It provides a full-port, inline connection between two female NPT-threaded pipe ends and is rated to 3,000 psi working pressure. The dual-grade 316\/316L material delivers corrosion resistance suited to demanding fluid handling, chemical, and process piping applications. Licensed plumbers, pipefitters, and mechanical contractors typically install this fitting in systems where standard carbon steel or brass would face corrosion from aggressive media, salt environments, or high-purity fluid requirements.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in residential and commercial plumbing, HVAC hydronic systems, industrial process lines, and marine or coastal installations where stainless steel fittings are specified. Its small 1\/8 inch size makes it common in instrument tubing runs, pilot lines, and low-flow control circuits. The threaded FNPT x FNPT end connections allow installation without welding, making it accessible for field service and retrofit work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316\/316L dual-grade stainless steel construction for superior corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3,000 psi pressure rating suitable for high-pressure process and plumbing applications\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT threaded end connections for tool-only, no-weld installation\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch fitting size fits standard NPT pipe and fittings of the same size\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at approximately 0.13 pounds\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 compatible with standard 1\/8 inch NPT threaded pipe systems requiring stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements for threaded stainless steel fittings. Shut off and depressurize the system completely before removing or installing any threaded coupling. Apply an appropriate thread sealant or PTFE tape rated for the service fluid and pressure before making up the connection. Do not over-torque stainless steel threads, as galling can permanently damage the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\/316L Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\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: 3611D-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542789390642,"sku":"3611D-02","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dfd8dcfebdfd089a100736c879c3f47.jpg?v=1785907515","url":"https:\/\/voomisupply.com\/products\/merit-brass-3611d-02-pipe-coupling-1-8-in-ss-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
