It features a socket weld by socket weld end connection with threaded engagement, making it a Class 150 fitting suitable for joining same-size pipe runs in demanding piping systems. The 316 stainless steel construction provides strong resistance to corrosion and chloride environments, which is critical in process, marine, and chemical piping applications. At 0.66 pounds, this is a compact, single-piece fitting sized for standard 1-1\/4 inch pipe. Licensed plumbers and pipefitters are the primary installers on commercial and industrial jobs.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in commercial and industrial piping systems where corrosion resistance and pressure integrity are required. Typical applications include process piping, food service lines, marine plumbing, and chemical handling systems where 316 stainless steel is specified over 304 for its improved chloride resistance. The socket weld configuration suits permanent, high-integrity pipe joints in environments where threaded-only connections are not preferred. It is sold individually and is appropriate for both new construction and retrofit piping work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for superior corrosion and chloride resistance\u003c\/li\u003e\n  \u003cli\u003eSocket weld by socket weld end connection for strong, permanent pipe joints\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating suitable for Class 150 piping systems\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch fitting size for standard pipe runs\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type for secure engagement\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with no minimum order requirement beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install fitting for 1-1\/4 inch schedule pipe systems requiring Class 150 socket weld couplings in 316 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of socket weld fittings should be performed by a licensed plumber or qualified pipefitter in accordance with applicable codes, including ASME B31.3 for process piping or local plumbing codes as required. Before beginning work, isolate and de-pressurize the pipe section and verify the line is free of fluid. Socket weld joints require proper fit-up and welding by a certified welder — do not use this fitting with adhesive or press-fit methods not rated for this connection type. Inspect the socket interior and pipe end for burrs or debris before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 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: 316 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\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.66 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: SWM611-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542921642290,"sku":"SWM611-20","price":34.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04c1b4b5ff06c61810ec70aad2c65406_cf0c3a07-f0ce-473b-a03b-ed0c8e56309e.jpg?v=1785911060","url":"https:\/\/voomisupply.com\/products\/merit-brass-swm611-20-pipe-coupling-1-1-4-in-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
