It reduces a 3\/4 inch female NPT (FNPT) inlet down to a 3\/8 inch FNPT outlet and carries a 3,000 psi pressure rating. The dual-grade 316\/316L designation means it meets both standard and low-carbon corrosion resistance requirements, making it suitable for chemical process, marine, food service, and instrumentation applications. Licensed plumbers, pipefitters, and industrial maintenance technicians install this fitting in threaded piping assemblies where a secure, leak-resistant diameter transition is required.\u003c\/p\u003e\n\u003cp\u003eThis reducer is suited for residential and commercial piping systems that require a step-down transition between 3\/4 inch and 3\/8 inch threaded lines. Typical applications include process piping, hydraulic lines, instrumentation tubing, and fluid handling systems where stainless steel is specified for corrosion resistance or sanitary compliance. The FNPT x FNPT configuration accepts standard NPT male threaded pipe on both ends, fitting into any compliant threaded assembly without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316\/316L stainless steel construction for superior corrosion resistance in wet, chemical, and marine environments\u003c\/li\u003e\n  \u003cli\u003e3,000 psi pressure rating supports high-pressure piping and instrumentation service\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch x 3\/8 inch reduction in a single fitting eliminates the need for multiple adapters\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard NPT threaded pipe compatibility\u003c\/li\u003e\n  \u003cli\u003eLow-carbon 316L grade reduces risk of intergranular corrosion after welding or high-heat exposure\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 any 3\/4 inch to 3\/8 inch NPT threaded piping system requiring 316 or 316L stainless steel fittings rated to 3,000 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters following applicable IPC and ASME B1.20.1 thread standards. Shut down system pressure and depressurize the line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly to ensure a leak-free joint. Do not over-torque stainless steel fittings, as galling of the threads can occur.\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\/4 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: 316\/316L Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 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: 3612D-1206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51539377193266,"sku":"3612D-1206","price":67.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b20737a20f5927b271fa2667ce6ef47_ce2c5c49-5ed9-4ebd-87eb-1b5d59ac5048.jpg?v=1785838919","url":"https:\/\/voomisupply.com\/products\/merit-brass-3612d-1206-pipe-reducer-3-4x3-8-fnpt-3000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
