Reducer couplings allow technicians to transition between pipe sizes without adding extra fittings or offsets, keeping runs compact and leak-prone joint count low. Stainless steel construction resists corrosion in wet, chemical-exposure, and outdoor environments. This fitting is sized for common small-bore piping work and is sold individually, making it straightforward to order the exact quantity needed for a job. Plumbers, pipefitters, and HVAC installers working with threaded pipe systems will find this coupling a direct, reliable component for pipe-size transition tasks.\u003c\/p\u003e\n\u003cp\u003eThis reducer coupling suits residential and light commercial plumbing, HVAC condensate and refrigerant piping, compressed air lines, and general fluid-handling systems where NPT-threaded stainless steel fittings are specified. It is appropriate for applications requiring corrosion resistance beyond what standard carbon steel or brass fittings provide, such as coastal installations, chemical-adjacent environments, or potable water systems where stainless is preferred. The NPT end connection is the standard tapered thread used throughout North American plumbing and mechanical systems, ensuring broad fitment across common pipe assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction provides corrosion resistance in wet and chemically aggressive environments\u003c\/li\u003e\n  \u003cli\u003eNPT threaded ends conform to standard North American tapered pipe thread specifications\u003c\/li\u003e\n  \u003cli\u003eReducer coupling design transitions between two different pipe diameters in a single fitting\u003c\/li\u003e\n  \u003cli\u003eCompact profile helps minimize space requirements in tight pipe runs\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for precise quantity ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for NPT-threaded stainless steel pipe systems requiring an inline reducer coupling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the specific system type. Apply an appropriate thread sealant or PTFE tape to the NPT threads before assembly and tighten to hand-tight plus wrench turns as appropriate for the pipe material — do not overtighten stainless threads, as galling can occur. Depressurize and drain the affected line fully before removing any existing fitting or installing this coupling. Verify the system pressure and fluid compatibility fall within the fitting material ratings before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1.46 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4RSB3\/4X1\/8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695568552242,"sku":"4RSB3\/4X1\/8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da2c93c6c239ce7bb1c12a6cd4d6d296.jpg?v=1788336552","url":"https:\/\/voomisupply.com\/products\/value-collection-4rsb3-4x1-8-ss-reducer-coupling-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
