865","url":"https:\/\/voomisupply.com\/products\/sigma-810027409-street-elbow-3-4-in-mnpt-x-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
