It uses National Pipe Taper (NPT) end connections on both ends, providing a secure, leak-resistant seal when properly installed. Constructed from stainless steel, this fitting offers corrosion resistance suitable for demanding fluid and gas service applications. Plumbers, pipefitters, and mechanical contractors install this type of fitting during new construction and retrofit work where pipe diameter transitions are required in pressurized systems.\u003c\/p\u003e\u003cp\u003eThis reducer coupling is suited for use in residential, commercial, and light industrial piping systems where NPT threaded connections are standard. It is commonly installed in water supply lines, compressed air systems, and process piping wherever a reduction in pipe size is needed inline. The stainless steel construction makes it appropriate for applications involving moisture, mild chemicals, or environments that would corrode carbon steel fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReducer coupling design transitions between two different pipe diameters in a single fitting\u003c\/li\u003e\n\u003cli\u003eNPT threaded end connections on both ends for standard threaded pipe assembly\u003c\/li\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance in wet and chemical-exposure environments\u003c\/li\u003e\n\u003cli\u003eCompact form factor suitable for installations with limited clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard installation fitting for NPT threaded piping systems requiring an inline diameter reduction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Depressurize and drain the system completely before removing any existing fittings or installing this coupling. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly to ensure a leak-free joint. Do not over-tighten threaded connections, as this can crack fittings or damage threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer Coupling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.79 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: Value Collection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4RSB4X2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698604310834,"sku":"4RSB4X2","price":115.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c62eba8a0e3decbed8c2783740b1c9f5.jpg?v=1788365344","url":"https:\/\/voomisupply.com\/products\/value-collection-4rsb4x2-ss-reducer-coupling-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
