Sized at 3\/8 inch by 1\/2 inch, it steps down pipe diameter inline without additional adapters. The black polypropylene construction resists corrosion and chemical exposure, making it well-suited for low-pressure fluid handling and plumbing distribution applications. It carries NSF 61 and NSF 372 certifications, confirming it meets standards for contact with potable water and low lead content. Plumbers and pipefitters typically install this fitting during rough-in or repair work on residential and light commercial water distribution systems.\u003c\/p\u003e\u003cp\u003eThis reducer nipple is used in residential and light commercial plumbing systems where a transition between 3\/8 inch and 1\/2 inch pipe is required. Common install scenarios include supply line connections, manifold drops, fixture supply branches, and irrigation sub-feeds. The MIPT x MIPT end configuration threads directly into female-threaded fittings or valves on both ends. Its lightweight polypropylene body keeps overall system weight low and eliminates galvanic corrosion concerns common with dissimilar metal connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch by 1\/2 inch reducer configuration for inline diameter transitions\u003c\/li\u003e\n\u003cli\u003eMIPT x MIPT end connections for direct threading into female-threaded ports\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction resists corrosion, scale, and common plumbing chemicals\u003c\/li\u003e\n\u003cli\u003eNSF 61 certified for potable water contact\u003c\/li\u003e\n\u003cli\u003eNSF 372 certified for low lead content compliance\u003c\/li\u003e\n\u003cli\u003eLightweight at under 0.02 pounds per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential and light commercial plumbing systems using standard MIPT-threaded pipe and fittings in 3\/8 inch and 1\/2 inch sizes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before threading any fitting. Apply thread sealant tape or paste to the male threads per IPC guidelines before making up connections. Do not over-torque polypropylene fittings, as the material is more susceptible to thread damage than metal alternatives.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer Nipple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/8 x 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: MIPT x MIPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.014 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF 61, NSF 372\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GREEN LEAF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RM 3812 P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GREEN LEAF","offers":[{"title":"Default Title","offer_id":51722209132850,"sku":"RM 3812 P","price":16.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/988a05c4495aa065a160172ec3ece9e3_75f394c0-fb8a-49dd-bd56-278778aaca6b.jpg?v=1788587433","url":"https:\/\/voomisupply.com\/products\/green-leaf-rm-3812-p-reducer-nipple-3-8-x-1-2-in-mipt","provider":"Voomi Supply","version":"1.0","type":"link"}
