Machined from 316\/316L stainless steel, this fitting offers strong resistance to corrosion, including chloride-bearing environments, making it well suited for marine, chemical, and industrial process lines. The half coupling is rated to 3,000 psi, supporting demanding service conditions. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install this type of fitting where a branch connection or end connection is needed on a pipe without requiring a full coupling.\u003c\/p\u003e\n\u003cp\u003eThis half coupling is appropriate for residential and commercial plumbing, HVAC hydronic systems, compressed air lines, and light industrial process piping. The FNPT end accepts standard tapered male NPT pipe threads. The 316\/316L dual-certified material grade suits applications where weld-quality or low-carbon stainless is specified to reduce sensitization risk. Typical install scenarios include connecting a pipe run to a valve, gauge, or instrumented port where only one threaded engagement is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-certified 316\/316L stainless steel construction for corrosion resistance in aggressive environments\u003c\/li\u003e\n  \u003cli\u003e3,000 psi pressure rating for high-pressure fluid and gas service\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch FNPT connection accepts standard tapered male NPT threads\u003c\/li\u003e\n  \u003cli\u003eThreaded end connection for tool-only installation without welding\u003c\/li\u003e\n  \u003cli\u003eHalf coupling design provides a single-end threaded branch or termination point\u003c\/li\u003e\n  \u003cli\u003eCompact, low-profile fitting suited for tight installation spaces\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 1\/4 inch NPT threaded pipe systems requiring 316 or 316L stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC or ASME B31 piping codes. Depressurize and isolate the line completely before threading in or removing any fitting. Apply appropriate thread sealant or PTFE tape to male NPT threads before assembly. Do not over-torque the fitting, as stainless steel threads are susceptible to galling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Half Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/4 inch\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\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: 0.0772 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: 3611HD-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51692660752690,"sku":"3611HD-04","price":81.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a972cecbecf550fb0343c54cd7490c8b.jpg?v=1788300762","url":"https:\/\/voomisupply.com\/products\/merit-brass-3611hd-04-half-coupling-1-4-in-316-ss-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
