Rated to 2,800 psi, this adapter handles demanding instrumentation and process piping applications where a reliable threaded reduction is required. The all-brass construction resists corrosion and provides the dimensional stability needed in both gas and liquid service lines. Plumbers, pipefitters, and instrumentation technicians routinely specify this type of adapter when transitioning between pipe sizes without adding unnecessary fittings to the assembly.\u003c\/p\u003e\u003cp\u003eThis reducing adapter is suited for use in instrumentation systems, compressed air lines, hydraulic circuits, and general industrial plumbing where a 1\/4-inch to 1\/8-inch NPT thread reduction is needed. Its straight fitting shape makes it appropriate for tight spaces and inline routing. The FNPT x MNPT end configuration allows it to thread directly into a female-ported valve, manifold, or instrument body while accepting a male-threaded pipe or hose assembly on the outlet side.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2,800 psi pressure rating suitable for instrumentation and process piping service\u003c\/li\u003e\n\u003cli\u003eFNPT x MNPT threaded ends for direct inline pipe size reduction\u003c\/li\u003e\n\u003cli\u003eStraight fitting shape for compact, inline installations\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance in air, water, and compatible fluid service\u003c\/li\u003e\n\u003cli\u003eMeets ANSI\/ASME B1.20.1, ANSI\/ASME B31.1, and ANSI\/ASME B31.3 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ANSI\/ASME B1.20.1-compliant NPT threaded reducing adapter for use in instrumentation-class piping systems requiring a 1\/4-inch FNPT to 1\/8-inch MNPT connection.\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 piping codes including ANSI\/ASME B31.1 and B31.3. Depressurize and isolate the line completely before removing or installing any threaded fitting. Apply thread sealant or PTFE tape to the male threads per the system fluid compatibility requirements. Do not overtighten brass fittings, as this can crack the fitting body or damage mating threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducing Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/4 x 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: FNPT x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 2,800 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\/Finish\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\/ASME B1.20.1, ANSI\/ASME B31.1, ANSI\/ASME B31.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: USA INDUSTRIALS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZUSA-PF-4990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"USA INDUSTRIALS","offers":[{"title":"Default Title","offer_id":51995098317106,"sku":"ZUSA-PF-4990","price":47.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d231e5bb79d80b9502429053287d9918_ff381a9b-4a49-4870-8d58-c31081d13911.jpg?v=1789992456","url":"https:\/\/voomisupply.com\/products\/usa-industrials-zusa-pf-4990-brass-reducing-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
