Constructed from 304\/304L stainless steel, this fitting delivers strong corrosion resistance and structural integrity across a wide range of fluid handling applications. Rated to 3,000 psi, it is suited for demanding service conditions in industrial, commercial plumbing, and process piping installations. Both end connections are FNPT, allowing straightforward threaded assembly without welding or specialty tooling. Plumbers, pipefitters, and mechanical contractors typically specify this fitting for in-line diameter reductions in water, gas, and chemical service lines.\u003c\/p\u003e\n\u003cp\u003eThis reducer sees common use in residential and commercial mechanical rooms, industrial process piping, and utility systems where line size must be stepped down from 1-1\/4 inch to 3\/4 inch. The 304\/304L dual-grade material designation makes it appropriate for both standard and low-carbon stainless steel specifications, broadening its compatibility with existing piping systems and engineering requirements. The threaded FNPT x FNPT configuration suits retrofit and replacement work where welding is not practical or permitted.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304\/304L stainless steel construction provides corrosion resistance for water, gas, and chemical service\u003c\/li\u003e\n  \u003cli\u003e3,000 psi pressure rating handles high-pressure industrial and commercial piping applications\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT threaded ends allow tool-only installation with no welding required\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch to 3\/4 inch reduction covers one of the most common in-line diameter step-downs\u003c\/li\u003e\n  \u003cli\u003eDual-grade 304\/304L material meets both standard and low-carbon stainless specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded reducer fitting for use in standard NPT piping systems requiring a 1-1\/4 inch to 3\/4 inch female-to-female diameter reduction in stainless steel service.\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 mechanical and plumbing codes. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all NPT threads before assembly. Do not overtighten threaded connections, as stainless steel threads are susceptible to galling.\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: 1-1\/4 x 3\/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: 2.19 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-2012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51540421378354,"sku":"3412D-2012","price":131.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b20737a20f5927b271fa2667ce6ef47_7769c0be-3284-4bf9-8df6-edeeb06436ab.jpg?v=1785854685","url":"https:\/\/voomisupply.com\/products\/merit-brass-3412d-2012-pipe-reducer-1-1-4x3-4-fnpt-3000psi","provider":"Voomi Supply","version":"1.0","type":"link"}
