It features a 1\/4-inch female NPT inlet and a male NPT outlet, making it a standard union-style adapter used to extend or transition threaded pipe runs. Rated at Class 125, it is suited for general-purpose plumbing, HVAC hydronic lines, compressed air, and light industrial piping. Licensed plumbers and pipefitters install this fitting as part of threaded pipe assemblies where a female-to-male NPT connection is required. The brass construction provides solid corrosion resistance across a range of service fluids.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and light commercial applications where 1\/4-inch NPT threaded connections are standard. Typical install scenarios include branch connections on water supply lines, instrument takeoffs, and HVAC control line piping. The FNPT x MNPT configuration allows it to serve as a close nipple adapter or a thread-direction transition point within an existing threaded assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-inch fitting size with FNPT x MNPT end connections for direct threaded pipe assembly\u003c\/li\u003e\n\u003cli\u003eClass 125 pressure rating suitable for general-purpose plumbing and HVAC piping\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance in water, air, and compatible fluid service\u003c\/li\u003e\n\u003cli\u003eCompact, lightweight design at 0.15 pounds for easy handling in tight spaces\u003c\/li\u003e\n\u003cli\u003eStandard NPT threading for compatibility with common threaded pipe and fittings stock\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\/4-inch NPT threaded pipe systems in residential and light commercial plumbing and HVAC applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the water or fluid supply before working on any threaded connection. Apply a compatible thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free joint. Do not overtighten threaded brass fittings, as this can crack the fitting body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: FNPT x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C103A-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542764192050,"sku":"C103A-04","price":63.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/485877b6107285cda31fc9940bc43bec.jpg?v=1785906697","url":"https:\/\/voomisupply.com\/products\/merit-brass-c103a-04-brass-pipe-fitting-1-4-in-fnpt-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
