Manufactured from 304 stainless steel, this fitting provides a rated working pressure of 3,000 psi, making it suitable for demanding industrial and mechanical piping applications. A half coupling connects a branch line to a run of pipe using a single socket weld end, allowing a pipe to be welded directly into the fitting. Licensed pipefitters and mechanical contractors typically install this type of fitting in process, utility, and instrumentation piping systems where corrosion resistance and pressure integrity are required.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and commercial mechanical systems as well as light industrial process piping where 304 stainless steel is specified for its corrosion resistance. The socket weld by socket weld end connection configuration requires field welding by a qualified welder. Common applications include steam lines, hydraulic systems, chemical distribution headers, and compressed gas distribution where a Class 3000 forged fitting is called out by the piping specification or engineer of record.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction resists corrosion in wet and chemically active environments\u003c\/li\u003e\n\u003cli\u003e3,000 psi pressure rating suits Class 3000 piping system specifications\u003c\/li\u003e\n\u003cli\u003eSocket weld by socket weld end connections for full-penetration field welds\u003c\/li\u003e\n\u003cli\u003eHalf coupling design simplifies branch connections to pipe runs\u003c\/li\u003e\n\u003cli\u003eCompact 1\/8 inch fitting size for small-bore instrumentation and utility lines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for Class 3000 socket weld piping systems specified with 304 stainless steel half couplings in 1\/8 inch pipe size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a qualified welder following applicable welding procedures and codes such as ASME B31.1 or B31.3 depending on the service. Depressurize and isolate the piping system fully before any welding or modification work begins. Verify the base pipe material is compatible with 304 stainless steel filler materials to avoid dissimilar-metal weld issues. Post-weld inspection requirements should follow the project piping specification or authority having jurisdiction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaterial Grade\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Socket Weld x Socket Weld\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: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SW3411HD-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51538918211890,"sku":"SW3411HD-02","price":23.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0c93f531e1838c79b501b27171aff4c.jpg?v=1785829599","url":"https:\/\/voomisupply.com\/products\/merit-brass-sw3411hd-02-pipe-half-coupling-1-8-in-304-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
