It transitions from a 1\/2-inch female thread on one end to a 1\/4-inch female thread on the other, making it a standard solution for reducing line diameter in plumbing and fluid system assemblies. This type of fitting is typically installed by licensed plumbers or pipefitters working on compressed air, water, gas, or hydraulic systems where NPT threaded connections are specified. The black finish indicates a non-galvanized carbon steel or black malleable iron construction suited for gas and air service lines.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is commonly used in residential and light commercial installations where a pipe run transitions from a 1\/2-inch main to a 1\/4-inch branch or instrument tap. Typical applications include compressed air distribution, natural gas branch lines, fuel oil systems, and general-purpose threaded pipe assemblies. It fits wherever a standard NPT reducing coupling of this size is specified, and is suitable for both new construction and maintenance and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1\/2-inch NPT to 1\/4-inch NPT in a single fitting\u003c\/li\u003e\n  \u003cli\u003eNPT end connections for standard tapered thread engagement and pressure-tight seal\u003c\/li\u003e\n  \u003cli\u003eBlack finish construction suited for gas, air, and general fluid service\u003c\/li\u003e\n  \u003cli\u003eCompact coupling form factor with no center hex extension, suitable for tight spaces\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 40175303 for procurement classification compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation reducing coupling for standard 1\/2-inch by 1\/4-inch NPT threaded pipe systems.\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 and national codes, including the International Plumbing Code or International Fuel Gas Code as appropriate. Shut off system pressure and depressurize the line before removing or installing any threaded fitting. Apply thread sealant or PTFE tape to the male threads before assembly; do not apply sealant to the first one or two threads. Use appropriately sized pipe wrenches to avoid over-torquing and cracking the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/2 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175303\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: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FF4186-0804-2S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51540250493234,"sku":"FF4186-0804-2S","price":468.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7659c93f1eb81f6b44777e289653bc9a.jpg?v=1785850251","url":"https:\/\/voomisupply.com\/products\/eaton-ff4186-0804-2s-black-reducing-coupling-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
