Machined from 304 stainless steel, it provides solid corrosion resistance in both wet and dry service environments. The female NPT (FNPT) end accepts standard tapered pipe threads for a secure, leak-resistant joint. At 5\/8 inch in length and rated to 150 psi, this fitting suits low-to-medium pressure applications where stainless construction is required. Licensed plumbers and pipefitters install this type of coupling to extend a pipe run, connect to a valve or equipment port, or cap off a branch connection at a threaded inlet.\u003c\/p\u003e\n\u003cp\u003eThe K411H-02 is suited for residential and light commercial plumbing, HVAC hydronic piping, compressed air lines, and general industrial fluid systems where 304 stainless steel is specified for corrosion resistance or cleanliness requirements. The 1\/8 inch fitting size is commonly found on instrument taps, gauge ports, and small-diameter branch connections. This fitting meets ISO standards and is appropriate wherever a threaded half coupling is required at this size and pressure class.\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 industrial environments\u003c\/li\u003e\n  \u003cli\u003eFNPT (female NPT) threaded connection for compatibility with standard tapered pipe threads\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for low-to-medium pressure service\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch length in a compact 1\/8 inch fitting size\u003c\/li\u003e\n  \u003cli\u003eMeets ISO standards for dimensional and performance consistency\u003c\/li\u003e\n  \u003cli\u003eHalf coupling design for single-end pipe joining or equipment port connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded half coupling for 1\/8 inch NPT pipe systems requiring 304 stainless steel fittings at 150 psi service conditions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter. Shut off and depressurize the pipe system before removing or installing any threaded fittings. Apply a suitable thread sealant or PTFE tape to the male threads before makeup to ensure a leak-free joint. Follow applicable IPC or IFGC guidelines and local code requirements for pipe joining and pressure testing after installation.\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\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT (Female NPT Threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 Stainless Steel\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: 5\/8 inch\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: 0.02 pounds\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: K411H-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51543497507122,"sku":"K411H-02","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f0952d71015e395782bf3649a8c79eb.jpg?v=1785919542","url":"https:\/\/voomisupply.com\/products\/merit-brass-k411h-02-half-coupling-1-8-in-fnpt-304-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
