It measures 4 x 2 inches with a male NPT (MNPT) inlet and a female NPT (FNPT) outlet, allowing a 4-inch line to step down to a 2-inch connection. Overall length is 2-1\/8 inches. Molded from white PVC, this bushing is rated for Schedule 40 pressure service. Plumbers and pipefitters install this fitting in water distribution, irrigation, and industrial process lines where a threaded reduction is required. It is domestically manufactured.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for residential and commercial plumbing systems, irrigation mainlines, and light industrial process piping that operate under Schedule 40 pressure ratings. The MNPT x FNPT thread configuration allows it to be threaded directly into a female-threaded fitting or valve body while accepting a male-threaded pipe or fitting on the opposite end. It is a common solution when transitioning between pipe sizes within an all-threaded assembly without the need for additional couplings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSchedule 40 pressure rating for standard-service water and process piping\u003c\/li\u003e\n\u003cli\u003eMNPT x FNPT end configuration for direct threaded installation\u003c\/li\u003e\n\u003cli\u003e4 x 2 inch nominal size reduction in a compact 2-1\/8 inch length\u003c\/li\u003e\n\u003cli\u003eMolded PVC construction resists corrosion and chemical degradation in typical plumbing applications\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured to SCH 40\/STD dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard pressure fitting for Schedule 40 PVC threaded piping systems requiring a 4 x 2 inch threaded reduction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers following applicable IPC or local plumbing code requirements. Shut off and depressurize the system completely before removing any existing fittings. Apply thread sealant tape or compound to the male threads before assembly and tighten to hand-tight plus an additional one to two turns using strap wrenches — do not use pipe wrenches directly on PVC fittings as overtightening can crack the fitting. Avoid applying thread sealants that are incompatible with PVC.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: MNPT x FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule Rating\u003c\/strong\u003e: SCH 40\/STD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer Bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Type\u003c\/strong\u003e: Pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMethod of Manufacture\u003c\/strong\u003e: Molded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPEARS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 439-420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPEARS","offers":[{"title":"Default Title","offer_id":51233356742962,"sku":"439-420","price":68.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/Spears_439099_1N_c6f5bdc4-f57b-407b-83a6-29fb1b27fa52.jpg?v=1780098282","url":"https:\/\/voomisupply.com\/products\/spears-439-420-pvc-sch-40-reducer-bushing-4x2-in-mnpt-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
