A half coupling provides a branch or end connection on a pipe run where only one female end is needed. This fitting uses a socket weld end connection and is also threaded, giving installers flexibility in how it is incorporated into a high-pressure piping assembly. The 316 stainless steel construction provides strong resistance to corrosion and chloride environments, making it well suited for process, chemical, and marine-adjacent piping systems. Licensed plumbers, pipefitters, and industrial mechanical contractors are the primary installers of this fitting type.\u003c\/p\u003e\u003cp\u003eThis half coupling is intended for use in high-pressure pipe systems where a 1\/4-inch branch or terminal connection is required. The socket weld configuration is common in commercial and industrial settings where leak-tight, permanent joints are needed under elevated pressure or temperature conditions. Applications include instrumentation lines, chemical process piping, steam service, and hydraulic systems where 316 stainless steel is specified for its corrosion resistance. The 3,000 psi pressure rating places this fitting in the Class 3000 forged fitting category, appropriate for small-bore high-pressure runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e316 stainless steel construction resists corrosion and chloride attack\u003c\/li\u003e\n\u003cli\u003e3,000 psi pressure rating suits high-pressure industrial and process applications\u003c\/li\u003e\n\u003cli\u003eSocket weld end connection provides a permanent, leak-resistant joint\u003c\/li\u003e\n\u003cli\u003eThreaded configuration allows versatile integration into the piping assembly\u003c\/li\u003e\n\u003cli\u003eHalf coupling design for branch or end connections on 1\/4-inch pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style Class 3000 half coupling for 1\/4-inch socket weld pipe systems where 316 stainless steel material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of socket weld fittings should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and piping codes. Depressurize and isolate the line completely before cutting in or modifying any fitting. Socket weld joints require proper fit-up, gap spacing, and fillet weld per applicable welding procedures before returning the system to service. Do not exceed the rated working pressure of 3,000 psi for this fitting size and material grade.\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\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 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: 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: 0.06 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: SW3611HD-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541678293298,"sku":"SW3611HD-04","price":19.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0c93f531e1838c79b501b27171aff4c_0bcdc086-4045-4730-8186-6c80b76bd24f.jpg?v=1785882007","url":"https:\/\/voomisupply.com\/products\/merit-brass-sw3611hd-04-half-coupling-1-4-in-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
