Manufactured from 316 stainless steel, this fitting is built for corrosion resistance in demanding fluid and gas piping systems. It carries a 150 lb pressure class rating and uses a 1\/4-18 thread specification. The compact body measures 0.75 inches in length and 0.5 inches in height, making it suitable for tight-access installations. Licensed plumbers, pipefitters, and industrial maintenance professionals typically install this type of fitting in process piping, instrumentation lines, and mechanical systems.\u003c\/p\u003e\n\u003cp\u003eThis half coupling is designed for use in residential, commercial, and light industrial piping applications where a transition from threaded NPT pipe to a socket weld connection is required. The 316 stainless steel construction makes it well suited for environments with exposure to moisture, mild chemicals, or corrosive media. It falls within the SP-114 fittings product line, which covers 316 SS half couplings in a range of connection sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for corrosion resistance in wet and chemical environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch Female NPT on one end and 1\/4-inch Socket Weld on the other for mixed-connection transitions\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class rating for standard-duty piping service\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 thread specification for proper NPT engagement\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 0.75 inches in length and 0.5 inches in height for tight installations\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 piping systems requiring a 1\/4-inch Female NPT to 1\/4-inch Socket Weld transition in 150 lb service class applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC or ASME B31.3. Depressurize and isolate the piping system completely before removing or installing any fitting. The socket weld end requires proper fit-up and welding by a qualified welder; do not attempt to thread or mechanical-join the socket weld end. Apply thread sealant to the NPT end as appropriate for the service fluid.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Female NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Socket Weld\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 pounds\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63771MS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952074785074,"sku":"63771MS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f79c44e2606c631ffbef8499e7c66d4_2385dbc8-ea4d-4b76-a8fd-975ab805e26f.jpg?v=1791745875","url":"https:\/\/voomisupply.com\/products\/midland-industries-63771ms-half-coupling-1-4-in-npt-x-socket-weld-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
