It uses National Pipe Taper (NPT) end connections on both ends, creating a pressure-tight mechanical joint when properly assembled. The stainless steel construction resists corrosion in wet, chemical, and moderate-temperature environments. At 0.06 pounds, this is a compact, lightweight fitting suited for plumbing, HVAC piping, and industrial fluid-handling systems where a threaded size reduction is required without additional fittings or adapters.\u003c\/p\u003e\u003cp\u003eThis reducer coupling is used in residential and light commercial piping systems where a transition between two NPT-threaded pipe sizes is needed inline. Common applications include water supply lines, compressed air systems, hydraulic lines, and process piping where system pressure ratings and corrosion resistance are a priority. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers of this type of fitting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction for corrosion resistance in wet and chemical-exposure environments\u003c\/li\u003e\n\u003cli\u003eNPT threaded end connections on both ends for standard pipe thread engagement\u003c\/li\u003e\n\u003cli\u003eReducer coupling configuration allows inline transition between two pipe sizes\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.06 pounds\u003c\/li\u003e\n\u003cli\u003eSingle-piece fitting eliminates the need for additional adapters at a size transition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install reducer coupling for systems using standard NPT-threaded stainless steel pipe fittings.\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 local plumbing code requirements. Shut off and depressurize the supply line completely before removing or installing any threaded fitting. Apply thread sealant tape or pipe compound rated for the fluid type and pressure of the system to the male NPT threads before assembly. Do not over-torque stainless steel fittings, as galling of the threads can occur.\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\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4RSB3\/8X1\/8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689763438898,"sku":"4RSB3\/8X1\/8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a8baec81c3ff550678264f9bce8e58b.jpg?v=1788264051","url":"https:\/\/voomisupply.com\/products\/value-collection-4rsb3-8x1-8-ss-reducer-coupling-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
