Rated at 3,000 psi, this fitting provides a strong, full-penetration weld connection on one end, making it well suited for terminating pipe runs or connecting pipe to equipment flanges and valve bodies. The 304 stainless steel construction offers solid corrosion resistance in a wide range of fluid service applications. Licensed pipefitters and plumbers install this coupling in industrial, commercial, and process piping where code-compliant, permanent connections are required.\u003c\/p\u003e\n\u003cp\u003eThis half coupling is sized for 1-1\/4 inch pipe and uses a socket weld end connection on both engaging faces. It is commonly found in process piping, steam service, hydraulic lines, and general industrial fluid systems where high working pressures and corrosion resistance are priorities. The 3,000 psi pressure rating makes it appropriate for Class 3000 socket weld fitting applications per ASME B16.11 standards, typical in refineries, plants, and commercial mechanical rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction for broad corrosion resistance in fluid and steam service\u003c\/li\u003e\n  \u003cli\u003e3,000 psi pressure rating suitable for Class 3000 high-pressure piping systems\u003c\/li\u003e\n  \u003cli\u003eSocket weld end connection provides a permanent, full-penetration weld joint\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch fitting size for standard pipe terminations and branch connections\u003c\/li\u003e\n  \u003cli\u003eHalf coupling design allows pipe-to-equipment or pipe-end termination without a full coupling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Class 3000 socket weld half coupling for use with 1-1\/4 inch pipe in industrial and commercial stainless steel piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter or plumber in accordance with ASME B31.1, B31.3, or applicable local piping codes. The pipe end must be cut square, deburred, and inserted fully into the socket before welding. De-energize and depressurize the system completely before any cutting, fitting, or welding work begins. Verify filler metal compatibility with 304 stainless steel base material prior to welding.\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: 1-1\/4 inches\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: 1.31 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: SW3411HD-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51694155956530,"sku":"SW3411HD-20","price":42.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0c93f531e1838c79b501b27171aff4c_0908743d-2383-41db-afe1-5b2ec782fad0.jpg?v=1788320999","url":"https:\/\/voomisupply.com\/products\/merit-brass-sw3411hd-20-pipe-half-coupling-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
