Machined from 316 stainless steel, it reduces from a 3\/8-inch to a 1\/8-inch FNPT connection and carries a pressure rating of 150 psi. At 1-7\/64 inches in length and weighing 0.11 pounds, this compact fitting is well-suited for tight plumbing or instrumentation assemblies. Plumbers, pipefitters, and mechanical contractors working with stainless steel pipe systems will find this fitting appropriate for both new construction and retrofit applications.\u003c\/p\u003e\n\u003cp\u003eThis reducer fitting is used in residential and commercial piping systems where a line-size reduction is required between two female-threaded ports. Typical applications include instrumentation tubing, chemical feed lines, compressed air systems, and process piping where corrosion resistance is a priority. The 316 stainless steel construction makes it a strong choice for environments exposed to moisture, mild chemicals, or marine-adjacent conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/8-inch FNPT to 1\/8-inch FNPT for in-line size transitions\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel construction offers superior corrosion resistance compared to 304 grade\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for low- to medium-pressure service\u003c\/li\u003e\n  \u003cli\u003eThreaded FNPT x FNPT end connections for straightforward installation with standard pipe wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ISO standards for dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eCompact at 1-7\/64 inches in length, fits confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded reducer for use in standard 3\/8-inch and 1\/8-inch female NPT piping systems where 316 stainless steel and 150 psi-rated fittings are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC guidelines. Depressurize and drain the system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to all male-threaded mating parts before assembly. Hand-tighten first, then wrench-tighten to a snug fit — do not overtighten stainless steel threads, as galling can occur.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/8 x 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K612-0602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51539038372146,"sku":"K612-0602","price":15.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1550302e5cbe9c4c99ad7338b4666221.jpg?v=1785833481","url":"https:\/\/voomisupply.com\/products\/merit-brass-k612-0602-pipe-reducer-3-8x1-8-316-ss-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
