It features female National Pipe Taper (FNPT) threads on both ends and is rated for service up to 3,000 psi, making it suitable for demanding pressure applications. Constructed from 304\/304L stainless steel, this fitting offers strong resistance to corrosion in a wide range of media. Licensed plumbers and pipefitters install this type of reducer when transitioning from a 1-1\/2-inch line down to a 3\/8-inch branch or connection point.\u003c\/p\u003e\u003cp\u003eThis reducer is appropriate for residential and commercial piping applications where a threaded, stainless steel fitting is required. Typical uses include water supply systems, compressed air lines, and light industrial fluid handling where corrosion resistance and pressure integrity are priorities. The FNPT x FNPT configuration allows direct makeup with standard NPT-threaded pipe and fittings on both the larger and smaller port sides.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual FNPT end connections accept standard NPT-threaded pipe on both sides\u003c\/li\u003e\n\u003cli\u003e3,000 psi pressure rating suited for high-pressure fluid and gas service\u003c\/li\u003e\n\u003cli\u003e304\/304L stainless steel construction provides corrosion resistance in wet and chemical environments\u003c\/li\u003e\n\u003cli\u003eCompact reducer profile for inline diameter transitions without additional fittings\u003c\/li\u003e\n\u003cli\u003eWeighs 3.31 pounds — substantial forged construction for dependable thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style threaded reducer for standard NPT piping systems requiring a 1-1\/2-inch to 3\/8-inch diameter transition in stainless steel service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the service application. Shut off system pressure and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads being engaged, and tighten to full thread engagement using a pipe wrench — avoid over-torquing, which can crack fittings or distort threads. Verify pressure integrity with a system pressure test before returning to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-1\/2 x 3\/8 inches\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\u003eMaterial Grade\u003c\/strong\u003e: 304 \/ 304L Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.31 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: 3412D-2406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541484699954,"sku":"3412D-2406","price":66.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b20737a20f5927b271fa2667ce6ef47_1b66ee34-8e98-4d4c-b9f2-ed15c7327993.jpg?v=1785877491","url":"https:\/\/voomisupply.com\/products\/merit-brass-3412d-2406-pipe-reducer-1-1-2-x-3-8-in-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
