Machined from 304 stainless steel, this fitting provides a corrosion-resistant connection point where a branch outlet or end connection is needed without a full coupling run. The socket weld design allows the pipe to be inserted into the fitting socket before welding, creating a strong, leak-resistant joint rated to 3,000 psi. It is installed by licensed pipefitters and plumbers working on process piping, steam lines, and industrial fluid systems where pressure integrity and material compatibility are critical requirements.\u003c\/p\u003e\u003cp\u003eThis half coupling is suited for commercial and industrial piping applications including process lines, steam distribution, hydraulic systems, and chemical transfer where 304 stainless steel is the specified material. The 3,000 psi pressure rating makes it appropriate for Class 3000 socket weld configurations per standard pipe fitting specifications. It serves as a branch connection or end fitting on 3\/4-inch nominal pipe runs in both above-ground and concealed installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction resists corrosion in wet, chemical, and steam environments\u003c\/li\u003e\n\u003cli\u003e3,000 psi pressure rating suitable for Class 3000 socket weld service\u003c\/li\u003e\n\u003cli\u003eSocket weld x socket weld end connection for full-penetration weld joints\u003c\/li\u003e\n\u003cli\u003e3\/4-inch fitting size for standard nominal pipe sizing\u003c\/li\u003e\n\u003cli\u003eCompact half coupling profile for branch outlet and terminal connection applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard component for Class 3000 socket weld piping systems using 3\/4-inch nominal pipe in stainless steel service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter or welder in accordance with applicable codes such as ASME B16.11 for socket weld fittings. Depressurize and drain the line completely before cutting into any existing piping. The pipe end must be cleaned and properly inserted to the required gap depth before tack welding and final weld passes. Post-weld inspection and pressure testing should follow the requirements of the governing piping code for the system service.\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: 3\/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\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: 0.62 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-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51699884818738,"sku":"SW3411HD-12","price":22.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0c93f531e1838c79b501b27171aff4c_ab4a0fd7-f2e9-4ec6-a0b7-af91d0beae0e.jpg?v=1788382567","url":"https:\/\/voomisupply.com\/products\/merit-brass-sw3411hd-12-half-coupling-3-4-in-304-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
