Constructed from 304 stainless steel, this fitting provides corrosion resistance in both wet and dry service environments. The female NPT (FNPT) end threads onto standard NPT pipe or fittings, making it a straightforward mechanical connection. At a pressure rating of 150 psi and conforming to ISO standards, the K411H-04 is suited for low-to-medium pressure applications where a reliable, leak-resistant joint is required. Licensed plumbers and pipefitters are the primary installers of this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThe K411H-04 half coupling is used in residential and light commercial piping installations where a branch connection or pipe extension is needed on one end only. Its 25\/32 inch length makes it compact enough for tight installations. Common applications include water supply lines, compressed air distribution, and process piping where stainless steel is specified for corrosion resistance or sanitary requirements. The FNPT connection is compatible with standard NPT-threaded pipe and fittings across these system types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in wet and process environments\u003c\/li\u003e\n  \u003cli\u003eFNPT end connection threads directly onto standard NPT pipe or fittings\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for low-to-medium pressure service\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO standards for dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eCompact 25\/32 inch length fits restricted installation spaces\u003c\/li\u003e\n  \u003cli\u003eHalf coupling design for single-end threaded branch or extension connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded half coupling for use with 1\/4 inch NPT pipe and fittings in standard plumbing, HVAC, and industrial piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the IPC. Shut off and depressurize the system before making any threaded connections. Apply an approved thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-tighten threaded stainless steel fittings, as galling of the threads 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: 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: 304 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: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: K411H-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51716666655026,"sku":"K411H-04","price":31.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f2989fb893476aeb454f9979bf37e55.jpg?v=1788529964","url":"https:\/\/voomisupply.com\/products\/merit-brass-k411h-04-1-4-in-pipe-half-coupling-304-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
