Constructed from 304\/304L stainless steel, this reducer delivers corrosion resistance suited for demanding fluid-handling and gas-distribution systems. It carries a 3,000 psi pressure rating, making it appropriate for medium- to high-pressure service lines. Both end connections are FNPT, requiring male-threaded mating fittings on each side. Plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this fitting in commercial and light industrial piping assemblies.\u003c\/p\u003e\n\u003cp\u003eThis reducer is used wherever a piping run must step down from a 3\/8-inch line to a 1\/4-inch line while maintaining a fully threaded, leak-resistant joint. Typical applications include compressed air distribution, hydraulic supply lines, instrumentation tubing, chemical process piping, and general industrial fluid systems where 304 or 304L stainless steel is specified for corrosion resistance. Its compact body suits tight-clearance panel assemblies and equipment manifolds equally well.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304\/304L stainless steel construction provides corrosion resistance in wet, chemical, and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e3,000 psi pressure rating supports medium- to high-pressure service applications\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections on both sides accept standard male-threaded pipe fittings\u003c\/li\u003e\n  \u003cli\u003eThreaded configuration allows tool-only installation without welding or special tooling\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch to 1\/4-inch reduction covers one of the most common pipe-size step-down transitions in commercial and industrial systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded pipe reducer for use in 3\/8-inch to 1\/4-inch FNPT piping systems where 304 or 304L stainless steel construction is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping codes. Shut off and depressurize the supply line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads of the mating fittings before engagement. Do not over-torque; use a pipe wrench on the fitting flats only and avoid contact with any adjacent components that could transmit excess stress into the fitting body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/8 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 \/ 304L Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3412D-0604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542424846642,"sku":"3412D-0604","price":34.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0a07cd76e84b0755c8bba626b1f14f6.jpg?v=1785900190","url":"https:\/\/voomisupply.com\/products\/merit-brass-3412d-0604-pipe-reducer-3-8-x-1-4-inch-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
