Both ends feature MIPT (Male Iron Pipe Thread) connections, allowing direct threaded engagement with female-threaded fittings or ports. Constructed from black polypropylene, this fitting offers corrosion resistance and chemical compatibility suited to potable water and light-duty plumbing applications. It is NSF 61 and NSF 372 certified, confirming compliance with drinking water system standards and low-lead requirements. Plumbers and pipefitters install this fitting where a threaded size reduction is needed without an additional coupling or bushing.\u003c\/p\u003e\n\u003cp\u003eThis reducer nipple is used in residential and light commercial plumbing systems wherever a 1\/4-inch to 3\/8-inch MIPT-to-MIPT thread reduction is required. Typical applications include water filtration systems, RO (reverse osmosis) installations, ice maker supply lines, and similar low-pressure potable water circuits. Its compact form factor allows installation in tight spaces where metal fittings may be prone to corrosion or where plastic-to-plastic compatibility is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/8-inch to 1\/4-inch male pipe thread in a single fitting\u003c\/li\u003e\n  \u003cli\u003eMIPT x MIPT end connections for direct threaded installation\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction resists corrosion and common household chemicals\u003c\/li\u003e\n  \u003cli\u003eNSF 61 certified for potable water contact\u003c\/li\u003e\n  \u003cli\u003eNSF 372 certified for low-lead compliance\u003c\/li\u003e\n  \u003cli\u003eBlack color finish standard\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 residential and light commercial plumbing systems requiring a 1\/4-inch x 3\/8-inch MIPT x MIPT polypropylene reducer nipple.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed plumbers or qualified pipefitters working on potable water or fluid distribution systems. Shut off the water supply and relieve system pressure completely before removing or installing threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before engagement; do not overtighten polypropylene fittings, as the material is subject to cracking under excessive torque. Verify local plumbing code compliance, including IPC requirements, before installation in potable water systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1\/4 x 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: MIPT x MIPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: NSF 61, NSF 372\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: GREEN LEAF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RM 1438 P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GREEN LEAF","offers":[{"title":"Default Title","offer_id":51696439886130,"sku":"RM 1438 P","price":16.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/988a05c4495aa065a160172ec3ece9e3_26cf103a-2fa1-4905-8a24-69d847eb8792.jpg?v=1788342710","url":"https:\/\/voomisupply.com\/products\/green-leaf-rm-1438-p-reducer-nipple-1-4-x-3-8-in-mipt","provider":"Voomi Supply","version":"1.0","type":"link"}
